I have tried it both ways and the supplied soft large bore fuel line did work, however the small hard line as described by John did work MUCH better! It's little nuggets of knowledge like this that should make John's entire series on these heaters mandatory for anyone purchasing one of these heaters. You owe it to yourself to watch this incredibly well researched series. Tons of knowledge in each episode. Thank you John for all of the hard work that these videos must have entailed!
Hi 74 Willy, First thanks for your kind comments. Yes, the soft large bore fuel hose will work (for a while) If the length from pump to heater is short it will work for longer. The issue is this is not like a normal internal combustion motor with a carburettor, more like a fuel injected motor where the fuel is injected into the engine. In this case into a glow plug atomisation screen to start the heater and then into a big burner atomisation screen to run the heater. (See how far you would get using soft fuel hose to car engine injectors) The diesel must be squirted into these screens for atomisation. Soft fuel hose absorbs the fuel pulses, which causes lack of atomisation, which then causes carbon formation, which causes restriction to fuel passage, which causes more carbon, which causes more restrictions, causing more carbon etc. If the fuel delivery is short and you were only supplied with cheap transparent plastic fuel hose and can't source hard nylon fuel hose, at the very least buy some quality automotive fuel hose. Cheers. JMcK
Wow. John clearly demonstrates such a comprehensive understanding of these systems both in theory and in practice, evidently from many years of experience and critical thought. Whilst there are many videos simply documenting an amateur install, these videos establish a knowledge of the core principals. It is very enabling, educational and such a great opportunity to learn more deeply about ubiquitous systems and reduce failure in these types of components.
Bruce Argyle Hi Bruce, there are a number of online sellers. Search hard nylon fuel hose for Eberspacher diesel heater. I don't like to list suppliers in the description as sellers come and go. The last supplier I bought hose from is no longer there. I just did a quick search to get you started. See below. www.ebay.com.au/itm/Diesel-Heater-Nylon-Fuel-Line-OD5mm-ID1-5mm-7m-/333785075903?_trksid=p2349624.m46890.l49292 Cheers. JMcK
Bruce Argyle Hi Bruce, The ID is not so critical, 1.5 mm to 3 mm ok. Probably 2 mm ID would be ideal. It is “hard” part that matters. The pump puts out pulses (squirts) of fuel, and a soft fuel hose on the delivery side of the pump absorbs these pulses making the fuel delivery to the heater less efficient. The outer diameter does not really matter, but thicker (stiffer) is preferable to thinner. Cheers. JMcK
I can’t tell you how much I appreciate you taking the time to share these videos! You’re the only dude out there with proper videos on these Chinese heaters. Thank you!
For Canadians I found certified fuel rated hose 3/32" (2.38mm) ID x 3/16"OD, 100psi (690kPl, 9bar)) at Home Debit, . It's in the plumbing department with the white nylon hose. It's easier to bend then the nylon hose and wont kink, but the material is far less compressible than the cheap soft hose that come with most diesel heaters. Made by Canada Tubing Products, part # SUFD10, it was less than $10 for 10' (3m). I tried heating the line to see if it would slip on, it won't, so you will still have to get attach the same way as in John's excellent videos
Hi Mark, we can't get that here, but I can find something similar on Amazon - www.amazon.ca/Platic-Poulan-Craftsman-Weedeater-Mower/dp/B0CZDRVGFS/ref=sr_1_2?dib=eyJ2IjoiMSJ9.p0ynkzovCTeoMaDVfjVs92vWBI7i6YPHCotAYP4y6yL5o3hEEYL5g1H8C7r90yepn7JgXPp8pleqRfPJEEDh7CwQz-Ntwx_gOLynfWjQ5Xwk0SLGVuOhOzUNp9z6MhgR8YEJGIIa1MC88fbrGFn1HmvufURiL53XTZEsWHyj2z0IzaYS7ZGFOKYGanDQbm1lyxknhyUNfy20-JOvhx5sg6x-pwLQCgWsX-9DwlkQJWbgBG3Kogm2HoKXrQh7QgK9dXaLCNwOhyS69LQSxusTgQ6-ePBnmBV4BSQkEby3q3U.GBxsemIddPMRlQfvnPKHzBFhinINBsXwl8sMRiznngk&dib_tag=se&hvadid=605318916377&hvdev=c&hvlocphy=9198475&hvnetw=g&hvqmt=e&hvrand=3299220485140925718&hvtargid=kwd-325786320843&hydadcr=10441_13533794&keywords=3%2F32+fuel+line&qid=1724611236&sr=8-2 Would that work?
I never considered the hydrostatic pressure aspect of the fuel delivery line but makes a lot of sense now why you'd want to use the 'hard line'. My heater is coming in Saturday for my cargo trailer conversion and after watching your videos I'm confident in installing it correctly! Thanks John!
I am a lady (so ignorant as far as how things work mechanically) and have been pulling my hair out trying to instal the heater in my caravan with badly translated instructions and worse illustrations. I had thought the supplier had sent the wrong fuel line - the hard type that did not fit the fittings, so I went out and bought the bigger soft fuel line. Have attached it all but still have to do the exhaust etc. Thank heavens for this very explicit video. I will now have to replace all of the fuel line with the original supplied, especially now I know how to join to the fitting. I have watched quite a few videos trying to get some insight as to installation and none go into enough detail. Thank you so much.
Hi Carol, Thank you for the feedback. It is generally ok to have the soft fuel line on the intake side of the pump, provided it is of a short distance. But you really need the narrow bore hard nylon on the outlet side of the pump. Good luck with your install. When set up right, these heaters give wonderful dry heat for those cold winter days. JMcK
You are an excellent teacher! You teach the "how" and the "why" which empowers your viewers to figure out the best way to install their heaters for their particular situation. Cheers!
Thanks for all the videos. At first I thought it was an overkill to do it so thoroughly, but I've watched most of them and they were really interesting and eye opening to the obvious truths :) Definitely cleared all the doubts I had before instaling my unit. Best regards from Poland!
I would have never thought this inexpensive heater would be so well engineered needing so much attention during the parts selection and subsequent installation. Your video series on this device is saving me money and saving money is my priority in life. Hand salute!!
Thank you John !! I am so very happy with your videos, learned so much! One hint for users who are thinking (like me) about installing the so called "silent pump" by james browning-smith: This pump is a better "sucker" than the standard issue noisy model, so that the pump should be mounted near the heater - the setup is: fuel tank - filter - longer part of the fuel line - pump - short fuel line - diesel heater.
One of the most informative, comprehensive and demonstrative TH-cam vids I’ve ever seen. Thank you John you are an Aussie gem. This to me is what TH-cam is all about. Education from people who (obviously) know what they’re talking about. John if I see you in the road I owe you a beer mate. Cheers. Pete
Hi Peter, I received an email notification from TH-cam where you were having trouble priming the fuel line, but when I went to the site your post had disappeared. Did you remove it or has it gone into the cloud somewhere. If you did not remove it can you please post it again, or email me at johnmck47@outlook.com. JMcK
Thanks for all these helpful videos! I've just purchased my first heater and have been installing it into a portable box for camping with our rooftop tent. I think I will have done everything twice by the time I'm done with this build because I didn't take the time to watch all your videos before I got started. Thankfully, I haven't been in a rush so I can fix the way I ran the fuel piping before running the system. In case anyone is interested, I just bought a Vevor 2kW unit (Dec 2021) and it came with the smaller gauge nylon (preferred) tubing and some rubber hose for the connections.
We are fortunate to have someone as talented as you providing this priceless information on the intricate details of what looks like a purely simple system. I can’t imagine the amount of time you must have spent to produce these videos 🤔 Certainly the data shipped with these units is inadequate, hard to interpret at best and flat dangerous at worst. As a retired Cat diesel mechanic, I thought I knew all I needed to know for such a simple device, and in fact, I had no issues with my shop workspace installation, but am thinking of your attention to detail on butting the small id rigid tubing within the soft hose connections to prevent an accumulator effect, cavitation etc. Although I was careful, I fell short of verifying all those points and think I will go over my fuel delivery system to make sure it is in optimum shape. Even thinking of doing a micro and I do mean “micro” bevel at the hard line cuts. As I said, my machine is performing very well, but with such tiny flow rates everything must be very precise for a clean efficient trouble free burn. I have my unit mounted high in my shop and the fuel tank is low as is the filter and pump, but I’m asking the dosing pump to lift the fuel straight up seven feet or a little over two meters, and while it’s working fine now ; I should probably change that for the long haul. Thanks so much for the great information! “💡”Have you ever thought of contracting with these Chinese manufacturers to write a proper discernible installation/troubleshooting manual? Cheers 🍻👍
Hi Siskyiou, thank you for the feedback. I think bevels are not necessary, but a 2 m push for the pump is right on the limit. If your heater is working well with no smoking I would leave it be. I would love feedback on how the pump performs at that hight. J
Hi Mr Si. Reading this again, I tend to think your proactive thoughts may prevent issues with your heater in the future particularly as you are asking a lot of the little dosing pump. Re the manuals, the Chinese have copied much of the genuine Eberspacher Manual, from German to Chinese and then appear to translate from Chinese to English. The English version of the Eberspacher D4 manual is well worth reading.
Hi John McK 47, I’ve verified the the plastic fuel line is butted at the tank, filter, pump and the input at the main unit but did not take the time to micro bevel the tubing as the way I cut it didn’t smash the tubing. I was however inaccurate in my fuel lift estimation as it is only 5.5’ a bit under 2 meters and the pump is gravity fed at fuel tank levels above 1/3. I’ve got 8 hours of run time and everything is looking good. Thanks for the information on the OEM manual, I will be looking into that🤓 Oh, and I sprung for the “8 kw unit” because of the type of space I’m heating and of coarse now know that it’s really a 5 kw. For the extra $40 dollars I got a fancy fake carbon fiber paint job ha ha🙃 Live and learn, but I’m happy with its performance just the same.
Great video mate, thanks for the advice. I have just bought a heater and was going to use a better quality rubber fuel line instead of the nylon. You saved me some dramas!!
Hi Andy, You can use quality fuel hose from tank to pump to eliminate all the joiners. Remember this distance needs to be short. You can also use quality fuel hose after the pump for short runs, 1m to 2m. Anything over that you really need to use the small bore hard nylon tubing. Good luck. JMcK
Thanks for that😊 I plumbed mine up last night with 3/16 fuel line it's only about 1m from pump to heater goes around a few corners of the caravan chassis but I put my pump facing downhill? That's what everyone else says? My tanks bottom is on the same level as heater (on van floor) but pump and filter are under van . Total hose used was 1.9m but I have about .5 to filter then .3 to pump. Do you think I should replace from pump to heater with the nylon supplied and change pump angle? Thanks Darren
Thank you soo much for this video I was experiencing the E 10 error on my Chinese Diesel heater, which was installed with the supplied 5m inner pipe. Changed to the Webasto nylon pipe 5mm outer and 2mm inner which I got off Ebay. After priming It started first time. You're a star for putting this video together and sharing your obvious immense knowledge.
I finally pulled the trigger and bought a diesel heater. I received my heater today and was annoyed with the " wrong size hose" that was supplied. I started looking at larger bore hose, but decided to revisit your channel as I've been here before. After watching Part 11, I am now educated on the fuel delivery aspect and thankful for your help. Who would have thought 2mm's along with material could make such a difference. Thanks for the awesome information John.
@@johnmck1147 Hi. John . i´m from Germany and are Diesel is as clean as in the rest of the world ;-) but i think the reason why the orignal German diesel heater only have that tiny filter installed is becouse they are mainly made for cars and the diesel comes in taht case from the car tank .. in that case the car has a filter systen wich is allready installed by the car manufactor. and thats why there seems no need for a nother big filter system Kind regards Willi
Thanks John as a retired brit trucker living in the USA and boondocking, i had trouble with a worn pump although not more than a couple of weeks use,i started from the fuel tank checked the flow downhill and flat,and checked joints ends of pipes,got a puff of smoke once,but as soon as i put a new pump on, no more problems !!! I guess now i know for sure the fuel flow is good. Thank you for your videos a great source of info. I still had a piece of the fue line they used in the 80's in my toolbox black plastic 2mm inside but twice as thick as what you get now.
@@johnmck1147 yes,i got larger model filter a couple of inches from the fuel supply.great when it works correctly,using it right now (26f outside). I love my night heater Thanks J
@@johnmck1147 checked my fuel filter,after a couple of days use,very fine (sand) grit in there,most likely what tore up my previous pump. Thanks again John
Thanks so much, you've solved all my problems. I'm on my third pump after returning the first two because they were creating air bubbles! Just installed nylon line and working well so far :)
So very very helpful I was stumped when I saw the small hose supplied and thought I’d be duped But you very succinctly explained it all in an easy straight forward way. Saved the day Cheers
Thanks for rigging up the models, mate. Really gives a solid understanding of what's going on in these things. Until i watched this vid, i knew the diesel went in the hole and made heat come out. I've got a much better awareness of what's going on in my heater now. Thanks!
Best video explaining the details and subtleties of fuel delivery and ignition for diesel heaters and the importance of the component parts working properly together. Well done !!
Great insight on the fuel delivery and dosing into the atomizer. Wow, your explanation is so in depth and detailed with real lab work. I absolutely appreciate you sir.
This is AMAZING! I have a LARGE bubble permanently stuck on the bottom of my VEVOR heater (inside his case). Lines are soft, so that's why the bubble is there. The heater works very well but now I suppose it can work even better. Will upgrade and test ASAP, thank you :)
I was thinking to install heater this weekend, but after I've watched your video, nylon pipe has been ordered and I'll fit this when new fuel line arrives. Many thanks
Installing mine as I watch, keep coming in for a re-cap from my notes I took from these videos a couple of month ago. Brilliant information - thanks again John.
@@johnmck1147 I have aspergers and need to know things are done to the absolute the best they can be..... No short cuts, no guessing or making do, solid factual scientific and practically tested methods where if followid..... Will get the best results. You videos give me the best platform to accomplish this. Wonderful.
Thank you very much John for taking the time to help us. Your videos are invaluable for those like me they face the installation of these Chinese heater. Most of these are delivered without instruction or unreadable translation from chinese to english. Forever your debtor.
I can't tell you how much I appreciate all of the wisdom in your videos. I would have just dropped one in my van and made at least 3 mistakes and then bi!ch about the crappry heater. Thank you very much! Soo much info. Even just your side comments are so informative and insightful. Thanks for all the hard work and time making these videos. I would pay for all this info. Maybe it could be a book on Amazon?
THANK YOU SIR ! For your hard work and knowledge of diesel heaters. I am still watching your series. I feel you are the best provider of this needed information.
i just got a heater and installed it in my vw transporter, now watching your videos for tips and preventative measures, great that youve taken so much time and made the effort, all the best from cold and rainy uk
Great high quality video from distance to close up fine detail focus. I consider myself lucky in finding such quality detailing of proper installation as well as to why the work has to be done properly and as to the failures that happen when there is not enough information from the factory! THANKS!!!
GREAT info. The manual in my heater box did NOT say anything about the fuel line. Thank you very much for explaining the whole process so clearly. I've been trying to get this thing running for a few days now!!! So tmrw I should get some heat out of it!!! Tks again.
Brilliant. You can't beat old school who know their onions! I think you've saved me a lot of tears showing the shortcomings of the Chinese copy, which I'll be fitting shortly to the brother in laws' motorhome. I was going to tap into the fuel tank auxiliary if it has one and use copper brake pipe as I have plenty and the flaring tool, nuts and connectors but your suggestion of 2mm nylon might be a better way to go. Many thanks.
Good explanation. I really like guys like you. When I was a kid, there where guys like you everywhere (no offense), guess I took it for granted. But now? You're a treasure and getting rarer by the day. Glad you're making videos!
Hi John, thanks for your great videos. I have just installed a 8 kw Chinese heater in a workshop and it works great. My heater came with a remote control and a small online fuel filter which is a lot better than the tiny filters which comes with the D2 Airtronic. It is a good idea to run the heaters at a high setting regularly to keep the combustion chamber clean. I think our diesel in Western Australia is pretty low quality as I travelled over east for several months, running the heater every day for about 8 hours with no problems and clean combustion, however, once back home it only took about 2 weeks to soot up the combustion chamber. Adding some kero and running the heater hot does cleans the soot a bit but usually I have to replace the screen in the ignition changer. I like your removal tool! Another problem I have encountered is a dust build up on the flame/ heat sensor mounted on the combustion chamber which can cause an error code. I found that the shortest length of the exhaust pipe possible will give longer periods between services, our diesel again. I have an Edith Diagnostics adapter for my Espar D2 heaters to work the error codes but have not had to use it much as I can usually figure out what causes the faults. Thanks again for you information. They are great space heaters,
Hi Peter, thank you for your detailed feedback. I agree with you about the variance of diesel quality and the need to keep the exhaust short or go larger. You also need to keep the combustion air intake short, or go larger. Glad you like my screen removal tool, but have you managed to source the very rare screen insertion tool? Cheers, JMcK
answered my question clearly. i wanted to go with a standard flexible fuel line that would fit the barbed fittings. I figured there was a reason for the small, hard tubing. Answered perfectly! thanks!!
Hi TSA, I use the standard fuel line for the pick up side of the heater. Ie Tank to shut off valve to filter to fuel pump. That removes a lot of the joins. I only use hard nylon on the delivery side of the fuel pump. Ie pump to heater. More info in motorhome videos. Cheers. JMcK
Some great engineering principles explained here. I bought a Vevor® "square brick" heater box but it didn't last long. Turns out the hard tube inside had a few factory installed coils so the bubbles were collecting up top and the atomizer screen was all carboned up. A thorough cleanout and rerouting the tubes fixed it good! So if you buy any of the box units take the cover off and inspect the tubing!
Man this is great! Just ordered one a few minutes ago. Bet mine will have the flexie line. If we hadn't had seen this video we wouldn't have had a clue. Tho I have worked around hydraulics since being a kid and understand the principal of air compressing , but when a product is supplied with something , you usually just go with it. But Thank You again 👍👍👍👍👍
Hi Phil It is ok to run normal fuel hose (in most installs) from tank to filter to pump. But you should only run the narrow bore hard fuel line from the pump to the heater. The normal large fuel hose will still work if the run from pump to heater is very short and lacks loops where large bubbles can form. But you will have maintenance issues as the hose will absorb the pressure pulses and you won't get proper atomisation in the burner. JMcK
I will be fitting a diesel air heater to the Campervan I'm fitting out . John , thank you very much for the information that you are sharing . You're a wealth of knowledge !
Mate, thanks. This is so clear and easy to understand. Unlike the instructions in the box, which don't say much anyway and what they do say is not really in Engrish. Could have guessed my way through most of it, but probably would have spend the next couple of months working out what I did wrong! Tidy.
Fantastic series of videos, thank you for taking the considerable time it takes to produce them. So much bullshit and absolute guesses are sprouted out there by the uninformed. It's an absolute pleasure to watch someone who obviously knows his stuff about these units.
Thank you! I had my heater fitted for me and have had fuel problems since - he used a flexible hose! I will swap it today. Appreciate you taking time to explain this
Thanks John you answered every question I needed to know, I thought I had ordered the wrong fuel line, because it was to thin after watching your video I was jumping for joy many many thanks, big thumbs up.
His advice and requirements are absolutely correct. Go to the eberspacher website and follow their install specs if you bought a Chinese diesel heater and save yourself a lot of time and aggravation
What an excellent job you have made of this series of videos, working my way through them and each and every one is a gold mine of information, thank you very much for taking a significant amount of your time to share your knowledge and experience. All the best
Thank you John for your very, authoritative, informative, and understandable videos. I very much appreciate your efforts. May God Bless you indeed. Dale
John I try to tell this to the people on our forum nearly daily with not much luck , Now I can say have a look at the video's from the "Goeroe" of the Chinese Heater's Mr John McK 47 . Thank you so much for your video's , now they can see what I try to tell them . Thanks Sir, Greetings from Belgium
John, this is the only video of yours I've watched (yet!), But it is awesome. Thank you so much for taking the time to do this! If it wasn't for you making such comprehensive videos, many of us users would struggle to get these things working properly. Thank you!
Thank you so much for your video. Your proper and in-depth explanation helped me a lot to sort the problems a had with my heater!! So thank you very much!!
Hi John, great run down. I was about to go and buy some large diameter fuel line as I couldn't work out how the small stuff was supposed to fit. You've just saved me money and no doubt some frustrations. Thanks.
Hi Andrew, you can run standard fuel hose from tank to pump on the suction side, but should only use hard nylon small bore tube on the delivery side of the pump. JMcK
John I genuinely enjoyed your video. All the detail along with the props you used and even going as far as setting up the hose display was excellent. Thank you for putting all the time that you did in making this video. I am looking forward to seeing some of the other videos you've uploaded. Best wishes!
Hey John "Great Vid" I've just bought a Diesel Heater and realised the vynil hose needed an upgrade, my heater now runs very nicely with 2mm nylon hose. I lived in Vic between 04 to 08 and listerning to youre Magpies made me smile, tho I don't miss the Butcher bird's calling at 5am.. take it easy.....
John, Thank you so much for providing these great video's on the diesel heaters. I feel so much more confident that I will be able to set my heater up so I am able to use it ice fishing here in Manitoba, Canada. You have done a great job on these video's my son and I thank you for your efforts.
hey john. Thanks for all of your helpful videos. I'm sure you have become a pillar of hope for many people around the globe, just looking to keep a little warmer. Anywho... I followed your directions on assembling the fuel delivery system in the proper way. I have a 5kw(8kw) installed in a camper-van. ( i know this could be overkill but i had no idea when i purchased it), and i have the fuel delivery components underneath the van, My heater came with the hard nylon hose, but i still protected it by sliding it inside a larger clear hose, just as you mention in the video. I used proper black fuel hose coming from the tank, into a valve, then into the filter, and then into the pump, just as you mention in the video. I fired it up yesterday for the first time, and it seems to run great right off the hop, and I had it on for a solid 6 hours with no problem. So following your advice I had it on low most of the time, and then before shutting off i cranked it up to high to burn off any carbon deposits. It is after this that i noticed that there are fuel leaks at the connection points of the filter, the delivery side of the pump, and also where the line meets the heater!!. No error codes however, even after running it again, so it must be getting proper fuel. Im 99 percent sure the hard vinyl hoses is butted up to the inlets, and im 99 percent sure ive tightened the hose clamps down securely. I'm not exactly sure what i did wrong or what i should do next? Can the clamps be overtightened? Someone suggested i change the hose clamps for the pressure clamps, but this will be a challenge to access the one right beneath the heater. Do you think that the sudden change from lowest setting to highest setting created enough of a spike in fuel pressure to create these leaks? and if this is so, how can i burn off the carbon? what temp would it need to be turned up to if not the max 35 degrees? im afraid to crank it up again. Any insight would be greatly appreciated. Cheers
Hi Bruce, Thanks for the feedback. Ref the clamps. You do not say what clamps you used. Please have another look at the motorhome videos re clamps. If you use screw type clamps on the nylon/rubber joiners you can actually creat a leak if clamp too tight. Now re the carbon removal. If your install is gold standard with very few restrictions in the combustion air inlet and the exhaust, you will have few carbon build up issues, and a med burn run now and then should be sufficient. I run the boat heater mostly on low, and at the end of season I give it 15 minutes on medium and I haven't had to service heater in 10 years. But my install has absolute min burner restrictions. However if you have twists and turns in the exhaust, same for the combustion air inlet, and add in dirty filter to boot, you will have poor a combustion burn, and you will get excessive carbon deposits. Your choice, if you can get by running heater on low and med, but you really do not want fuel leaks in your install. I hope this helps a little. JMcK
John McK 47 Thanks for the thoughtful response. I’m using the screw on clips that came with the heater. Based on your response... I’m assuming that perhaps I over tightened them . If I have created leaks by overtoghtening... do u think loosening off a bit would remedy this, or did I create a crack in the connectors?
Bruce Petracek Hi Bruce, it is a little hard fo me to comment without actually seeing your set up. Yes, you can creat a leak by overnighting those worm clamps on small diameter hose. If your nylon hose easily slides into the rubber connector, you will have a leak that can't be sealed by a clamp. You could try some silicone gasket sealant or similar to seal the hose. Have you seen the motorhome videos. I talk more about this there. Cheers. JMcK
How did I not think of that by my self... larger diameter, more volume to pull... larger volume, bubbles joyn... THANK YOU, not just for here but also elsewhee, moment of AHAAAAAA !!!!
Hi John, Just coming across your videos having just installed a 5Kw unit into my caravan ready for the winter. Very informative regarding the fuel hose and delivery system, since I have only once since installation a week ago had a successful run of the heater. Suffice to say, mine came with the poor vinyl large bore fuel line, which I see now I need to replace from the pump. (luckily I have plenty of the 4mm hard bore hose in my workshop). Another issue is that in the caravan, I am very limited in installation location of heater and fuel tank, such that without putting the pump outside / under the van on the chassis, it's near impossible to get a steady incline up to the feed point of the heater. What happens currently is the heater will not properly ignite, makes a very impressive smoke generator with clouds of white diesel vapour!! It's good to see from your video now how I can hopefully resolve my problems just changing the feedline! Thanks for the great info in your videos. ;)
Hi Tim, Good quality automotive hose is fine for the suction side of the pump, but on the delivery side of the pump to heater you should use narrow bore hard nylon fuel hose. JMcK
I have tried it both ways and the supplied soft large bore fuel line did work, however the small hard line as described by John did work MUCH better!
It's little nuggets of knowledge like this that should make John's entire series on these heaters mandatory for anyone purchasing one of these heaters. You owe it to yourself to watch this incredibly well researched series. Tons of knowledge in each episode.
Thank you John for all of the hard work that these videos must have entailed!
Hi 74 Willy,
First thanks for your kind comments.
Yes, the soft large bore fuel hose will work (for a while)
If the length from pump to heater is short it will work for longer.
The issue is this is not like a normal internal combustion motor with a carburettor, more like a fuel injected motor where the fuel is injected into the engine. In this case into a glow plug atomisation screen to start the heater and then into a big burner atomisation screen to run the heater. (See how far you would get using soft fuel hose to car engine injectors)
The diesel must be squirted into these screens for atomisation. Soft fuel hose absorbs the fuel pulses, which causes lack of atomisation, which then causes carbon formation, which causes restriction to fuel passage, which causes more carbon, which causes more restrictions, causing more carbon etc.
If the fuel delivery is short and you were only supplied with cheap transparent plastic fuel hose and can't source hard nylon fuel hose, at the very least buy some quality automotive fuel hose.
Cheers. JMcK

Hi Bruce,
The ID is not so critical, 1.5 mm to 3 mm ok.
Probably 2 mm ID would be ideal.
It is “hard” part that matters. The pump puts out pulses (squirts) of fuel, and a soft fuel hose on the delivery side of the pump absorbs these pulses making the fuel delivery to the heater less efficient. The outer diameter does not really matter, but thicker (stiffer) is preferable to thinner.
Cheers. JMcK
I can’t tell you how much I appreciate you taking the time to share these videos! You’re the only dude out there with proper videos on these Chinese heaters.
Thank you!
Thanks for the positive feedback Than. JMcK
John , thanks for the information.
Question , can i place my diesel tank on the roofrack of my van ?
To much pressure ?
For Canadians I found certified fuel rated hose 3/32" (2.38mm) ID x 3/16"OD, 100psi (690kPl, 9bar)) at Home Debit, . It's in the plumbing department with the white nylon hose. It's easier to bend then the nylon hose and wont kink, but the material is far less compressible than the cheap soft hose that come with most diesel heaters. Made by Canada Tubing Products, part # SUFD10, it was less than $10 for 10' (3m). I tried heating the line to see if it would slip on, it won't, so you will still have to get attach the same way as in John's excellent videos
Hi Mark, we can't get that here, but I can find something similar on Amazon - www.amazon.ca/Platic-Poulan-Craftsman-Weedeater-Mower/dp/B0CZDRVGFS/ref=sr_1_2?dib=eyJ2IjoiMSJ9.p0ynkzovCTeoMaDVfjVs92vWBI7i6YPHCotAYP4y6yL5o3hEEYL5g1H8C7r90yepn7JgXPp8pleqRfPJEEDh7CwQz-Ntwx_gOLynfWjQ5Xwk0SLGVuOhOzUNp9z6MhgR8YEJGIIa1MC88fbrGFn1HmvufURiL53XTZEsWHyj2z0IzaYS7ZGFOKYGanDQbm1lyxknhyUNfy20-JOvhx5sg6x-pwLQCgWsX-9DwlkQJWbgBG3Kogm2HoKXrQh7QgK9dXaLCNwOhyS69LQSxusTgQ6-ePBnmBV4BSQkEby3q3U.GBxsemIddPMRlQfvnPKHzBFhinINBsXwl8sMRiznngk&dib_tag=se&hvadid=605318916377&hvdev=c&hvlocphy=9198475&hvnetw=g&hvqmt=e&hvrand=3299220485140925718&hvtargid=kwd-325786320843&hydadcr=10441_13533794&keywords=3%2F32+fuel+line&qid=1724611236&sr=8-2
Would that work?
Thanks! Where did you find all your other fittings, exhaust hosing etc
This guy is AWESOME!!!! We need more people in this world as passionate about detail as this man!
Wow! Thanks for the positive feedback Calidrummin. JMcK
I never considered the hydrostatic pressure aspect of the fuel delivery line but makes a lot of sense now why you'd want to use the 'hard line'. My heater is coming in Saturday for my cargo trailer conversion and after watching your videos I'm confident in installing it correctly! Thanks John!
I am a lady (so ignorant as far as how things work mechanically) and have been pulling my hair out trying to instal the heater in my caravan with badly translated instructions and worse illustrations. I had thought the supplier had sent the wrong fuel line - the hard type that did not fit the fittings, so I went out and bought the bigger soft fuel line. Have attached it all but still have to do the exhaust etc. Thank heavens for this very explicit video. I will now have to replace all of the fuel line with the original supplied, especially now I know how to join to the fitting. I have watched quite a few videos trying to get some insight as to installation and none go into enough detail. Thank you so much.
Hi Carol,
Thank you for the feedback. It is generally ok to have the soft fuel line on the intake side of the pump, provided it is of a short distance. But you really need the narrow bore hard nylon on the outlet side of the pump.
Good luck with your install. When set up right, these heaters give wonderful dry heat for those cold winter days. JMcK
You are an excellent teacher! You teach the "how" and the "why" which empowers your viewers to figure out the best way to install their heaters for their particular situation. Cheers!
Wow Tim, thank you for those positive comments.
Happy New Year. JMcK
Wow Tim, thank you for those positive comments.

John I avoided several mistakes watching your video! Thank you very much, you made my day.
Hands down the best informational video for these heaters on TH-cam.
Thank you . JMcK
This is why TH-cam was made useful & popular - helpful explainer and how-to videos by knowledgeable people. Thank you.
Thanks Jacob. JMcK
Thanks for all the videos. At first I thought it was an overkill to do it so thoroughly, but I've watched most of them and they were really interesting and eye opening to the obvious truths :) Definitely cleared all the doubts I had before instaling my unit. Best regards from Poland!
Thank you for the feedback. JMcK
I would have never thought this inexpensive heater would be so well engineered needing so much attention during the parts selection and subsequent installation. Your video series on this device is saving me money and saving money is my priority in life. Hand salute!!
I am glad I was of some help to you. JMcK
Love how you did a full breakdown of the unit, it was really interesting and helpful. Most other video's don't go this in depth. Thanks!
Thanks for the positive feedback. JMcK
Thank you John !! I am so very happy with your videos, learned so much! One hint for users who are thinking (like me) about installing the so called "silent pump" by james browning-smith: This pump is a better "sucker" than the standard issue noisy model, so that the pump should be mounted near the heater - the setup is: fuel tank - filter - longer part of the fuel line - pump - short fuel line - diesel heater.
One of the most informative, comprehensive and demonstrative TH-cam vids I’ve ever seen. Thank you John you are an Aussie gem. This to me is what TH-cam is all about. Education from people who (obviously) know what they’re talking about. John if I see you in the road I owe you a beer mate. Cheers. Pete
Hi Peter, I received an email notification from TH-cam where you were having trouble priming the fuel line, but when I went to the site your post had disappeared. Did you remove it or has it gone into the cloud somewhere. If you did not remove it can you please post it again, or email me at johnmck47@outlook.com. JMcK
Thanks for all these helpful videos! I've just purchased my first heater and have been installing it into a portable box for camping with our rooftop tent. I think I will have done everything twice by the time I'm done with this build because I didn't take the time to watch all your videos before I got started. Thankfully, I haven't been in a rush so I can fix the way I ran the fuel piping before running the system. In case anyone is interested, I just bought a Vevor 2kW unit (Dec 2021) and it came with the smaller gauge nylon (preferred) tubing and some rubber hose for the connections.
Thanks for the feedback Kevin.
Happy New Year. JMcK
We are fortunate to have someone as talented as you providing this priceless information on the intricate details of what looks like a purely simple system. I can’t imagine the amount of time you must have spent to produce these videos 🤔 Certainly the data shipped with these units is inadequate, hard to interpret at best and flat dangerous at worst. As a retired Cat diesel mechanic, I thought I knew all I needed to know for such a simple device, and in fact, I had no issues with my shop workspace installation, but am thinking of your attention to detail on butting the small id rigid tubing within the soft hose connections to prevent an accumulator effect, cavitation etc. Although I was careful, I fell short of verifying all those points and think I will go over my fuel delivery system to make sure it is in optimum shape. Even thinking of doing a micro and I do mean “micro” bevel at the hard line cuts. As I said, my machine is performing very well, but with such tiny flow rates everything must be very precise for a clean efficient trouble free burn. I have my unit mounted high in my shop and the fuel tank is low as is the filter and pump, but I’m asking the dosing pump to lift the fuel straight up seven feet or a little over two meters, and while it’s working fine now ; I should probably change that for the long haul. Thanks so much for the great information! “💡”Have you ever thought of contracting with these Chinese manufacturers to write a proper discernible installation/troubleshooting manual? Cheers 🍻👍
Hi Siskyiou, thank you for the feedback. I think bevels are not necessary, but a 2 m push for the pump is right on the limit. If your heater is working well with no smoking I would leave it be. I would love feedback on how the pump performs at that hight. J
Hi Mr Si. Reading this again, I tend to think your proactive thoughts may prevent issues with your heater in the future particularly as you are asking a lot of the little dosing pump.
Re the manuals, the Chinese have copied much of the genuine Eberspacher Manual, from German to Chinese and then appear to translate from Chinese to English. The English version of the Eberspacher D4 manual is well worth reading.
Hi John McK 47, I’ve verified the the plastic fuel line is butted at the tank, filter, pump and the input at the main unit but did not take the time to micro bevel the tubing as the way I cut it didn’t smash the tubing. I was however inaccurate in my fuel lift estimation as it is only 5.5’ a bit under 2 meters and the pump is gravity fed at fuel tank levels above 1/3. I’ve got 8 hours of run time and everything is looking good. Thanks for the information on the OEM manual, I will be looking into that🤓 Oh, and I sprung for the “8 kw unit” because of the type of space I’m heating and of coarse now know that it’s really a 5 kw. For the extra $40 dollars I got a fancy fake carbon fiber paint job ha ha🙃 Live and learn, but I’m happy with its performance just the same.
Siskiyou Woodsmann, Sounds good. The height is a bonus as well. Enjoy the dry heat. J
You're a bloody LEGEND! :)
I remember trainers that were like you when I worked photocopiers. Natural teachers. Thank you Sir.
Thank you Mike. JMcK
Great video mate, thanks for the advice. I have just bought a heater and was going to use a better quality rubber fuel line instead of the nylon. You saved me some dramas!!
Hi Andy,
You can use quality fuel hose from tank to pump to eliminate all the joiners. Remember this distance needs to be short.
You can also use quality fuel hose after the pump for short runs, 1m to 2m. Anything over that you really need to use the small bore hard nylon tubing.
Good luck. JMcK
Thanks for that😊 I plumbed mine up last night with 3/16 fuel line it's only about 1m from pump to heater goes around a few corners of the caravan chassis but I put my pump facing downhill? That's what everyone else says? My tanks bottom is on the same level as heater (on van floor) but pump and filter are under van . Total hose used was 1.9m but I have about .5 to filter then .3 to pump. Do you think I should replace from pump to heater with the nylon supplied and change pump angle? Thanks Darren
Thank you soo much for this video I was experiencing the E 10 error on my Chinese Diesel heater, which was installed with the supplied 5m inner pipe. Changed to the Webasto nylon pipe 5mm outer and 2mm inner which I got off Ebay. After priming It started first time. You're a star for putting this video together and sharing your obvious immense knowledge.
Thanks for the feedback TA. JMcK
Great work! Thanks so much for these vids. Plain and simple to understand.
Thanks Robbie. JMcK
I finally pulled the trigger and bought a diesel heater. I received my heater today and was annoyed with the " wrong size hose" that was supplied. I started looking at larger bore hose, but decided to revisit your channel as I've been here before. After watching Part 11, I am now educated on the fuel delivery aspect and thankful for your help. Who would have thought 2mm's along with material could make such a difference. Thanks for the awesome information John.
Thanks for the feedback Dforty. JMcK
Thanks for doing these videos!!!
Your welcome Patrick.
Your video's just saved my heater from being smashed with a hammer with frustration! Knowledge is key and thank you so much for sharing yours!
Oh dear Ian, you heater would not like that. I am glad I have been of some help. JMcK
You're a bloody LEGEND! :)
Wow! Thanks Trewin.
@@johnmck1147 Hi. John . i´m from Germany and are Diesel is as clean as in the rest of the world ;-)
but i think the reason why the orignal German diesel heater only have that tiny filter installed is becouse they are mainly made for cars and the diesel comes in taht case from the car tank .. in that case the car has a filter systen wich is allready installed by the car manufactor. and thats why there seems no need for a nother big filter system
Kind regards Willi
MC 11
Hi Willi, thank you for that info and feedback. Also my apologies for my wrong pronunciation of Eberspacher. JMcK
Thanks John as a retired brit trucker living in the USA and boondocking, i had trouble with a worn pump although not more than a couple of weeks use,i started from the fuel tank checked the flow downhill and flat,and checked joints ends of pipes,got a puff of smoke once,but as soon as i put a new pump on, no more problems !!!
I guess now i know for sure the fuel flow is good.
Thank you for your videos a great source of info.
I still had a piece of the fue line they used in the 80's in my toolbox black plastic 2mm inside but twice as thick as what you get now.
Hi Colin,,
Thanks for the info. Pleased things now ok.
I assume you have a good fuel filter in the line before the pump. JMcK
@@johnmck1147 yes,i got larger model filter a couple of inches from the fuel supply.great when it works correctly,using it right now (26f outside).
I love my night heater
Thanks J
👍
@@johnmck1147 checked my fuel filter,after a couple of days use,very fine (sand) grit in there,most likely what tore up my previous pump. Thanks again John

Thanks so much, you've solved all my problems. I'm on my third pump after returning the first two because they were creating air bubbles! Just installed nylon line and working well so far :)
👍
Just wanted to thank you for this excellent series. I actually installed an Eberspacher, but your wonderful videos were great 'enablers'. Many thanks.
Pleased you found them helpful Patrick. JMcK
Woah, who would have thought bigger line wasn't better!
Thanks John!
So very very helpful
I was stumped when I saw the small hose supplied and thought I’d be duped
But you very succinctly explained it all in an easy straight forward way. Saved the day

That was a great illustration rather than just talking and theory. Thanks for that.
Pleased you found it helpful Marty. JMcK
Thanks for rigging up the models, mate. Really gives a solid understanding of what's going on in these things. Until i watched this vid, i knew the diesel went in the hole and made heat come out. I've got a much better awareness of what's going on in my heater now. Thanks!
Best video explaining the details and subtleties of fuel delivery and ignition for diesel heaters and the importance of the component parts working properly together. Well done !!

Awesome John ! 6 hours in researching diesel heaters and this is the best quality advice so far . cheers
Hi Rob, thanks for your positive comments. JMcK
Thank you John this will save me a lot of time when I install my system! You are a great contributor to society sir!
Thank you for your kind words Hung. JMcK
This is AMAZING! I have a LARGE bubble permanently stuck on the bottom of my VEVOR heater (inside his case). Lines are soft, so that's why the bubble is there. The heater works very well but now I suppose it can work even better. Will upgrade and test ASAP, thank you :)
excellent video straight to the subject...people like you who make these videos are a Godsend...thank you
Brilliant explanation of complex concepts into a language that non technical people like myself can grasp. Well done John
Thanks for that positive feedback David. JMcK
I was thinking to install heater this weekend, but after I've watched your video, nylon pipe has been ordered and I'll fit this when new fuel line arrives. Many thanks

I have binge watched all your videos and slept on it.
I am sure it will be a well informed install now.👍
Thanks for the nice feedback Slade. JMcK
GREAT info. The manual in my heater box did NOT say anything about the fuel line. Thank you very much for explaining the whole process so clearly. I've been trying to get this thing running for a few days now!!! So tmrw I should get some heat out of it!!! Tks again.
👍
Brilliant. You can't beat old school who know their onions! I think you've saved me a lot of tears showing the shortcomings of the Chinese copy, which I'll be fitting shortly to the brother in laws' motorhome. I was going to tap into the fuel tank auxiliary if it has one and use copper brake pipe as I have plenty and the flaring tool, nuts and connectors but your suggestion of 2mm nylon might be a better way to go. Many thanks.
Good explanation. I really like guys like you. When I was a kid, there where guys like you everywhere (no offense), guess I took it for granted. But now? You're a treasure and getting rarer by the day. Glad you're making videos!
Not sure what to say here……😳
Would never have dreamt of such detail. Back to the workshop to butt up all those connectors, sheesh. And many thanks, again!
Your welcome John
Hi John, thanks for your great videos. I have just installed a 8 kw Chinese heater in a workshop and it works great. My heater came with a remote control and a small online fuel filter which is a lot better than the tiny filters which comes with the D2 Airtronic. It is a good idea to run the heaters at a high setting regularly to keep the combustion chamber clean. I think our diesel in Western Australia is pretty low quality as I travelled over east for several months, running the heater every day for about 8 hours with no problems and clean combustion, however, once back home it only took about 2 weeks to soot up the combustion chamber. Adding some kero and running the heater hot does cleans the soot a bit but usually I have to replace the screen in the ignition changer. I like your removal tool! Another problem I have encountered is a dust build up on the flame/ heat sensor mounted on the combustion chamber which can cause an error code. I found that the shortest length of the exhaust pipe possible will give longer periods between services, our diesel again. I have an Edith Diagnostics adapter for my Espar D2 heaters to work the error codes but have not had to use it much as I can usually figure out what causes the faults. Thanks again for you information. They are great space heaters,
Hi Peter, thank you for your detailed feedback. I agree with you about the variance of diesel quality and the need to keep the exhaust short or go larger. You also need to keep the combustion air intake short, or go larger.
Glad you like my screen removal tool, but have you managed to source the very rare screen insertion tool?
Cheers, JMcK
answered my question clearly. i wanted to go with a standard flexible fuel line that would fit the barbed fittings. I figured there was a reason for the small, hard tubing. Answered perfectly! thanks!!
Hi TSA,
I use the standard fuel line for the pick up side of the heater. Ie Tank to shut off valve to filter to fuel pump. That removes a lot of the joins.
I only use hard nylon on the delivery side of the fuel pump. Ie pump to heater. More info in motorhome videos.
Cheers. JMcK
Some great engineering principles explained here. I bought a Vevor® "square brick" heater box but it didn't last long. Turns out the hard tube inside had a few factory installed coils so the bubbles were collecting up top and the atomizer screen was all carboned up. A thorough cleanout and rerouting the tubes fixed it good! So if you buy any of the box units take the cover off and inspect the tubing!
👍
Man this is great! Just ordered one a few minutes ago. Bet mine will have the flexie line. If we hadn't had seen this video we wouldn't have had a clue. Tho I have worked around hydraulics since being a kid and understand the principal of air compressing , but when a product is supplied with something , you usually just go with it. But Thank You again 👍👍👍👍👍
Hi Phil
It is ok to run normal fuel hose (in most installs) from tank to filter to pump. But you should only run the narrow bore hard fuel line from the pump to the heater.
The normal large fuel hose will still work if the run from pump to heater is very short and lacks loops where large bubbles can form. But you will have maintenance issues as the hose will absorb the pressure pulses and you won't get proper atomisation in the burner. JMcK
Much appreciated John. Had issues this winter with carbon buildup. Buying a new heater and using hard nylon small bore fuel hose
I will be fitting a diesel air heater to the Campervan I'm fitting out . John , thank you very much for the information that you are sharing . You're a wealth of knowledge !
Hi Peter, pleased you found the videos helpful. JMcK
Mate, thanks.
This is so clear and easy to understand. Unlike the instructions in the box, which don't say much anyway and what they do say is not really in Engrish.
Could have guessed my way through most of it, but probably would have spend the next couple of months working out what I did wrong!
Tidy.
Thanks for the positive feedback Mr G. JMcK
Fantastic series of videos, thank you for taking the considerable time it takes to produce them.

This is insane you are a hero, you saved my winter 🥶 in the van
hey john. Thanks for all of your helpful videos. I'm sure you have become a pillar of hope for many people around the globe, just looking to keep a little warmer. Anywho... I followed your directions on assembling the fuel delivery system in the proper way. I have a 5kw(8kw) installed in a camper-van. ( i know this could be overkill but i had no idea when i purchased it), and i have the fuel delivery components underneath the van, My heater came with the hard nylon hose, but i still protected it by sliding it inside a larger clear hose, just as you mention in the video. I used proper black fuel hose coming from the tank, into a valve, then into the filter, and then into the pump, just as you mention in the video. I fired it up yesterday for the first time, and it seems to run great right off the hop, and I had it on for a solid 6 hours with no problem. So following your advice I had it on low most of the time, and then before shutting off i cranked it up to high to burn off any carbon deposits. It is after this that i noticed that there are fuel leaks at the connection points of the filter, the delivery side of the pump, and also where the line meets the heater!!. No error codes however, even after running it again, so it must be getting proper fuel. Im 99 percent sure the hard vinyl hoses is butted up to the inlets, and im 99 percent sure ive tightened the hose clamps down securely. I'm not exactly sure what i did wrong or what i should do next? Can the clamps be overtightened? Someone suggested i change the hose clamps for the pressure clamps, but this will be a challenge to access the one right beneath the heater. Do you think that the sudden change from lowest setting to highest setting created enough of a spike in fuel pressure to create these leaks? and if this is so, how can i burn off the carbon? what temp would it need to be turned up to if not the max 35 degrees? im afraid to crank it up again.
Any insight would be greatly appreciated.
Cheers
Hi Bruce,
Thanks for the feedback.
Ref the clamps. You do not say what clamps you used. Please have another look at the motorhome videos re clamps. If you use screw type clamps on the nylon/rubber joiners you can actually creat a leak if clamp too tight.
Now re the carbon removal. If your install is gold standard with very few restrictions in the combustion air inlet and the exhaust, you will have few carbon build up issues, and a med burn run now and then should be sufficient.
I run the boat heater mostly on low, and at the end of season I give it 15 minutes on medium and I haven't had to service heater in 10 years. But my install has absolute min burner restrictions.
However if you have twists and turns in the exhaust, same for the combustion air inlet, and add in dirty filter to boot, you will have poor a combustion burn, and you will get excessive carbon deposits.
Your choice, if you can get by running heater on low and med, but you really do not want fuel leaks in your install.
I hope this helps a little. JMcK
John McK 47 Thanks for the thoughtful response. I’m using the screw on clips that came with the heater. Based on your response... I’m assuming that perhaps I over tightened them . If I have created leaks by overtoghtening... do u think loosening off a bit would remedy this, or did I create a crack in the connectors?

Hi Bruce, it is a little hard fo me to comment without actually seeing your set up.
Yes, you can creat a leak by overnighting those worm clamps on small diameter hose.
If your nylon hose easily slides into the rubber connector, you will have a leak that can't be sealed by a clamp. You could try some silicone gasket sealant or similar to seal the hose.
Have you seen the motorhome videos. I talk more about this there.
Cheers. JMcK
Thank you so much , now I have learned how to set up my heater. I appreciate your knowledge.
@@Jay-k8t4n pleased you found the videos helpful..lJMcK
How did I not think of that by my self... larger diameter, more volume to pull... larger volume, bubbles joyn... THANK YOU, not just for here but also elsewhee, moment of AHAAAAAA !!!!
I’ve revisited this before I reroute my fuel line. Best info out there!
Thanks for the feedback Jetmelt. Hope videos are helpful. JMcK
Thank you for so detailed and valuable information.

Hi John, Just coming across your videos having just installed a 5Kw unit into my caravan ready for the winter. Very informative regarding the fuel hose and delivery system, since I have only once since installation a week ago had a successful run of the heater. Suffice to say, mine came with the poor vinyl large bore fuel line, which I see now I need to replace from the pump. (luckily I have plenty of the 4mm hard bore hose in my workshop). Another issue is that in the caravan, I am very limited in installation location of heater and fuel tank, such that without putting the pump outside / under the van on the chassis, it's near impossible to get a steady incline up to the feed point of the heater. What happens currently is the heater will not properly ignite, makes a very impressive smoke generator with clouds of white diesel vapour!! It's good to see from your video now how I can hopefully resolve my problems just changing the feedline!
Thanks for the great info in your videos. ;)

Pleased you found the videos helpful Martin. JMcK
Thanks for your detailed advice!
Was having issues with the heater on our used van and found they had used 4-5mm automotive fuel hose.
Cheers mate 🤙
Hi Tim,
Good quality automotive hose is fine for the suction side of the pump, but on the delivery side of the pump to heater you should use narrow bore hard nylon fuel hose. JMcK
You are awesome at explaining this stuff. Thank you so much, can't wait to try some of these improvements to my setup!
Hi LM, thanks for your positive comments. Pleased the videos were of some help. JMcK
