everytime i go to add a new mod to my boat i google how to do it and everytime the green machine has already got a vid waiting for me :) pretty cool love ur work
One can build a bracket to mount to the rear of the transom corner brace, with enough setback depth to keep the body of the filter out of harms way ( but serviceable), and avoiding messing with your hull side. Awesome information! Stay safe.
So agree with what you say about getting a feel for bolt torque being vital, luckily I got it fairly quickly as a kid and never really thought about it but it was about twenty years before someone pointed out to me that the force you exert is about the same no matter what size the bolt because the spanner lengths are designed to match the size and give you the right leverage to apply the appropriate torque for general use if you have "average" strength.
Absolutely correct. Unfortunately with plastic fitting and tapered fittings I’ve found it more difficult to judge the correct torque, especially when using a sealant which also reduces friction while torquing things down. Fortunately most good quality fittings are generally forgiving, especially when new.
Ha! We just went to take our first boat away for its maiden run and smelled a fuel leak. Mongrel to get at, wasn't sure about thread sealant or bleeding air out of the system, but of course Dangar Stu has me covered! I think every question I've had you've had a video on ... Thanks! Great channel. Cheers PP
Great video Stu. Where I am located in NJ USA ethanol is in all our fuel at 10%. One of these filters is a must as ethanol attracts water like a magnet. My big boat with the Yamaha 150 has one installed, I will be adding one to my small boat with the evinrude 48 next season. Thanks for the video!
i love the details you put in your videos Man , very intelligent and smart working skills you have :) watching your video i can carry all the services on my outboard , before i used to pay $700 for a service lol thanks alot for sharing these videos:)
Great job on this - really key to have this on a boat, surprised it didn't already have one. I think I would have put in on the inside of the brace, facing towards the stern. The space under the brace is wasted space and it would have been out of the way. Kind of a pain to install this way, but you only have to do that once.
Again, always the best videos on boat work. Would love to have a cup of coffee with you someday but a couple of thousand miles difference make that hard. Thank you for the best videos on youTube
Another video that was very informative and easy.looks like the only hard part finding a place to put it. thanks for your time and effort. peace from Canada.
Hi mate. Yeah, it can be tricky on some boats. If you really can't find anywhere you might be best to make up an aluminium bracket for it and rivet that on somewhere.
A good clear video once again, well done Dan. For me though, if I had two engines and two tanks, I would have two fuel filters! But tat is just my aircraft/navy training of keeping things separate, and if I could afford two engines, I could afford two filters :-) . As the fuel system up to the engine is not pressurised I don't think there is much chance of a fuel leak at higher flow rates, may be air leaks, but not fuel. Priming the system and then letting it sit for a few days to see if a leak occurs is good idea though.
Hey Ron, very good point about having things completely separate. If you get water in one fuel tank, you don't want to take out both motors! You are right about leaks too. Really you are causing a bit of a vacuum so sucking in air at high revs is more likely, although not quite as dangerous as leaking fuel everywhere. ;) I've certainly seen problems with boats though where it would run well at low speed then struggle at high speed and it turned out to be a split in the fuel hose sucking air with no signs of a leak.
Lesson learnt, it happened to me the Tank cap with fuel gauge broken and I left outside 3 weeks thought everything is okay when I tested but when on the lake the engine bogged down due to rain water in the tank, luckily I had two tanks and switched and start the engine took long time to start but after it's started the new fresh gas ran okay.
I've mounted & installed several of these, be sure to mount it more out of the way, like to one side or out of sight even. They do not capture very much water if you are ethanol free, but a must do for any and all outboards or any engine for that matter.
Gday mate i put one of these in my last boat but had it after the bulb fixed to the back of the rear seat i dont know if it makes any difference at all but i didnt have any problems ,used to drain the clear sight bowl at the end of winter ready for the summer season good piece of kit i think dont want no nasties getting through even though thier is a filter on the side of the engine anyway good video.
I think it's pretty 50/50 where you put the primer bulb. The idea with having it afterwards is that you can supply direct pressure to the outboard, but once the bowl is full its going to have the same effect, and it does make it easier to fill the bowl from empty.
Thanks for this series of vids on the Green Machine. I'm new to boating and it's nice seeing each component of a boat laid out in a vid. Best of luck on the project mate!
What are you supposed to do with the fuel tank vents? When should they be opened? When should they be closed? Is it different if they are portable tanks vs built in tanks? Seems like always open is the thing to do with portable so they don't collapse when running and don't swell in the sun. Built ins aren't in the sun so close when not in use?
For those who follow and are doing fuel line upgrades , I too have found disappointment in the oem standards regards to the fuel side of engines. Here we have a boating industry that I have seen use clamps and hoses on sub floor tanks that have no flaring for clamps to work under pressure and hoses just slide off over time or clamps that rust away. Some may find some fuel primer devices some what restrictive if they need gravity fed or very low vacuum requirements. Best to test bench these primers before having issues on the water. The hard plastic tanks need upgrading to have high point blow off valves installed for pressure discharge and better low point fuel pick up design to the tanks so no air gets sucked in when your trying to avoid hitting rocks in odd rough whether, you don't need a stalled engine at this point when your on your last tank 1/4. In filters fuel should travel to the base water trap first leaving water behind before traveling up through the filter element. Hope this paragraph/comment saves some lives.
Is there a difference between having the primer bulb connected to the input side of the filter? The Eastener which I have just purchased has a replacement cardboard “corrugated” filter. What’s the difference between that and the metal one which you have please?
Question i have a leaking fuel/water separator at the fitting and hose meeting point. Would that cause air into line and not allow my motor to crank over?
Thanks for this video, I have a question: I didn't notice you bleed the filter where did all the air go? There must have 1/2 litre of air in the filter. If it's because the engine has carbys and the primer goes hard once air has passed and fuel has filled the bowls to operating level I can understand. I have a 2022 Yamaha 60 which I think would have injectors, I would think the system would need bleeding at the filter once installed. Please share your understanding on the matter
Question is, could you have 2 fuel tanks connected to the filter and so it draws fuel from either tanks to 1 outboard ? So 2 in to the filter and 1 out to the outboard?
Hello Mr. Dangar I'm currently restoring a pontoon boat which has a 115 HP Johnson 2 stroke and I'm planning on installing a water separator just like yours. My question is "will my motor being a 2 stroke work properly with a water separator since its oil and gas mixed? "
Hi John, installing a water separator like this with a 2 stroke is no problem at all, it won't affect the oil and will definitely help protect you from water.
You refuse to call it un boxing, Funny. Anyway, I read all posts first, looking for an answer so i wouldn't be one of those that ask a question that's already been answered. Just got a boat, has water-separator, solid, no bowl, or drain, but they have it installed seemingly upside down. Filter on top, inlet and outlet lines on bottom. I can find lots of info about them, but nothing about if the solid ones can be upside down. or not.
Hi mate, no, they definitely need to be installed with the bowl hanging down. Water and debris are both heavier than fuel and need gravity to trap them in the filter.
Are there instances where mounting a fuel water separator too high can result in loss of prime with air in the system? I changed over from a sierra 18-7945 to the yamaha filter. The yamaha filter was twice as deep! Now I am having trouble with the primer ball getting empty of fuel and the motor starving itself. Any advice is appreciated, thank you.
Yes, and it has been so much better than that grey hose you often see. It is on the water and out in the Australian sun every day and is still perfect.
Does it matter where you have the Primer Bulb? Mine is between Tote Tank & Filter then from Filter is straight hose to Outboard. Shall i put Bulb in between Filter & Outboard like you have yours? Or is it okay how it is. Cheers
Hey Will. I definitely think these filters are essential too. As for the location I think there are pros and cons to both possible position. You are right in that it can be harder to prime with it after, but one it is done I prefer to have it closer to the outboard itself.
Do the plugs have to be added? And if they are not what are the effects? I bought a boat and I've noticed the plugs are not added and I've been having the hardest time figuring why every primer bulb I use loses prime
How often do these need to be replaced? What about the ones withOUT the clear bowl at the bottom--replacement time? Thanks for all the great videos you've made! I'm a boat newbie and they are really helpful!
Maybe I got a bad brand, but I had one just like that on my old boat and it was hell every year getting that plastic bowl to separate from the filter. Even if I used a vice the inner portion of the filter would spin with the bowl and the gasketed surface wouldn't let go. I would have to hammer a screw driver through the filter, then put it into the vice, then use a pipe wrench on the bowl.
Hi. a few months ago, I added this exact water separating filter to my boat. Previously, I just had a spin on fuel filter. Yesterday, I decided to drain the bowl and I drained a lot of gas into a Jar. My assumption is that the bowl is full of gas, and since water is heavier, it collects at the bottom - thus I only need to drain a small amount from the bowl? Is that a correct assumption? Or is something wrong with my filter? I was expecting to only drain a little water out. I was surprised when I got a large Jar of gas. Many thanks!
If you don't have any water in your fuel, the bowl will contain nothing but pure petrol. The idea is that you will be able to see a thin layer of water in the bottom of the clear bowl if it is there and you just need to drain that off until the bowl is clear again.
Is there any reason for mounting the filter between the bulb and tank, and not between the bulb and engine. The way its set up now, the bulb has to suck the fuel through the filter - instead of pushing it through the filter. Ive done it like you have, and its really hard for the bulb to suck the fuel through... It will, eventually, do it, but if you could "push it through" it would go so much faster... Or am I missing something?
Thanks for the video. Trying to knock out various bits of service on the used boat I bought last summer while it's still winter and this is one of them. My kit is missing the barbed connectors and hose clamps so I'm going to have to run back to the shop tomorrow. Since my boat hasn't had a water separator in it for who knows how long should I expect the filter to foul quickly?
Hey Dangar. I have a question to which the answer is not so easy to find on the internet. I'll keep it short: 2 stroke, no autolube so mixed fuel. 10 micron filter? Yes or no. I don't know what happens to the oil in the fuel while going through the filter.
How do I know if the gear change on the base is wrong on Mercury 150 Hp optimax, because there is only forward, no way to adjust on cable. no reverse. How to adjust the exact position on base, before putting it back
What's that bracket made of, metal, or some sort of plastic? Is it because of ethanol in fuel these days (at least here in the US), and separation can easily happen? Or do you have some other issues with fuel and water for boating? RichE
The bracket on this one was aluminium. Good question about the water in fuel, I think there are a few reasons. One is that the fuel tanks are underground near a water way as we buy it from marinas. Another is that the marinas don't have the turn over that a busy petrol station will have so the fuel is older. Outboard tanks have breathers that are exposed to the rain and the bilges often have water in them where the fuel lines run. I think it is a combination of all these things that makes boats particularly bad.
With the “two in, two out” bracket, can you run one single fuel water separator for twin engines? In other words, for the sake of saving space, could I get away with mounting one “two in, two out” filter for my twin Yamaha F100’s? I have single 90 gallon fuel tank, with two independent fuel lines to each engine. Also, will one 90gph, 10 micron filter suffice for my application? Dangar Marine has the best content for engine repairs/maintenance. Best regards from Sunny San Diego, California!
I am a huge fan of your videos! They have helped me so much as a new boat owner. My question is if you have the simpler filter with no clear bowl on the bottom, can you unscrew it and dump it all out? Or should it just be replaced when you remove water? Thanks!
You can, you just need to be a bit careful about where you get each. I'd put the Duralac on the hull and under the head then put a bit of thread locker on the shaft once you had it pushed through.
You need to make sure the air can escape while priming, so sometimes for the initial priming I will take the end of the fuel line that connects to the outboard until the priming is finished. Either than for use a screwdriver to push the ball bearing in that closes the valve. Filling the filter with fuel first obviously helps too.
Going to install an electric bildge into the boat but it has strats to have strenght so I don't know if I can do all sections with one bildge or just one section with one bildge.
It is a trailer boat? If so you could try filling the bilge with a hose and see where the water flows. It is quite common for a boat to need multiple bilge pumps for different sections but sometimes people just drill transfer holes through the beams to allow water to travel from one side to the other.
It isn't really a problem to share a filter. Having a second of everything (tank, filter line etc) for the kicker is best but there is a limit to how much redundancy is practical.
Hey, Commenting quite late on this video but we would need your assistance. We have mounted it the same way you have, but we don’t manage to get the pump to run fuel from the tank through the filter and out on the other end. Currently we don’t have an engine so we do this process manually with the hand pump. We have filled up the filter with fuel now and still get and good result. Do you have any tips and tricks? What we might have done wrong.
There is a ball valve in the end of most outboard fuel hoses that shuts off the fuel until the line is connected. You can press it in with a screwdriver or something to open it manual.
@@DangarMarine thanks for the swift reply. We currently don’t have this attached so the hand pump is free and open. Maybe this is causing the issue? That no pressure is built up. We moved the hand pump and connected it directly to the tank and was able to get fuel, removed the hand pump and connected the hose to the fuel filter. After then moving the hand pump to the other hose (outgoing from the filter) we still get no fuel.
Thanks Stu. Please comment on Merc I/O fuel-water separator filters that don't have the clear bottom and drain valve. They look like an oil filter. Do you have to dump them out periodically to remove the water? I just replace them seasonally. Good enough?
Hey Bruce. Just replacing them seasonally is fine. The only exception would be if you got a load of water in the fuel tank from being left open in the rain or something.
I have a 90 horse 2 stroke that I premix gas. would a filter like this flow the mix or would it separate the fuel/oil mix? having a problem with water getting in my fuel now.
Question, Do you have to fill the water separator with Fuel prior to installation? My filter recommends it to keep air from the fuel lines. However, it's in a tight spot and I have to put in the filter at an angle so I wanted to avoid pre-filling if possible. I figured the air would be replaced with fuel any way. Any thoughts?
Thanks for responding. I tried priming with it empty but after about 150 squeezes, I wasn't getting anywhere... too much air in the filter is my guess. So instead of taking it out since it was difficult to install on my tightly packed bass tracker, I took a small one gallon gas tank and my previous fuel line with a primer bulb and attached it to the intake of the fuel water separator, other side in the gas of course. I primed a few times and it was enough to fill the fuel water separator filter. I then disconnected the one gallon tank from the intake and connected the real tank and she's now purring like a kitten. I appreciate all your videos! The one you made about cleaning the steering cable saved me from having to replace mine. Thanks again! The marine shop would have charged all kinds of money for both these jobs. Thanks to your videos, I'll be out fishing soon. :)
I think everyone that's spun a spanner has done the old "oh s$h1t!, i think I've done that up a bit too tight...., yep, I've split it!" I double hose clamp every fuel hose if possible; thought I read somewhere that double clamping was the "industry standard" In fact, just recently noticed that the triple clamped fill hose on a boat was ever so slightly leaking......... ok they were a tad loose but I'll pull the hose off and use a bit of stag paste before summer. My first boat came with a spin on water separating filter that didn't have a clear bowl. When I changed it, (to one with a clear bowl) it was 99% full of water!
Dangar Marine has been my goto for everything boating. I’m a ‘newie’ to boating and these vids have been brilliant.
everytime i go to add a new mod to my boat i google how to do it and everytime the green machine has already got a vid waiting for me :) pretty cool love ur work
I'm pretty laid back but the Green Machine has plans for world domination. ;)
hahahahah
Your videos are second to none. I'm a mechanical and electrical power engineer, now enjoying retirement fixing boats 🚢😎
Refuse to call it an "unboxing"..... Now i love your videos even more.... keep up the good work and info. Thanks. Happy new year.
Happy new year!
Great video Dangar.
I’m installing a Sierra filter for my 1995 Johnson 130hp. I was shocked to learn my boat never had one.
YOUR VIDEOS ARE VERY INSTRUCTIVE AND YOUR EXPLANATIONS ARE VERY GOOD. I HAVE LEARNED A LOT FOR YOUR TIME IN MAKING THESE VIDEOS, THANKS MATE
You're welcome mate. :)
One can build a bracket to mount to the rear of the transom corner brace, with enough setback depth to keep the body of the filter out of harms way ( but serviceable), and avoiding messing with your hull side. Awesome information! Stay safe.
Thanks to your videos my outboard is running a lot better now
Glad to hear that. :)
Great video, will be installing one soon on my new first boat, had no idea about the importance of these filters. Cheers
Great video, best I've seen on replacement 😀
Excellent video. As a newbie these videos are great. Getting my first boat this weekend and these videos are a great help.
Thanks mate. Congratulations on your new boat. Enjoy! :)

Yep, there is a reason all those spanners are different sizes, you are dead right. :)
Absolutely correct. Unfortunately with plastic fitting and tapered fittings I’ve found it more difficult to judge the correct torque, especially when using a sealant which also reduces friction while torquing things down. Fortunately most good quality fittings are generally forgiving, especially when new.

Yeah, ethanol really is an issue in boats and for sure these filters are a must. Always good to have a winter project. :)
The most valuable accessory to any petrol or diesel engine. It will save the pump carb or injection system!
Thanks for the video! Really appreciate your practical approach to marine repair & projects w/out all the fluff -
Thanks Jack, glad you liked it. :)
It's a great way to get water out of a built in fuel tank as well. Great vid.
i love the details you put in your videos Man , very intelligent and smart working skills you have :)
watching your video i can carry all the services on my outboard , before i used to pay $700 for a service lol
thanks alot for sharing these videos:)

Nice one, just ordered this after getting my engine back coz it had shit in the carb gonna fit it myself now I know what to do cheers ;)
These filters are a real life saver, I reckon there should be one in every boat. :)
great instructional video, thanks for posting
You're welcome. :)
Nice and clear instructions. thanx
I love the way you say aluminum took me awhile to realize what you were talking about lol.

Excellent video on how to install a fuel water separator kit. Thanks.
Thanks Tom!
great instruction-thank you
Glad it was helpful!
Got the same filter on my boat.
"Clockwise as always" while screwing on Anti-Clockwise. ;-)
It's all a matter of perspective. ;)
I always use the term "Lefty Loosen" to undo things, so it's right to tighten.
Is there a difference between having the primer bulb connected to the input side of the filter? The Eastener which I have just purchased has a replacement cardboard “corrugated” filter. What’s the difference between that and the metal one which you have please?

Question is, could you have 2 fuel tanks connected to the filter and so it draws fuel from either tanks to 1 outboard ? So 2 in to the filter and 1 out to the outboard?
Great Videos. Do tou think is a must to have a Fuel water separator in 4 stroke fuel injected outboards?
wow just did this last week. Wish I could have seen this video!
How did it go?
+Dangar Marine it was frustrating at first but eventually I got it and it ran smoothly
Can you use these on a 2 stroke outboard as well
Hello Mr. Dangar

Hi Dan, good video. What's the trick in putting on the fuel line onto the nipple that screws into the housing. Thanks Kieran
Did you use automobile grade hose on the fuel bulb?
Yes, and it has been so much better than that grey hose you often see. It is on the water and out in the Australian sun every day and is still perfect.
Does it matter where you have the Primer Bulb? Mine is between Tote Tank & Filter then from Filter is straight hose to Outboard. Shall i put Bulb in between Filter & Outboard like you have yours? Or is it okay how it is. Cheers
My filter is called QS 802893Q01 STD, it does not have a plastic bottom. Does it fill the same role?
Is it just to screw it off and empty it?
You should write a book,
Thanks.
I prefer to have the primer bulb before the filter to make initial filling of the filter easy. All boats should in my opinion have a water separator.
Hey Will. I definitely think these filters are essential too. As for the location I think there are pros and cons to both possible position. You are right in that it can be harder to prime with it after, but one it is done I prefer to have it closer to the outboard itself.

Is this good for a 20hp fuel injection outboard?
Can this type be used for a 30hp?
Does it matter what side the priming bulb goes on????
what kind of connector do you need to run another line to a kicker motor from the same water separating filter?
Is it ok to use fuel resistant gasket dressing & sealant on the threads of the blanking plugs & barbs?
Anything fuel resistant and non-migrating should be fine.
Dangar Marine awsome, thanks mate. love your videos.
Thanks for the vid. You leave the original filter under the cowling in place when using these as an additional filter right?
That is correct
Maybe I got a bad brand, but I had one just like that on my old boat and it was hell every year getting that plastic bowl to separate from the filter. Even if I used a vice the inner portion of the filter would spin with the bowl and the gasketed surface wouldn't let go. I would have to hammer a screw driver through the filter, then put it into the vice, then use a pipe wrench on the bowl.
It can help a lot if you put a smear of rubber grease around it before assembling it.
Hi. a few months ago, I added this exact water separating filter to my boat. Previously, I just had a spin on fuel filter. Yesterday, I decided to drain the bowl and I drained a lot of gas into a Jar. My assumption is that the bowl is full of gas, and since water is heavier, it collects at the bottom - thus I only need to drain a small amount from the bowl? Is that a correct assumption? Or is something wrong with my filter? I was expecting to only drain a little water out. I was surprised when I got a large Jar of gas. Many thanks!
If you don't have any water in your fuel, the bowl will contain nothing but pure petrol. The idea is that you will be able to see a thin layer of water in the bottom of the clear bowl if it is there and you just need to drain that off until the bowl is clear again.
Many thanks!!! :-)
Is there any reason for mounting the filter between the bulb and tank, and not between the bulb and engine. The way its set up now, the bulb has to suck the fuel through the filter - instead of pushing it through the filter. Ive done it like you have, and its really hard for the bulb to suck the fuel through... It will, eventually, do it, but if you could "push it through" it would go so much faster... Or am I missing something?
It is mostly about pushing fuel directly into the carburettor bowls once the system has been primed the first time.
Awesome as usual. Cheers. G
Thanks for the video. Trying to knock out various bits of service on the used boat I bought last summer while it's still winter and this is one of them. My kit is missing the barbed connectors and hose clamps so I'm going to have to run back to the shop tomorrow. Since my boat hasn't had a water separator in it for who knows how long should I expect the filter to foul quickly?
You made a nice video
Hey Dangar. I have a question to which the answer is not so easy to find on the internet. I'll keep it short:
2 stroke, no autolube so mixed fuel. 10 micron filter? Yes or no. I don't know what happens to the oil in the fuel while going through the filter.
It is a good idea, it won't filter the oil out from the fuel.
@@DangarMarine my man. Thanks for the quick response 👌🏻
Very usefull..thanks
Welcome 😊
How do I know if the gear change on the base is wrong on Mercury 150 Hp optimax, because there is only forward, no way to adjust on cable. no reverse. How to adjust the exact position on base, before putting it back
Have you heard about Mallory filters? I cannot find a unit like I saw in a Mallory video. Thanks for all your work.
Can't say I have ever heard of Mallory, sorry.
Good job
Thank you
What's that bracket made of, metal, or some sort of plastic? Is it because of ethanol in fuel these days (at least here in the US), and separation can easily happen? Or do you have some other issues with fuel and water for boating?
RichE
The bracket on this one was aluminium. Good question about the water in fuel, I think there are a few reasons. One is that the fuel tanks are underground near a water way as we buy it from marinas. Another is that the marinas don't have the turn over that a busy petrol station will have so the fuel is older. Outboard tanks have breathers that are exposed to the rain and the bilges often have water in them where the fuel lines run. I think it is a combination of all these things that makes boats particularly bad.
What sort of maintenance is required for the fuel/water separator? How often should I check it and replace it?
I would replace them about every year, but check the clear bowl at the bottom for water just about every time I go out.
Thanks
With the “two in, two out” bracket, can you run one single fuel water separator for twin engines? In other words, for the sake of saving space, could I get away with mounting one “two in, two out” filter for my twin Yamaha F100’s? I have single 90 gallon fuel tank, with two independent fuel lines to each engine. Also, will one 90gph, 10 micron filter suffice for my application? Dangar Marine has the best content for engine repairs/maintenance. Best regards from Sunny San Diego, California!
I am a huge fan of your videos! They have helped me so much as a new boat owner. My question is if you have the simpler filter with no clear bowl on the bottom, can you unscrew it and dump it all out? Or should it just be replaced when you remove water? Thanks!
You can tip it out periodically. I would do it into a clear jar so you can see if there is any water in it.
If you use stainless steel bolt in an aluminium beam (e.g. a mast) that is tapped, can you use Duralac and thread locker at the same time?
You can, you just need to be a bit careful about where you get each. I'd put the Duralac on the hull and under the head then put a bit of thread locker on the shaft once you had it pushed through.
i have a kit like that but there is no drain the bottom of the filter is solid..like a regular oil filter can I still use this style?,
Yes, I believe so. You can order open bottomed filters that have the same thread I believe and then you will just need to get the matching drain bowl.
its a size restraint issue cant use the filter with the drain,,how often should I change the filter? hours? weeks? thank you
Can you put the primer bulb before the filter
Yes, you can.
Very good but I have trouble getting it primed!
You need to make sure the air can escape while priming, so sometimes for the initial priming I will take the end of the fuel line that connects to the outboard until the priming is finished. Either than for use a screwdriver to push the ball bearing in that closes the valve. Filling the filter with fuel first obviously helps too.
@@DangarMarine 👍🏼
Question if the primer bulb is between the tank and the water separator is it incorrect?
.
That's fine, you can have it in either position.
Going to install an electric bildge into the boat but it has strats to have strenght so I don't know if I can do all sections with one bildge or just one section with one bildge.
It is a trailer boat? If so you could try filling the bilge with a hose and see where the water flows. It is quite common for a boat to need multiple bilge pumps for different sections but sometimes people just drill transfer holes through the beams to allow water to travel from one side to the other.
+Dangar Marine Ok I will have a go doing that.
Would it be wise to run a kicker and the main off this type of filter and a single tank?
It isn't really a problem to share a filter. Having a second of everything (tank, filter line etc) for the kicker is best but there is a limit to how much redundancy is practical.
Hey,
Commenting quite late on this video but we would need your assistance.
We have mounted it the same way you have, but we don’t manage to get the pump to run fuel from the tank through the filter and out on the other end. Currently we don’t have an engine so we do this process manually with the hand pump. We have filled up the filter with fuel now and still get and good result.
Do you have any tips and tricks? What we might have done wrong.
There is a ball valve in the end of most outboard fuel hoses that shuts off the fuel until the line is connected. You can press it in with a screwdriver or something to open it manual.
@@DangarMarine thanks for the swift reply.
We currently don’t have this attached so the hand pump is free and open. Maybe this is causing the issue? That no pressure is built up. We moved the hand pump and connected it directly to the tank and was able to get fuel, removed the hand pump and connected the hose to the fuel filter. After then moving the hand pump to the other hose (outgoing from the filter) we still get no fuel.
Thanks Stu. Please comment on Merc I/O fuel-water separator filters that don't have the clear bottom and drain valve. They look like an oil filter. Do you have to dump them out periodically to remove the water? I just replace them seasonally. Good enough?
Hey Bruce. Just replacing them seasonally is fine. The only exception would be if you got a load of water in the fuel tank from being left open in the rain or something.
I have a 90 horse 2 stroke that I premix gas. would a filter like this flow the mix or would it separate the fuel/oil mix? having a problem with water getting in my fuel now.
No, this type of filter works just fine with premixed two stroke motors.
Dangar Marine thank you sir. your videos have helped a ton on my last few projects
Question, Do you have to fill the water separator with Fuel prior to installation? My filter recommends it to keep air from the fuel lines. However, it's in a tight spot and I have to put in the filter at an angle so I wanted to avoid pre-filling if possible. I figured the air would be replaced with fuel any way. Any thoughts?
It's easier to fill it first, but not required, it will just take more priming if it is empty.
Thanks for responding. I tried priming with it empty but after about 150 squeezes, I wasn't getting anywhere... too much air in the filter is my guess. So instead of taking it out since it was difficult to install on my tightly packed bass tracker, I took a small one gallon gas tank and my previous fuel line with a primer bulb and attached it to the intake of the fuel water separator, other side in the gas of course. I primed a few times and it was enough to fill the fuel water separator filter. I then disconnected the one gallon tank from the intake and connected the real tank and she's now purring like a kitten. I appreciate all your videos! The one you made about cleaning the steering cable saved me from having to replace mine. Thanks again! The marine shop would have charged all kinds of money for both these jobs. Thanks to your videos, I'll be out fishing soon. :)
Where do you find the parts? Is it just a fuel water separator for a diesel engine?
I think everyone that's spun a spanner has done the old "oh s$h1t!, i think I've done that up a bit too tight...., yep, I've split it!"
I double hose clamp every fuel hose if possible; thought I read somewhere that double clamping was the "industry standard" In fact, just recently noticed that the triple clamped fill hose on a boat was ever so slightly leaking......... ok they were a tad loose but I'll pull the hose off and use a bit of stag paste before summer.
My first boat came with a spin on water separating filter that didn't have a clear bowl. When I changed it, (to one with a clear bowl) it was 99% full of water!
Yes, if the barb is long enough, double clamping is a good way to go. It's amazing how much water the filters can trap, well worth having!
