Part 38: Fuel Tank Restoration With POR-15 Sealing Kit - My 76 Mazda RX-5 Cosmo Restoration

- I guarantee that aside from part 38 of my '76 Cosmo Restoration, you will not find more footage on TH-cam of someone shaking a fuel tank. You have my word that this is the most tank shaking coverage you will see in any video. Why so much tank agitation? Because in this episode I clean and seal the 40 year old fuel tank using the POR-15 fuel tank restoration kit. This is something which several have requested be shown so I figured as sealing was a common issue for old fuel tanks, why not dedicate an episode to the task. I begin by recycling some of the cleaning footage from the past two episodes then move right into the process of the POR-15 kit. First any remaining debris is "chained out" by using the old trick of rattling some chains around inside the tank. Then the tank is cleaned with the supplied cleaner, etched with MetalPrep and finally coated with the sealer. The end result is a tank looking better inside than the day it came the assembly line which will not be subject to future corrosion. To go with the spiffy clean interior, the outside is given a coat of POR-15 rust preventative paint as well.
And did I mention this is my first episode in HD?! - ยานยนต์และพาหนะ
Excellent detailed information about an obnoxious task. Don't know if this will help anyone but when it came time to blow my tank out to avoid flash rust, I jammed my leaf blower in one of the big holes and let it blast away. It moves a lot of air much faster than my air compressor does. Thanks for posting vids like this. They help keep me going on a long project when you see others whittling away one mini-project at a time!
Thank you! The leaf blower idea is a good one. Probably a lot more energy efficient than using the compressor as well.
I also use the blower to dry off my Harley after washing to eliminate spotting and allow me to go right to polish or waxing.
Well done. thanks for the gas tank sealing video.
Thank you so much for the upload and in HD at that! Your project is truly inspirational!
I was gonna say it'd be funny if this resto-mod job ended up being 76 parts, but I see you've already touched on that.
Fuel system work looks like SO much fun. Glad to see it's working out for you.
Also like the new Camera setup. Picture quality is great!
Keep up the great work!
chapsy1983 I'm actually thinking it could be less than 70 parts because finally, I can see the end coming. The list of large mechanical and fab projects is very short at this point and I can see moving to the interior closer and closer. I've learned over the years that the fuel system is one of those things which will make or break a project car. At the least it can cause constant tuning problems and unpredictability, at the worst, blown engines or burned down cars.
Very good point, it is a critical area, and I can understand why you were so particular about refurbing it just right.
really glad to hear this project is starting to come around for you. I'm still anxiously awaiting the finished product!
Keep it up man!
The HD has really brought it up a notch! Now I can watch these on my lounge TV. The new camera got a good workout with the quick rinse!
Also, worth the wait for HD flowing locks
Hi Aaron, I am just starting a restoration on my car and I have a lot of sheet metal work to and I am just loving your videos on Metal work cause you are giving me a lot of ideas on how to perform these repair. Keep up the good work and keep the videos coming. Thanks.
I really liked the fight with the water hose. Great informational video, I feel more prepared to restore the tank in my Datsun now.
That’s an amazing result, no doubt due to your extraordinary prep work.
Ya, he's very good with that scrub brush sction...
Jokes aside, great explanations for the long way to do it!
I've a small motor tank that rusted until seeping around the petcock. I plan to use muriatic acid then baking soda, then Denatured alcohol to dry. I think that should be enough if the water and baking soda get the rust out. If not, a small chain.
HD! Awesome! The best thing is the improvement in sound quality (y)
Good job, looking forward to the next video. Like how precise you are in your work.
that tank is now beautiful! well done as always! "she said" was a good one. ;)
Awesome job ! Love watching the vids , keep it up!
Hahaha I've been binge watching ur videos at work, your puns are funny but nothing made me crack up more than your face in the out of control hose scene. And we all know how much you love them "hose" xD great videos Aaron.
Man...what a process. Looks like I will be doing the same sometime soon. Great Vid...thanks for the laughs !
Hello, are admired by your ability to address and resolve the various stages of radical work that you are facing, are anxious to see the developments of your restoration. I am a fan of mechanics and I have some experience of motors, also I have a good manual and I would make you my compliments.
An excellent job, as always, waiting for the next video
Good thorough job on the old tank, there.
The audio is significantly better. Thanks for that.
Great video. My 72 240z was put away in a garage 30 years ago with fuel in it. The fuel turned to tar and now I’m in the same boat.
Probably one of the better videos I have seen !!
Awesome job , and very good video 💪🏼💪🏼
I had a VW tank that had a bunch of rust in it. I tried everything I could think of. I finally bought 15 gallons of vinegar and let it set for about a week. Best trick I found.
Just did that for a VW Thing, the tank looked "OK" but after letting it soak in vinegar, wow what a difference. I didn't think there would be that much rust and crud, the vinegar looks orange with A LOT of what looks like sludge/mud. So it must have been pretty bad. I got this 2 years ago, and I saw the last service within that year the tank was drained of gas and "cleaned" what ever that meant. I think the dealer ripped off the previous owner on alleged services they did to the Thing, because I had to replace hoses and gaskets that should have been replaced when they took care of the tank. Today I drained/rinsed the vinegar and did a phosphoric etch, tomorrow I will use POR gas tank sealant, that's some good stuff!
Did you use the entire amount at once?
Watchin' you struggle and hate everything, shaking that tank around is some funny shit man.
nice job. I like the strange quarters you work in
4 years since but, Cool and instructive...well done mate ;-)
hey Aaron, sweet videos. I am also a fabricator/ perfectionist. I have been glued to your videos because you do a very good job showing the processes involved. so many car shows on TV make everything look so quick and simple. something as simple as a fuel filter mount takes hours to complete... well done.
+04snopro Thank you! And yes, I hear you about the car shows. Having been involved in production of one, it was always amusing how the camera crew would so up for an hour every few days to film the installation of parts that took 2 days to fabricate, fit or troubleshoot. I try to show what really happens, while still cutting out the boring or repetitive stuff. Each one of these episodes is the result of about 8 - 12 hours of footage.
I watched this guy for long time and I have to admit that he is hilarious :P
Great job with the car i have to watch all :P !
Good job. Thank you for sharing.
Aaron......if you cut your siphon hose at a 45Deg angle(5 in. from the discharge end) about halfway thru with the point to the bulk tank.....then push shop air thru the cut toward the discharge end of the hose. the shop air will pull a very nice vacuum and start the syphon without your mouth getting any nasty stuff! I have been doing this for years. it only takes a few seconds of shop air and presto.......syphon is started.
john pelsor Brilliant! That would be the venuri effect in action!
Looking forward to next part ;-)
Got my velocette venom tank to treat with a POR 15 kit glad I watched this first Brilliant.
And I'm glad to have helped!
Great video Aaron loved it
Good job!!! Well done!!!
Amazing job!
Wow amazing work. I have the exact problem with my 1991 Miata gas tank. The fuel pump and the whole assembly unit also has that white & yellowish crud on it. I also see some inside the tank with rust and other gas related sludge. But unlike your gas tank I don't have that grease sludge that was one gasoline. There are so many Miatas in the junkyards here in southern California that I'd rather hunt for a good gas tank. Great video. You are one very dedicated dude to your classics. Hopefully I won't have to do that to my 79 Caballero/El Camino. It runs great so I doubt it.
Yes, I think if you have the option to get a new tank, then go with that option. It might not be cheaper, but it will certainly be a lot less work than restoring the existing tank.
Thanks for this video. You have given me hope for my 78 280z tank which i cant find a plastic reproduction. Based off this video.
No problem. As long as the tank isn't rotted through, the POR15 sealing kit should do the job. Even pinholes will seal up, but large areas will need to be CAREFULLY welded.
Garth Algar rebuilds an old Mazda...loving the vids dude,looking forward to seeing the next instalment.
Great video, I learned a lot and did my first gas tank in May (1967 M151A1 ex US Army MUTT) y tank didn't come out as perfect as yours, but I have a VW Thing that will get the POR-15 treatment tomorrow. I used vinegar to get rid of the rust, followed by a phosphoric acid etch. I saw some very minor flash rust, but I think it might be OK, I might do another phoshoric treatment. I used a back pack leaf blower and heat gun dried out very quickly. Keep up the great job, I know it takes a lot of effort to make these videos while working on a project by yourself, and could be done in half the time if it wasn't for recording and editing. I like your instructional approach and humor!
The flash rust is OK if using the POR-15 sealer. It's sort of expected. Just make sure that all of the white dust is blown off or there will be adhesion problems.
Good job, greetings from France ;)
Gave a thumbs up just for the over the top effort
Barrel laughing at 2;36 for the spot on Jacob's Ladder effects. Great stuff there. And I think my heart dropped when the hose got your camera. Looks like its Ok though. Great video. Thanks.
riverseine Thankfully the camera was fine. Just water on the lens.
awesome job!
i really thought this man was clownin the glam band spandex rocker in the 80s peeps. until i saw him the second time.!!!! this guy rocks!! i lost my chain to!
awesome video!
The Ryan Smyth/Kim Mitchell of restoration. Your videos are awesome Aaron. Attention to detail is top-notch. Your LED video blew my mind and I'd love to attempt a similar project with my car.
Cheers!
Nice to hear that. Are you going to put up some pictures/videos of your LED lights?
I might eventually once the build gets sorted (84 Rabbit GTI)
Cheers!
great video!
Well done Aaron. I cant believe the car started with all that nasty goo inside.
You can also detail your trunk space and spray it with old school speckled trunk paint (since you got the tank looking great).
That tank came out really nice. Text book, really.
I'm actually amazed with how well it cleaned up inside considering with what I started.
aaroncake Yeah, it looked horrible inside.
Yay we have 720p!!
I really like your work man! Keep it up!
Andres Barquero 720P for now. I may move to 1080 in the future but even on my quad core i7, editing it lags. Mainly due to my ridiculously old version of Adobe Premiere but ALL NEW PREMIERE VERSIONS SUCK.
Don't get me wrong I really appreciate that you upload 720p content: that way I can learn by watching as you have fabrication skills way beyond me :)
Andres Barquero Well, since I had to get the new camera there really was no reason not to record in 720P at the very least.
I’ve heard stories of old timers filling the tank with steel shot or bearings and strapping it to a tractor tire and going for a drive lol
lol your tank dance skills are pretty sweet aaroncake
nice work
I've been looking for a video that shoes all the steps and how to do them without taking forever and making me want to poke my eyes out. Found it. Pluss it was like the "Wayne's World" version. Very nice job and thank you. Party on, dude.
Good job! Luvitt at 12:18
Had to subscribe to You! your humor is impeccable. If you don't know Comedy vary well you won't spot it. I love a funny mechanic. New Fan Here Buddy
Fantastic to watch, it's starting to look great. Just wish it wasn't so long between parts :-(
hot dam that's a lot of work.
You're awesome Aaron. I've been checking on your videos for a couple years. Usually I binge watch in my spare time. It's really cool to see someone like yourself! I'm happy to see that you are still working on this project with no plans of quitting! Can't wait to see the next video! Thank you!
You're video much better than other videos on this subject. I think Por15 has zinc in there phosphoric acid prep solution. Leaves zinc phosphate film. Don't know how much better this is than using only phosphoric acid.
Correct, the Metal Prep / Metal Ready is a phosporic acid solution with zinc ions. It leaves a zinc coating. I have some bare metal (the blasted engine bay of the car) which was treated with Metal Ready 8 years ago and is still 95% rust free.
Great job man. Very informative video.
20.41. 🤣
i Just watched the whole video of that, and i gotta say,.. imma try that one day, that cardio though
This was a great video... It inspires me to keep going on on my 1988 FC. Thank you Mr. Cake!
Nice job bro
HAVE A HAPPY CHRISTMAS ARON
What a genius 👏👏👏
Good tip for shaking the tank. Instead of doing it by hand, strap it to the front of a small cement mixer. It revolves smoothly and you can adjust the angles so all the tank gets covered.
That is brilliant. Now, off to find a cement mixer for next time...
In the last 3 day I watched all 38 episodes.
I liked to see your home febricating and detailed filming/editing.
Keep up the good work, i'm subscribed
Cheers form the Netherlands!
Aarocake adoro seus vídeos e percebo que como é bom profissional faz questão de ser detalhista sem pressa de fazer um bom trabalho tenho melhorado bastante profissional sou reparador de empilhadeiras aqui no BRASIL nas horas de folga mexo em carro como hobby Grande abraço.
Leotube309 Thank you! This is my hobby as well. In real life I'm a computer tech.
love the way you cleaned your lens! I bet the 'ol botty puckered up when you realised you had douched your new cam!
Well done and it looks like you have good water pressure. LOL
Eric Corse That stupid hose is very soft so it functions like an accumulator. Handy sometimes. Other times, well, we get what happened in the video.
Been waiting for a new vid!
Awesome work :)
Edit:
Dude that part at 12:10
:) Lmao haha
Amazing episode as always great to see you in HD! hope you get more viewers and subs you deserve a lot! great work.
I love your cosmo series aaron! When i saw you tai-chiing the Tank, i kinda thought of some suckling pig machine for rotating it😂
That is a very specific comparison.
Meditation fuel tank Tai chi. I gave you a like in that moment.
Considering that tank is in the trunk and is now coated inside and out with POR15 products, if it EVER rusts through, I'll be amazed.
Just a little tip. you may prefer to use a drywall sanding block for paint prep, they conform to odd shapes and are usually made with a 300gr side and a 150 gr side, they work flawlessly for me.
Ronald Colman Ah yes, I have used those before. I didn't have one on hand in the shop because I decided to paint the exterior of the tank as a spur of the moment decision. Took a look at it with all the damage and residue from coating the inside and figured the outside should look as good as the interior. So I just grabbed what I had on hand and started sanding. 150 grit really did the job in a few minutes.
Bang up job too, I just figured I would share something that has worked well for me. Keep the episodes coming....
12:18 is worth the price of admission
Bahahahahaha
Once again good job Aaron! I'd be able to enjoy it more if I didnt get my megasquirt stolen with my POS car (I was using the car as a test bench for my MS3x I told you about and now everything is gone).
Gives me a smile to watch your vid though!
Yoan Carlove The entire car was stolen?! I hate thieves. I mean, I REALLY hate thieves. There are some countries which have the right idea for dealing with thieves: cut their hand off.
I agree, yes they took the POS to part it out probly, I had the turbo behind the back seat aswell as some LS2 coils for COP and all my electronic hardware and tools including the innovate LC2...
The irony is, I was working on DIY code pad with some on-off-on switches to wire in the ignition but I didn't complete it.
Yoan Carlove That sucks even further. Guess it's time to install cameras. Maybe keep an eye out on local forums for your parts.
sweet man, glad to see yet another video of yours, keep em coming plz
THANKS YOU for all the REALITY of making a how to & how NOT TO Video....LOL Its something i'm planning to doing soon ..& now i see all the steps I'm in for ....Really twice ? @ 4.00 ,13.53 .. Nasty., use a longer hose & always blow 1st, Best video i've seen using Por 15....Peace
Nice 👍🏼
Party on Wayne!
holy cow,,, a lot of shaking going on Thanks
He deserves a sub and like after that full send syphon on the tank @ 3:45
Well thank you!
Aaron,
Siphoning, there is a better tasting way.
You should have an air compressor and a dusting pistol in that shop of yours.
Put one end of your syphon hose into tank as usual, place the other end lower than the tank.
Taking your dusting pistol, place it at the end of the hose just behind the opening pointing in the direction of the hose, pull the trigger.
The compressed air from the gun creates a low pressure at the hose opening ie suction and it will pull the required fluid down the hose, all without insulting your taste buds or causing odema in your lungs if you were to inhale something like fuel or acid with your current method.
You zlso have impressive water pressure in your shop, you owe me a beer and a dry keyboard.
Nice work on the rx5 I havent seen one in decades.
Cheers
Excellent practical use for Bernoulli's principle. Good idea. I'll keep that in mind next time.
White vinegar clean really well
Holy crap hahaha! You made me fart a bit when you accidentally sprayed water everywhere! The look on you face! 😂😂
Top quality work Aaron.
Aaron, thanks for the awesome videos they are really informative and great to watch!
I am doing a similar restoration on my rx7 fuel tank, and I am curious as to why you chose Por-15 fuel tank sealer over some of the others (caswell, red-kote or Eastwood)? I have heard of some issues with the Por-15 peeling over time and clogging fuel pickups but have no experience with any of the products.
Also thank you for the information on the fuel pump electrical connector from racetronix, I have been searching for a product like this for a long time!
Dansyoung Primarily because I have fairly extensive experience with POR-15 products and in my experience they have always worked as advertised when the instructions are followed. And that's the key. It's no joke that I made reference to the instructions several times in this video. Searching around there are stories of all the coatings failing which is likely more due to improper prep than anything else.
PUT THE LOTION IN THE BASKET!!!!!!!!!!!!!!!!
After traveling into the future with you...i look back into the past and realize we could have had a longer present ,if we would have intalled a fuel cell, lol
I considered it, but the stock tank was actually in very good shape and bolts right in. No reason not to use it really, with a few updates.
I love your wise acre attitude LOL! Very funny but yet informative, and I love the tai chi bit!
You crack me up!
Man damn all this I'm buying a new tank now thanks
Yes, if buying a new tank is an option, then it is certainly less labor intensive.
Question wasn't easier or quicker to split tank in half and then solder back together ? When all done and just needed to prep and seal the joining area ?
diego villanueva I think splitting the seam in a way it could be soldered back would be very difficult. The seam is pinch welded all the way around the tank (likely done with a wheel on a spot welder) which also forms the mounting flange. I'm not sure how a weld like that would be removed without cutting off the flange.
Awesome :)
Hi, thanks for uploading your videos. They're really helpful. I'm doing the same procedure you're on this video. I just had a quick question about the gas tank. My tank is from a 76 datsun. I wanted to ask you, I notice my tank inside has a small cylindrical mesh filter inside that's connected to the metal fuel line.
Would the POR 15 sealer also seal the mesh filter? 😬 there's no way I can cover it or remove it. I was wondering your opinion if your tank also has a filter inside.
Thanks
Yes, it would definitely clog the filter. I'm not sure I have a solution for that however I'm very surprised it is non-removable. My tank didn't have such a filter and even if it did, it wouldn't matter as I have converted it to an in-tank style EFI pump.
In theory you could blow air through the line to try and clear the mesh before the sealer clears though I have no idea how well that would work out.
@@aaroncake Thanks for the advice. Wish I could show you a pic but there's none on google I could find of this tank. If you put the flash light inside you can barely see it. I tried taking it off with a wire that would reach it but didn't work. I guess it was put on when they where welding the tank and meant to be non removable and never to be seen. 👀 I left it on and sealed it up to see what happens. I'll probably end up braking it off if the fuel filter is got sealed also. It wouldn't need it any more I suppose. I'm still amazed how the hell is there a non removable fuel filter built inside my tank.
Thanks Aaron! Keep up the cool videos 😀👍
Nice manly wrist watch. 👍
I've had it since grade 4.
@@aaroncake in that case…nice watch.
Haha, thanks! And no worries. A lot of people comment on the watch.
Hi there, fantastic video I have subscribed and look forward to viewing your other videos, can I ask what you did about the inside of the pickup/return pipes??, did they clog I would like to line mine with por-15?
Peter Clare In my case I didn't care since all of those tubes were pre-clogged and I converted the tank to EFI, so my feed and return lines are now on the pump flange (episode 37 I think). The stock carb lines were very clogged. Couldn't open them up with compressed air. But if you have to preserve those lines, it would be critical to drain all the sealant out of them before allowing the tank to dry. Because if the sealant solidifies inside, there would be no way to remove it unless you have a long flexible drill bit. The larger diameters are likely fine, but the narrower lines (1/8") could be clogged.
