Watching you build a tank from scratch gave me confidence to build my own. Didn't come out as amazing as yours but it was my first and I'm very happy with it and I'm sure my next one will be better. Thanks for sharing your experience and skills
Thanks for the tour and info. The 3a I just got has a plastic tank. Repro I guess. What I don’t like is it pulls fuel from the top through a tube vs a drain from the bottom. I’m thinking that 6-8” of vertical draw the mechanical pump needs to overcome isn’t exactly ideal or designed for. Luckily the box of parts I got along with it includes the original tank. Looks a bit henky along one seam but thanks to this video I’m going to try to clean it out and address any leaks.
I just cleaned out my CJ2a tank and had EXCELLENT (like new) results with using a gallon of muriatic acid (hydrochloric acid diluted for use in modding the PH in swimming pools) and 5 gallons of generic white vinegar (acetic acid). I left that solution in the tank for a couple hours, turning the tank numerous times to ensure full coverage of the internals. I drained it and rinsed it out with water and baking soda to neutralize the acid, then set it up in the sun with a heat gun stuck in to the filler neck running full bore. The tank was dry within a half hour. It looks flawless on the inside now. The acid ate ALL of the rust as well as all of the chunks of varnish. Super happy with the results.
I have a clogged fuel tube on my 3A. How is the best way to clear it? I have run a piece of wire into the tank about 7”, but still won’t allow fluid flow.
usually when the line from the tank gets clogged it means there is junk in the tank. You can pull the cap off the tank and blow thru the line from the fuel pump side with air to dislodge the clog but it may come back again if there is junk in the tank.
@@metalshaperJeep Thanks for the reply! I had drained the tank of the old fuel and put fresh in it. hoping that it might free it up. The drain plug was not occluded and drained well. Not much "junk" came out. I tried blowing through the line and could not get any air to go through it. I have run a piece of bailing wire backwards into the u-tube about 7", then it bottoms out. I'm assuming i am hitting the bottom of the tank. Iam in the process of re-draining the tank and removing it. I have a new sender unit to put in it, after I get it to flow fuel. I was wondering if the baffle is between the sender unit opening and the outlet u-tube? I will try working a wire into the drain plug hole and see if I can dislodge whatever is plugging the u-tube.
Any idea where to find a tank for a 1967 CJ5 with the Dauntless V6 which has a vapor return line that goes into the top of the tank near the filler tube neck? The only tanks I can find don't have the vapor return.
Good question. I have the same Jeep but the original is long gone and a newer {custom aluminum} tank has been relocated to the rear with a custom filler in the bed. Blehh. Looking to restore the tank to the under-seat spot
After soaking with lye for several days and getting old varnish out of the side with sending unit, how do you get old varnish out from other side of baffel?
My tank has varnish from old gas as well, but it doesn't seem to be as bad as yours. But I do still have specks of Varnish on the inner walls of the tank. It's a pain to remove. Do you think it's okay if it's left there? It doesn't seem to want to come off. Oh, btw, I used dawn soap to clean it out as best as possible.
any remnants left behind will eventually work loose and get into your fuel system. Run a filter and change it often if you can not get your tank clean.
@@metalshaperJeep Yeah, I'm in the middle of replacing parts because I did start up my truck a long time ago with old fuel. At first it was idling around 500 rpms and eventually it just didn't want to start up anymore. I removed the injectors and they do look like they are clogged up from the varnish, I'm not certain about the fuel rail and fuel lines. After that is when I dropped the tank and started removing the varnish.
Yes all that junk in the tank was old fuel. That was one of my worst thanks and that is why I showed it. Just wanted to show that even the worst tanks can be fixed.
Hello, i have a stupid idea! Do you see that plastic pieces that are made inside a rotating molde heated with open flames? The plastic pellets are inside the fuel tank, rotating and heated, living a coat of plastic inside. Using the same kind of plastic used on modern tanks of course.
My CJ2A has a homemade tank, I'll replace it someday, I bet I got 5 pounds of varnish out of it. It was horrible smelling crap. I eventually got it cleaned out, but man what a mess.

Glad to hear it!

good tips, and glad you were able to save an original tank.
I'd like to see more of that 2a from what I could see it looks mint. Cheers
I have a Willys Kaiser 1960 CJ5 jeep no gas tank --do you have a old one that i can soak and use ?

Brain how much lye are you using for a CJ5 tank ?

good video useful stuff for sure but are you sure is old fuel varnish and not old tank liner

Great channel I have a 72 cj in a lot of parts did not take it apart so I need help
Great video!
Thanks Oli, glad you liked it. Much more coming so keep watching.

Does the reproduction tank have a baffle?
yes, there is a baffle in the reproduction tank.
i used small sharp stones after lye
Lol... first 4 minutes repeats itself. Good info though.
bom
filipino tank is better than chinese tank
I don't like either of them. On my personal projects I use original fuel tanks or build one out of quality materials. fuel tank build video coming.
