Angry Follow up on removing pour in gas tank liner

I give up, 4 gallons of acetone soaking for 2 weeks, a week in a radiator shop in the hot tank and another day full of muratic acid. So far about $150 in materials not to mention the time without a running car. I looked in it today with a lighted fiber optic scope and to my dismay, more loose lining that is still peeling. I'm done. I found a good tank for a reasonable price and I'm going that direction. NEVER USE POUR IN TANK LINING!!!!!!

I hate it for you, and I have heard of similar stories from others. The only thing is, how do you know the replacement tank is good inside?

Brent.. Aren't you the one who cuts up tanks to expose the inner baffles for cleaning?

I've been told several times that sealing the tank should be done.
Mine has some old seepage around the column bracket.

I am assuming that this is something that would have to be done exactly right or the problem being encountered here would be expected. If something can be done wrong some one will do it.

Is it never done succesfully? What is to be done for seeping at seams or at the steering bracket.
I'm all ears.

There are various levels of repair.

Best; cut open the tank, remove the old solder and rivets. Re-rivet and solder to seal.

Next best; go to a '31 style bracket and the sand and seal the area where it is seeping.

Not so good; just sand the seeping area down and use jb weld to seal it, and don't use the steering wheel to help yourself into the car.

Here is follow up. I poured 1 gallon of acetone into the tank and watched as the sealer began to curl up. This is not going to be that hard to do, rest assured I'm doing it outside too. The cap is off the tank and I have it sitting on an outdoor rocking chair so I can rock it back and forth to agitate it. I'm guessing 3 or 4 gallons of acetone and a couple of days and the problem will be solved. I plan to take it and power wash it and the possibly still hot tank it at the end. I will then follow up with a couple of gallons of evaporust. Then all I need to do is paint. Must admit I'm feeling a little better about this issue.:::Quote


A big turn around from your last thread and post,,, at least you tried..

Maybe you can cut open the tank and restore it as a test project

I've had luck removing tank sealers with MEK or paint remover. I'm not sure if acetone is strong enough.

My tank was sealed when I bought the car. So far it is holding up fine. I'm not sure there are any baffle in the tank. With the tank low on gas I can look in with a match ha ha a flash light and the bottom and everywhere I can see looks perfect. I don't see any baffles. Whoever did it used the right stuff.

use jb weld to seal it
Be careful using JB weld to seal gasoline. I've had ethanol laced gas soften up JB weld, but I've heard, but can't confirm that newer JB weld is OK to use.

look in with a match
I was told years ago not to use a match to look in a gasoline can as it's not safe. Use a lighter instead.
YMMV, smiles, Ken

About your signature ...

That should not be problem with the new "gasoline" if it is 6 months old!

My snow blower would not start ... drained "gasoline from the tank and carb bowl and replaced with fresh, worked fine.

Poured old gas on the ground and tossed a lighted match to it .... It would not burn!

Wonderful products through "modern chemistry" !!

1929,
It is a rubbery compound which is 'poured' into a clean, empty fuel tank. Then sloshed around, shaken, tumbled until the inside of the tank is covered with the stuff. Left to dry and the tank refitted.
Used as a bandaid repair for a leaking fuel tank. Works great for a while, if you are lucky. Works very well, if you are very lucky, but normally dont last for ever.

I used the Bill Hirsch sealer over a year ago, so far no problems. What problems can I expect to eventually happen?

I bought my car already restored, and noticed later that it had the tank sealed with type of white product. I was very concerned, as I had heard stories about coating deteriorating and peeling off. I have now had the car for 10 years, and this was done several years prior to that, and it has only had "crap" gas in it all these years. Absolutely no sign of it sloughing off or peeling, and no clogged fuel lines or material in the sediment bowl.

I put mine in 27 years ago and it has not caused any problems. It was sold by a local firm here in NZ: "Veteran and Vintage Cars Ltd".

A warning about the older tank sealers. Some of those made before ethanol gas were soluble in the stuff. How do I know? I spent a lot of time cleaning out my carb, manifold, cylinders, and valve chamber.
