I have pulled the fuel tank on my 'Cuda, it has set for years. What do you recommend to clean the inside?

There does not seem to be any rust, just a "varnish" smell. It might not be a problem, but don't want to take any chances.

Thank you for the information! The easiest solution is probably just buy a new tank.

Before I do that, I am going to try something my local parts house suggested, using E 85 ethanol blended gas.

I put 3 gallons of E 85 in the tank. I have sloshed it around in the tank and will do that for a few days. The theory is the alcohol will help break down the "varnish" buildup. I guess I will find out!

Thanks

When I cleaned mine I used some mineral spirits and some tumble stones. Placed them in the tank and shook it around, let it set for a bit and repeat. It helps if you can get an extra set of hands to shake it around.

I haven't had any issues.
 
Thanks, Bruce. I may try that after I drain the E 85 and see what it looks like.

I put air through the fuel line. It was clear, no junk in it at all, that is a plus.

I mixed some naval jelly with acetone and like bad sport did I put some small gravel in there and shook the crap out of it. After letting it sit I pressure washed the crap out of it and dried it real good.
 
I've always heard to use denatured alcohol.

Only time I did it was due to someone putting a gallon of sand in my gas tank....

Yep, acetone or laquer thinner if you don't have rust or flakes.
It will cut that varnish right now.

I don't think the alcohol is going to do it very well.
 
I took the sending unit out and cleaned the tank with the E 85 plus Simple Green and soap and water. It is to far gone, so I ordered a new one.

No sense taking a chance ruinning a rebuilt #'s matching engine. One less thing to worry about.

The project continues!

When my tank shat the bed I bought my new one from hot rod city garage. It was a work of art.
 
Tank came in today. I have it set up and ready to install.

I read somewhere about using the old seal ring as it was probably thicker then the new rings. They were right!

I used the old seal ring, it was quite a bit tighter fit then the new one. I did not want to take and chances of a fuel leak.

It will be installed on Sat. Next week, the exhaust will be installed, and then I will fire 'er up! For the 2nd maiden test drive, 45 years later! I am pumped!

In most cases i think the OE ring is thicker.
