Post 80' model Vette Fuel Tank, How do I fix a leak?

A good friend of mine has an 80' model vette. The fuel tank leaks on the bottom from the looks of it, cause it will leak till its empty. It has a urethane liner wrapped in metal. apparently the metal is only for protection, cause it does'nt look damaged, but it still leaks. Are there any products on the market that will fix a cracked liner? He has looked for a new replacment at Swap meets, Vette shows, ect. and can't find one. He does'nt want a junk yard tank if he can avoid it. Any help on a fix or replacment would be great.

i spent a few years at a rad shop, and what we did with hard to find, hard to replace tanks is this. there is a product on the market, cant remember what its called but i can find out.you clean out the tank as best you can. theres a few tricks for cleaning badly rusted tanks. vent it with a reversed vaccum cleaner to dry it out, then you just poor in this liquid, slosh it around and dump out the xtra. let it dry, and viala. it coats the tank in a plastic skin that lasts for years. hope this helps. if you want me to find out the name, let me know.

You mite go to ecklers.com to see if they have a replacement tank. I bought one for my 69 model for $200.00. If this doesn't work call your local radiator and welding shops to see if they do this type of work.

You can get a sloshing compound from a airport mechanic, they use it for aircraft fuel tanks, it works great, there are some others on the market that will work, but not as well. If its in the lower spot you should be able to pull the sending unit from the top and pour some of the sealer in the tank and have it jacked up on the opposite side for it to flow to the spot. Let it sit a day and it should work.

Kreem Products, Inc. makes a fuel tank liner and sealer kit for motorcycle tanks. you poor it in and swish it all around and it forms a tough white skin on the inside of the tank. I had a tank leaking on an old chopper once and this fixed the problem. not sure if this would be appropriate for a gas tank on a car (bikes hold about 5 gal) but it's $16 a pint, and not sure how many pints you would need. your local auto parts dealer can get it for ya if you want to give it a try.

Eastwood has the tank sealing compound too. I have done half a dozen old swiss cheese rusted tanks with the slosh and it works like a champ.
