Gas tank is leaking

Yep, thats right, I thought it was leaking so today I took it out and sure enough its leaking at a spot that the po had patched once before. Anybody got any suggestions about what to use to fix it and where I could get something from to fix it here in S.C.. I would go ahead and put the tank under the bed if I had one handy or hadn't already taken mine out so I could get one from a blazer, But I can't so any help is appreciated.

Re: Gas tank is leaking

Use one of those gas tank sealer kits. They come with a cleaner, etching liquid, and an epoxy coating.

Another option is to take it to a radiator shop and have them seal the inside with solder.

Re: Gas tank is leaking

I just replaced my tank that had been re-sealed. The liner was breaking down due to chemicals in gas. I would just replace it if you can.

Re: Gas tank is leaking

I used an epoxy sealer on one once.I don't remember the nname but I had a leak and no other way to work.It worked even wet(as the label said it would).It held for about 2 weeks before I replaced the tank so I have no idea if it would have worked permanately.It was a 2 part style gummy epoxy.

Re: Gas tank is leaking

I bought some permatex tank sealer. I kneeded it, cleaned the surface real good but it still leaked,I'm going to go ahead and replace the tank as soon as I can. If I use a k5 blazer tank and put it under the bed, do I need a special sending unit or just use the one that comes in the tank?
I know where there is several k5's, 80-90 model year, I guess they would work. Has anybody used one of these?

Re: Gas tank is leaking

Throw it away! It is just going to leak in another spot. Get a good clean used tank and move on.
Check the replacement tank by removing the sender and look inside to make sure it is clean...no rust or crud.
