Mark IV (man what a boat)anyway we punched a hole in the tank while on vacation we took it off in front of a garage of one them old guys who could fix anything w/ a torch a hammer and a pair plyers long story short he took a garden hose stuck it in the tail pipe of his truck the other end in the empty tank ran the truck for a while to remove all the fumes
and brazed up the hole w/ a torch we sold the car in1981 never leaked
I would never try this myself

but maybe there one of those old guys near you if the tank is still in good shape just a thought Mike

Not that crazy. I fired up the torch 2 years ago to fix my gas tank. It is a polyethelene (sp?) tank that had cracked. I called around an NO ONE had a used one, places on the net don't ship used gas tanks (I wonder why). It was like $600 something at the dealer. It was cracked near the top so as long as I put less than 13 gallons in it I was OK. I tried several things to fix the crack, epoxy putty, epoxy and cloth until I had a genius idea.
I figured that since it was poly, and kayaks are made of poly, I'll see what they use to repair kayaks. The kayak shop had some glue but they said it had to be heat cured. The tank was emptied and sat out in the sun for a week. I took the compressor and blew it out. The original plan was to fill it with water but I got impaitent, and put the torch to it.
None of my patches would hold and the big bonus, I didn't blow myself up. I ended up buying one from a dealer in Phoenix. It only cost me $400 something.
I thought $400 is a lot of money to spend on this 9 year old truck. Then I stopped and thought more, $400 is one payment on a new car! Although it looks like crap, it runs and drives fine. It still gets decent mileage and most important, cold air conditioning.
Doug save yourself the pain and get a new tank. This ordeal went on for about a year and a half till I replaced the tank. Oh it still isn't totally fixed. The filler neck is now leaking. I have to get a new one of those too. It's $125 for a 2 ft long molded rubber hose. This time I'm just dreading having to take the bed off the truck again. If I fill up till the gas pump clicks, it only drips a little bit. I can live with that.
