Gas Tank Leaks
Hi, Vinrum.
I once welded up a gas tank out of a small Found On Rubbish Dump (Read the initials.) car that had had a disagreement with stump hidden in long grass. The thickened section that the drain plug screwed into had been almost torn out of the bottom of the tank.
I took the tank right out of the car, removed the actual drain plug, connected the tank to the car exhaust with a bicycle tube, rigged an alternate fuel supply and ran the car exhaust into the fuel tank. I found I had to cut a few small holes in the tube to enable the car to run. This was because once I had bent the torn piece back into place in the tank, there wasn't enough outlet for the exhaust gas to allow the engine to run.
I did the actual welding with an oxy-acetylene torch and ordinary black wire welding rod. The tank never leaked again while I had the car which was about another 15,000 miles or 12 months.
I do NOT recommend this method. All I am saying is that it worked for me. It is supposed to work by removing all the combustible oxygen form the air inside the tank and replacing it with supposedly non-combustible exhuast gases. I obviously did something right 'cos I'm still here to tell about it. Get this method wrong and you may well be shaking hands with Saint Peter and signing the register at the Pearly Gates.
I was 25 when I did this. Thatsa lotta years ago. Surely there must be some other tricks for doing it now like the one mentioned in the post above.
You have a wonderful day. Best wishes. Deas Plant.
