JB weld and gas tanks

[wills 51]

Has anybody used this stuff on a gas tank and how well does it hold up? I have a small leak where the fuel line goes in on my 50 desoto .....

I have not personally used a cold weld to fix a gas tank leak, but know people who have. Myuncle has done small leak repairs with J B Weld, then he would go over the JB with metal to metal filler, he said it sealed up the leak.

Hopefully others will chime in, you could also remove the tank, good opportunity to clean it up and then have the leak soldered in a shop..................good luck Fred

I used it a few different times on cement mixers, works great on them, I think they vibrate more then in a car. Tony C

I had an occasion to use this as described...I had a hole in the tank..someone wanted some gasoline..I cleaned the area real well..placed a layer of JB, then screwed a self tapping screw with a large enough body to fit the hole..the screw had a large washer that was also coated in JG weld..tightened it up..placed a small coat of JB to smooth it all over..never dripped a drop..

In an old Corvair, gas tank in the front, I drove over an ice pile getting into a parking space lot and creased the tank - leaked out most of my gas overnight. JB weld fixed it (even while dripping gas) and held up for the next two years. (that's when I junked the car, gas tank still ok)

I have heard that JB weld works well on Corvair radiators too:cool:

Don, I heard somewhere that those Corvair radiators, never did leak! Tony C

My girlfreinds dad fixed her transmission with jb weld. There was a hole in the bottom of the case, so he pulled it and filled it with jb weld, it has held for 5+ years without any problems.

I cleaned out my tank, and found it had a few pinholes. I used my welder to fill them(cleaned the heck out of the tank, flushed filled etc) and covered them with a little JB. Looks good and held up. I don't think the welding was needed, JB would have been sufficient. My tank on my International was chemically dipped, and had two pinholes. I used redcoat on the inside, no leaks either.

My tank had a little seepage up on the left side. I made sure the fuel level was low, lightly sanded the area and wiped with lacquer thinner, put on a film of JB and no more leaks. Best to let it cure 24 hours before using.

looks like the consesus is yes it can work. I like the self tap screw idea.
