jan arnett (2) Posted August 8, 2017 Share Posted August 8, 2017 I have a gas tank that someone used a can opener on. I hate to use a flame around a gas tank. I have seen them filled with water or car exhaust but I am not that brave. Any ideas on an epoxy solution or other solution. Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2017 Share Posted August 8, 2017 That looks safe enough to weld. Looks like it hasn't seen gasoline for a long time. When my Mothers cousin had his service station he didn't have access to a steam cleaner so if it was on the bottom, sides or ends he just filled the tank with gasoline and welded it. He never had a problem. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted August 9, 2017 Share Posted August 9, 2017 (edited) You can open it up and pressure wash it and it will be perfectly clean. If there is rust inside, sandblast it. Get it clean, clean, clean and weld or braze the cuts. You will need to do some hammer and dolly work to get everything straight. When it is welded up it will have to be coated on the inside with some kind of epoxy or other sealer. The outside will need to be painted. If the tank is exposed to view you can smooth over the welds with body filler as you would a weld seam on a fender.

Guest Posted August 9, 2017 Share Posted August 9, 2017 He was often repairing a tank that was still on the car. He would just make sure the tank was absolutely full and then he used an acetylene torch to braze up the hole or holes as the case may be. As long as the tank was full there was no danger as gasoline needs to be vaporized to burn or explode. I always worked for him. After the first two or three times I even stayed in the shop and watched him. Link to comment Share on other sites More sharing options...
