Repairing a gas tank AFTER you put gas into it, using a torch
Remove as much fuel that you can, don't worry about all of it. Take a length of hose that will fit into the filler. Insert the other end into a exhaust pipe of a gas burner, making sure the exhaust will flow through the hose and into the tank. Let run until the gas tank gets as hot as the exhaust. Liquid gas will not burn, only the fumes. Once the tank is hot (about 10 minutes), let cool to handle it. Now you can braise, weld or whatever. When, back in the days of the dinosaurs, we had steel gas tanks...that is how we repaired them....I have never had a tank so much as go poof putting a flame to them. The CO2 from the exhaust kills the firing properties of gas.
