Several have suggested purging the tanks with Nitrogen. Earl
Use Argon. Greg
I used to weld gas tanks that were removed from cars. The problem is much simpler than any of you are thinking.
First of all purging the tank with any gas is going to leave the liquid fuel intact. This liquid fuel will continue to vaporize. The oxygen inside of the tank will continue to try to equalize itself with the oxygen outside of the tank. This is a simply law of nature. The tank is vented, right? When this happens, you are back right where you started.
The simple solution is to fill the tank with water. With this solution there is no fuel and/or fuel vapor left in the tank and the tank is safe to sand, grind, weld or whatever. When you are done, simply run the water out onto the floor. If you are concerned about not being able to completely dry the tank afterwards, buy a can of gas dry or whatever they call it at the local auto parts store.
