I have an old gas tank off of a motorcycle that needs a mounting tab tacked on to it. When I emptied the tank, the gas was real old and smelled like varnish so i flushed the tank with acetone (rusty in there), then rinsed it out with soapy water several times. I dont think it would explode because of the age of the fuel that was in it and it was thoroughly rinsed but i'm not a big fan of blowing my fingers off my body so i'm a bit relunctant to mig this thing. A friend suggested to go outside with the cap off and stick a propane torch in the opening and see if it flashes. If it doesn't, it most likely wont explode. Any comments before I muster up enough nerve to tack this tank.
thanks in advance, walt
