Re: welding a gas tank
When I was prepping for my MPI, I took my gas tank out, it was a poly tank, but I wanted to clean it out. After drainging it and washing it out about 3 dozen times with the garden hose, I left it for a week to let it air dry. I was going to be welding in the rear of the jeep to get some stuck remains of bolts out of my frame and didn't wan't to have any problems. After a week welded, heated, and causes all manner of sparks to fly, with the gas tank still sitting under the jeep with no problems. It seemed safe enough.
