I have a fuel tank off a piece of equipment I want to modify for another piece of equipment. The filler neck is thick wall steel, maybe 3/16, and has no provisions for a cap. Tank is welded steel, not stamped sheet metal. The original design used a rubber hose to connect of the cap. I am wanting to weld a nipple to accept a standard 2inch vented fueltank cap. The tank was just emptied of gas and I am trying to figure out a way to clean it so it doesnt blowup when I stick a welding rod to it. Since the filler neck sticks up above the rest of the tank by several inches, I am thinking about just filling the tank with water to just below where I will be welding, but want to make sure that is sufficient precaution before I proceed. Any advise will be appreciated.
