What I did was mostly an experiment and my first time welding a gas tank. I thought about purging it with argon, but since I can't see argon and fuel vapor, having water I can actually see and know for certain how much vapor had been displaced, I did it that way. I do need to set up my tig to be able to back purge for welding stainless in the future, but with my current regulator set ups, it was easy enough to grab the water hose.
Again, I'm not saying anything I did was the best way. I was just sharing to show that welding on a used tank isn't the explosion hazard a lot of people think it is.
