Had a mate try to weld an aircraft fuel tank after filling it with water and emptying it numerous times, then filled it almost full and tried to weld a spot near the filler hole. There was a loud "POP" and a jet of blue flame from the filler hole, which just missed taking off his eyebrows and cleaned out all of the spiders in the garage ceiling...
Old fuel containers can be very surprising!

Used to frequent an exhaust centre who regularly welded up fuel tanks and jerry cans - trick is to not just rinse and fill with water, but to use detergent in the mix - breaks the surface tension of the fuel and gets into all the nooks and crannies. He never lost an eyebrow doing it that way.
