Question for you guys. I was installing my fuel tank today and bending the flanges to parallel on the tank to make for some more clearance. When I was bending one area, I heard a 'pop'...wasn't sure if that was the metal expanding or maybe it was the plastic liner, or possibly the 'weld'? I didn't see any visual damage and the rest of it bent fine, but when looking at the stamped seal around the tank, is that really a weld or is the tank stamped together in some way? Doesn't seem like that could make a pop like I heard, but thought I'd inquire with you guys.
