Never had a prob with my 03, havnt had one with my STi *knock on wood*. But my Kawasaki Jet Ski will sometimes shoot gas out the fill tube when there is still like 10 gallons of free space in it. The Hummer always stops wayyyy short (but that is diesel and seems to be more foamy than gasoline) then you just gotta watch to make shure it dosnt overflow (long process).
