It is in the fuel tank. The tank can be lowered by first removing the shield, disconnecting lines, hoses, and electrical, and lowering, moving rearward as you go. It helps to tilt the rear of the tank down, and once you clear the axle, you can lower the front. If it has a decent amount of fuel, it also has a decent amount of weight and instability. It is not always possible, but draining the fuel is the best tip I can give.

Need help
My 2003 H2 Hummer is stalling as if the fuel is the issue so I changed the filter and I listened to the pump running so I ruled that out , could it be a bad fuel pump In my experience the pump goes out it stays out maybe I'm wrong
after it stalls it starts up again sometimes right away or it takes a few min. and there's no service lights popping up either
I was told that it could be the ignition switch whats your take on this
since Ive been on the net I see other hummer owners with this issue but so far no solutions
thanks, Ray Harris
ps. solve this issue and ill show u what a donation should look like

Ray:
I would suggest checking the fuel pump pressure when the vehicle dies and won't restart. I have dealt with what we call "a lazy pump" which basically means the pump can't keep up with the demand. They usually have low fuel pressure. Check that and let me know what you find.
