Vehicle is Difficult to Fill with Fuel or Filling Station Pump Shuts Off Before Tank is Full (Inspect Fuel Tank Vent Tube Opening and Replace Fuel Tank)
2003 HUMMER H2
Condition
Some customers may comment that their vehicle is difficult to fill with fuel or when filling, the pump continuously shuts off before the tank is full.
Cause
This condition may be caused by the fuel filler tank vent opening being collapsed inside the tank, which does not allow fuel vapors to vent sufficiently.
This condition may cause the fuel fill nozzle to shut off prematurely.
Correction
Inspect the fuel filler tank vent for blockage and replace the fuel tank if an obstruction is encountered using the procedure listed below.
1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information in the Service Manual (SI Document ID #928339).
2. Remove the fuel tank vent hose from the fuel tank.
3. Using a plastic tie strap (at least 254 mm (10 in) long), insert the pointed end of the strap into the elbow fitting of the vent and push it beyond the 90 degree elbow in the vent fitting through into the tank. The tie strap should be able to go into the tank at least 203 mm (8 in).
4. If a solid obstruction is encountered, replace the fuel tank. Refer to Fuel Tank Replacement in the Engine Controls sub-section of the Service Manual (SI Document ID #861699).

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
