Fuel Pump Module: Removal

The fuel pump module is divide into 2 sections, upper and lower. To service the check (control) valve, replace only the upper section. To service the fuel gauge sending unit, remove the upper section. To service the electric fuel pump, fuel pressure regulator or primary inlet filter, remove both sections and replace lower section.

This vehicle may or may not be equipped with an access plate. This plate is located on floorpan inside vehicle at rear cargo area. If not equipped with an access plate, the fuel tank must first be lowered to gain access to fuel pump module. 

If equipped with an access plate, fuel tank removal will not be necessary for fuel pump module removal. Access is from rear cargo area. 

1. Four cargo hold down clamps are located inside the vehicle on the floor of the rear cargo area. Remove the 2 rearward mounted clamps by drilling out the clamp rivets.
2. Fold carpeting forward to gain access to fuel pump module access plate.
3. Remove 4 fuel pump module access plate nuts.
4. While applying heat from a heat gun, carefully pry up fuel pump module access plate. Take care not to bend plate.
5. Thoroughly clean area around top of pump module to prevent contaminants from entering fuel tank or fuel lines.
WARNING: THE FUEL SYSTEM IS UNDER A CONSTANT PRESSURE EVEN WITH ENGINE OFF. BEFORE SERVICING THE FUEL PUMP MODULE, FUEL SYSTEM PRESSURE MUST BE RELEASED.
6. Release fuel system pressure. Refer to STANDARD PROCEDURE - FUEL SYSTEM PRESSURE RELEASE .
