To remove and install the module, the entire assembly must be replaced as none of the components can be replaced individually. Start by relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. Then, raise the vehicle and secure it on jackstands. Remove the fuel tank and clean the area around the fuel pump/fuel level sending unit to prevent dirt from entering the tank. Mark the position of the arrow on the fuel pump module for proper installation. Use pliers or a hammer and brass drift to loosen and unscrew the lock-ring, and carefully remove the fuel pump/fuel level sending unit module from the tank. Inspect the large rubber gasket sealing the mounting hole and replace if damaged. When installing the module, align the embossed arrow properly. The installation process is the reverse of removal.

To perform a fuel pressure check, relieve the fuel system pressure and connect a fuel pressure gauge to the Schrader valve test port on the injector fuel rail. Start the engine and check the pressure on the gauge. If the fuel pressure is not within specifications, check for restrictions in the fuel system or replace the fuel pump module.
