Fig 2 Fuel Pump Module Components -- Typical:

NOTE: The fuel filter/fuel pressure regulator is located on top of fuel pump module.

NOTE: Two different types of filter/regulators are used.
- If a rubber grommet is located between the bottom of filter/regulator and top of fuel pump module, it can be serviced separately. Refer to the following procedure.
- If this grommet is not used, it cannot be serviced separately The Fuel Pump Module assembly must be replaced. Refer to Fuel Pump Module Removal/Installation for procedures.

WARNING: The fuel system is under a constant pressure, even with engine off. Before servicing the fuel filter/fuel pressure regulator, the fuel system pressure must be released.

TIP: Fuel pump module removal is not necessary.

REMOVAL
1. Drain fuel tank and remove tank.
- Refer to Fuel Tank Removal/Installation.

2. The fuel filter/regulator is pressed into a rubber grommet.
- Remove by twisting and pulling straight up (Fig. 23).

CAUTION: Do not pull the filter/regulator more than three inches from the fuel pump module. Damage to the coiled fuel tube (line) may result.

Fig 24 Plastic Tube And Snap Ring -- Typical:

3. Remove the snap ring retaining the convoluted tube (cover) to the filter/regulator (Fig. 24). Slide the plastic tube down the fuel tube to clear the fuel tube clamp.

Fig 25 Fuel Tube And Clamp -- Typical:

4. Gently cut the old fuel tube (line) clamp (Fig. 25) taking care not to damage the plastic fuel tube. Remove and discard the old fuel tube clamp.
5. Remove the plastic fuel tube from the filter/regulator gently pulling downward. Remove filter/regulator from fuel pump module.

Fig 26 Tightening Fuel Tube Clamp -- Typical:

INSTALLATION
1. Install a new clamp over the plastic fuel tube.
2. Install filter/regulator to fuel tube.
- Rotate the filter/regulator in the fuel tube (line) (Fig. 26) until it is pointed to the drivers side of vehicle (Fig. 22).
3. Tighten line clamp to fuel line using special Hose Clamp Pliers number C-4124 or equivalent (Fig. 26).
- Do not use conventional side cutters to tighten this type of clamp.
4. Slide the convoluted plastic tube (cover) up to the bottom of filter/regulator and install snap ring (Fig. 24).
5. Press the filter/regulator (by hand) into the rubber grommet.
- The assembly should be pointed to the drivers side of vehicle (Fig. 22 ).
6. Install fuel tank.
- Refer to Fuel Tank Removal/Installation.
7. Check for fuel leaks.
