FUEL PRESSURE REGULATOR REPLACEMENT

REMOVAL PROCEDURE

1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure.
2. Disconnect the fuel pressure regulator vacuum line.
3. Remove the fuel return pipe from the fuel pressure regulator.

4. Remove the fuel pressure regulator screw.
5. Using a shop towel to catch any spilled fuel, lift and twist the fuel pressure regulator in order to remove the fuel pressure regulator from the fuel rail.
6. Remove the retainer and the spacer bracket from the fuel rail and discard.
7. Remove the fuel pressure regulator inlet and the fuel return pipe O-rings and discard.
8. Inspect the filter screen for contamination, if contaminated replace the fuel pressure regulator.

INSTALLATION PROCEDURE

1. Lubricate the fuel pressure regulator inlet and the fuel return pipe O-rings with clean engine oil.

CAUTION: Connect the fuel return line before tightening the regulator attaching screw in order to prevent the regulator from rotating. Rotation of the regulator could damage the retainer and spacer bracket and lead to a fuel leak at the regulator inlet.

NOTE: * Do not use compressed air in order to test or clean a fuel pressure regulator as damage to the fuel pressure regulator may result.
* Clean the fuel pressure regulator filter screen with gasoline if necessary.
* Do not immerse the fuel pressure regulator in a solvent bath in order to prevent damage to the fuel pressure regulator.

2. Install the fuel pressure regulator inlet and the fuel return pipe O-rings.
3. Install the fuel return pipe to the fuel pressure regulator.
4. Install the new retainer and spacer bracket into the slot on the fuel rail.
5. Install the pressure regulator to the fuel rail.

NOTE: Refer to Fastener Notice in Service Precautions.

Tighten the engine fuel return pipe nut to 17 N.M (13 lb ft).

6. Install the fuel pressure regulator screw.

Tighten the screw to 8.5 N.M (75 lb in).

7. Inspect and verify that the retainer and spacer bracket is engaged in the slots in the fuel rail. Grasp and pull on the regulator to ensure that the regulator is properly seated.
8. Connect the fuel pressure regulator vacuum line.
9. Connect the negative battery cable.
10. Inspect for fuel leaks with the following procedure: 1. Turn ON the ignition for 2 seconds.
2. Turn OFF the ignition for 10 seconds.
3. Turn ON the ignition.
