Fuel Pressure Regulator: Service and Repair

REMOVAL

CAUTION:  To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing the fuel system
Components.

CAUTION:  After relieving the fuel system pressure, a small amount of fuel may be released when servicing fuel lines or connections. Reduce the
chance of personal injury by covering the fuel line fitting with a shop towel before disconnecting the fittings. The towel will absorb any fuel that may
leak out. When the disconnect is completed, place the towel in an approved container.

NOTE:  Compressed air must never used to test or clean a fuel pressure regulator, as damage to the fuel pressure regulator may occur.

NOTE:  To prevent damage to the fuel pressure regulator, do not immerse the pressure regulator in solvent.

1. Depressurize the fuel system. Refer to Fuel Pressure Relief Procedure. 
2. Disconnect the negative battery cable.
3. Remove the fuel pump relay.

4. Disconnect the vacuum line form fuel pressure regulator.
5. Remove the fuel pressure regulator retaining screw.
6. Remove the fuel pressure regulator retaining bracket.
