Fuel Pressure Regulator Removal and Installation

PROCEDURE


See the warnings at the beginning of the Fuel System Pressure Relief section.
1. Relieve the fuel system pressure (see section Fuel System Pressure Relief).
2. Disconnect the negative cable from the battery.

If the vehicle's stereo system is equipped with an anti-theft code, make sure you have the correct code to reactivate the unit before disconnecting the battery!
3. On V6 models, remove the access covers from the upper part of the engine assembly (see Engine chapter).
4. Disconnect the vacuum and fuel hoses from the fuel pressure regulator.

5. Remove the fuel pressure regulator from the fuel rail assembly:
a) On 4-cylinder engines, the regulator is attached to the rail with mounting bolts;

b) On V6 engines, an open-end wrench is required to remove the regulator.

6. Install in the reverse order. Be sure to replace the O-ring, lightly lubricating it with clean engine oil before installation. Tighten the regulator fasteners to the specified torque.
7. Check the engine for signs of fuel leaks.
