Why are you changing it? Here is the service manual info.

Fuel Pressure Regulator Replacement
Removal Procedure
Tools Required
J 34730-1A Fuel Pressure Gauge
J 37088-A Tool Set, Fuel Line Quick Connect Separator





Caution
Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.


Disconnect the negative battery cable.
Relieve the fuel system pressure. Refer to the Fuel Pressure Relief Procedure .
Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
Lower the left muffler (auto trans equipped vehicles only). Refer to Muffler Replacement in Engine Exhaust.
Clean all the fuel filter/pressure regulator connections and the surrounding areas before disconnecting the fuel pipes in order to avoid possible contamination of the fuel system.
Disconnect the fuel feed pipe quick-connect fitting (1) from the fuel filter/pressure regulator (2). Refer to Quick Connect Fitting(s) Service (Plastic Collar) .
Disconnect the fuel return pipe quick-connect fitting (4) from the fuel filter/pressure regulator (2). Refer to Quick Connect Fitting(s) Service (Plastic Collar) .



Remove the fuel filter/pressure regulator bracket mount nut (2).



Disconnect the fuel feed pipe (3) from the outlet side of the fuel filter/pressure regulator (2). Refer to Quick Connect Fitting(s) Service (Metal Collar) .



Remove the fuel filter/pressure regulator and bracket (1) from the stud (3).
Cap the fuel pipes in order to prevent possible fuel system contamination.
Disconnect the fuel system ground strap.
Remove the fuel filter/pressure regulator from the bracket.
Installation Procedure




Remove the protective caps from the new fuel filter/pressure regulator.
Install the new plastic quick connector retainers on the fuel filter/pressure regulator tubes. Install the new retainers in the same positions as on the old fuel filter/pressure regulator.
Install the fuel filter/pressure regulator into the bracket.
Connect the fuel system ground strap.
Remove the caps from the fuel pipes.
Connect the fuel feed pipe (3) to the outlet side of the fuel filter/pressure regulator (2). Refer to Quick Connect Fitting(s) Service (Metal Collar) .



Install the fuel filter/pressure regulator and the bracket (1) to the mounting stud (3).



Engage the anti-rotation tab (3) of the fuel filter/pressure regulator bracket (2) into the hole of the tunnel reinforcement (1).




Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.


Install the fuel filter/pressure regulator bracket nut (2). Tighten
Tighten the fuel filter/pressure regulator bracket nut to 4.5 N·m (40 lb in).





Connect the fuel return pipe quick-connect fitting (4) to the fuel filter/pressure regulator (2). Refer to Quick Connect Fitting(s) Service (Plastic Collar) .
Connect the fuel feed pipe quick-connect fitting (1) to the fuel filter/pressure regulator (2). Refer to Quick Connect Fitting(s) Service (Plastic Collar) .
Raise the left muffler (auto trans equipped vehicles only). Refer to Muffler Replacement in Engine Exhaust.
Lower the vehicle.
Tighten the fuel filler cap.
Connect the negative battery cable.
Inspect for leaks.
Turn the ignition switch ON for 2 seconds.
Turn the ignition switch OFF for 10 seconds.
Turn the ignition switch ON.
Inspect for fuel leaks.
Program the transmitters. Refer to Transmitter Programming/Synchronization in Keyless Entry.
Perform the idle learn procedure. Refer to Idle Learn Procedure .

I have 75,000 miles on the car and its never been changed. Figured its about time.

 

Thanks for passing along the tech info.

One thing neither covers though is how you relieve the pressure in the system? The tech tip says to do it at the fuel rail. How's that done?

 

With the car off. Take off the gas cap. Then on the fuel rail you'll see a shrader (sp) valve (looks like a tire valve stem) Cover it with a rag and push in the stem relieving the pressure..
