To replace the fuel pressure regulator, start by relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. Then, remove the engine cover and, on certain engine models, the upper intake manifold. Next, remove the pressure regulator retaining clip and detach the fuel pressure regulator from the fuel meter body or fuel rail. If replacing the regulator, bring the old regulator and retaining clip to the store to ensure you get the correct replacement. Replace all of the pressure regulator O-rings, including the smaller one that may still be in the fuel meter body or fuel rail. Disconnect the vacuum line from the regulator and remove the retaining clip and regulator. Make sure all spacers and O-rings are removed from the fuel rail. Lubricate the new O-rings with oil and then proceed with the reverse of the removal process for installation. Note that on 2004 and later models, the fuel pressure regulator is not serviceable as it is an integral part of the fuel pump module.

To remove the V6 fuel pressure regulator, start by relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. Then, remove the air intake resonator and clean any dirt and debris from around the fuel pressure regulator and fuel lines. Disconnect the fuel pressure regulator vacuum line and unclip the engine wiring harness at the front of the engine. Next, disconnect the fuel return line and remove the retainer. Finally, remove the fuel pressure regulator mounting screw and remove the fuel pressure regulator. For installation, start by installing a new o-ring and lubricating it with clean engine oil. The remainder of the installation is the reverse of the removal, and make sure to tighten the fuel pressure regulator screw to the torque specifications. For the V8 model, the removal process is similar, starting with removing the air intake resonator and cleaning any dirt and debris. Disconnect the fuel pressure regulator retainer clip and remove the fuel pressure regulator. For installation, install a new fuel pressure regulator retainer clip and follow the reverse of the removal process.
