How to remove and install the Fuel Pressure Regulator in gasoline engine on Ford Excursion?

This procedure applies only to 1999 through 2004 models with conventional return-type fuel systems, as 2005 and later models use returnless fuel systems. Begin by relieving the fuel system pressure. Next, disconnect the cable from the negative terminal of the battery. Remove the air filter housing, followed by the accelerator cable and the splash shield. For V10 engines, the throttle body must be removed, and depending on the model year, the throttle body spacer may need to be taken off to access the fuel pressure regulator. Disconnect the EGR vacuum regulator and remove its bracket if necessary. Then, remove the vacuum hose from the pressure regulator. To take out the fuel pressure regulator from the fuel rail, on 1999 models, remove the two mounting bolts, while on 2000 and later models, remove the snap-ring and separate the pressure regulator from the fuel rail. Installation is the reverse of removal; ensure to install new O-rings on the pressure regulator and lubricate them with a light coat of oil before securing the mounting bolts for 1999 models or installing the snap-ring for 2000 and later models.

Ford Excursion Fuel Pressure Regulator

The Fuel Pressure Regulator is found on Ford Excursion and it is required to ensure that adequate fuel pressure is available in the electronic fuel injection process. It is located on the fuel rail and consists of a spring and a diaphragm and is operated through vacuum produced by the engine and the fuel return. This configuration enables the regulator to control fuel delivery to meet the demands of the engine, at idle position, fuel is bypassed back to the tank while when throttle is applied, vacuum is suppressed so that less fuel is returned ensuring enough pressure is achieved. In the case of Ford Excursion, it has used different kinds of Fuel Pressure Regulators, which consists of pressure reducing regulator and back-pressure regulator. The primary distinction lies in their operation: pressure reducing regulators reduce the input pressure whilst the back pressure regulators keep a steady inlet pressure. Like most OEM regulators, they work very well under standard conditions however where people opt for larger injectors than stock or other high volume pumps, adjustable after market options would be ideal.
