Cadillac Escalade Fuel Pressure Regulator Parts Questions & Experts Answers
Q: How to service and repair the fuel pressure regulator on Cadillac Escalade?
A: The first step of Fuel Pressure Regulator maintenance requires users to take off the engine sight shield then reduce fuel system pressure. Unplug the vacuum line of the Fuel Pressure Regulator and remove all dirt from the Fuel Pressure Regulator retainer area and its adjacent surroundings. Take out the Fuel Pressure Regulator retainer first and put it on the workbench followed by removal of the Fuel Pressure Regulator itself. The maintenance process demands the complete removal of back up ring as well as regulator seal o-ring together with regulator filter and regulator seal o-ring from the fuel rail system. Select the correct new Fuel Pressure Regulator retainer that includes tabs for the straight vacuum port retainers but the angle vacuum port retainer requires no tabs between installation steps. To install the back up ring along with the regulator seal o-ring , regulator filter and regulator seal o-ring onto the Fuel Pressure Regulator, lubricate all o-rings (11, 13) with clean engine oil before inserting the Fuel Pressure Regulator. Reinstallation of the Fuel Pressure Regulator requires both brand-new o-rings and a new retaining clip. The next step includes mounting the new Fuel Pressure Regulator retainer and refitting the Fuel Pressure Regulator vacuum hose before securing the fuel filler cap. To perform a leak inspection you must start the ignition system with the engine inactive for 2 seconds followed by engine shutdown for 10 seconds before repetition of the first step without engine activity. Investigate for fuel leakage at this point. The final step includes replacing the engine sight shield.
