2000 Cadillac DeVille Fuel Pressure Regulator Parts Questions & Experts Answers

• Q: How to service and repair the fuel pressure regulator on 2000 Cadillac DeVille?

  A: The first step for Fuel Pressure Regulator service involves using the fuel pressure gauge j34730-1a for decompression of the fuel pressure system. Keep every area clean during the entire procedure while working with fuel system objects. First clean the Fuel Pressure Regulator retaining ring of dirt before removing the vacuum hose from the pressure regulator. Release the retainer clip from the Fuel Pressure Regulator before cautiously lifting and twisting the Fuel Pressure Regulator housing to separate it from the unit while containing any leaking fuel with a shop towel. Before proceeding start by removing the regulator seal lower o-ring and then the regulator assembly filter followed by the regulator seal upper o-ring until finally removing the regulator seal back up ring. Apply a covering over the Fuel Pressure Regulator housing to stop external contamination. Installing the Fuel Pressure Regulator requires new o-rings along with light engine oil lubrication if the regulator is not replaced by a new one. Begin inserting the items into the regulator assembly starting with the regulator seal back up ring followed by the regulator seal upper o-ring then the regulator assembly filter and concluding with the regulator seal lower o-ring . Reinstall the retainer clip onto the Fuel Pressure Regulator and the vacuum line section. The inspection for fuel system leaks starts when you turn on the Battery Cable followed by a two-second ignition on then ten-second ignition off period before turning it on again to check for any fuel system leaks. Fasten the engine steps by positioning the rear seat cushion and the intake manifold sight shield and tightening the intake manifold sight shield nuts to 3 n.m (27 lb in).
