2000 Cadillac Seville Fuel Pressure Regulator Parts and Q&A

• Q: How to service and repair the fuel pressure regulator using the Fuel Pressure Gauge (J 34730) on 2000 Cadillac Seville?

  A: Repairs and servicing of the Fuel Pressure Regulator demand the use of a fuel pressure gauge (J 34730). Start with depresurizing the fuel system. Wash the retaining ring of the Fuel Pressure Regulator and uncouple the vacuum hose from the pressure regulator. The retainer clip from the Fuel Pressure Regulator must be taken out first followed by lifting and twisting the pressure regulator to break its connection from the housing while using a shop towel to catch any fuel leaks. Everyone should remove the regulator seal lower o-ring followed by the regulator assembly filter and the regulator seal upper o-ring along with the regulator seal back up ring. Space a cloth piece over the Fuel Pressure Regulator housing to stop contamination from entering. A new o-ring should go on the regulator before installation alongside engine oil lubrication of the o-ring. Install the regulator seal lower o-ring followed by the regulator assembly filter then the regulator seal upper o-ring after which the regulator seal back up ring should be put in place. After installing the regulator back up ring and vacuum line connector the retainer clip will be reattached. After Battery Cable reconnection the technician needs to check for leaks through the fuel system by following ignition cycle procedures and visually inspect the fuel system. Put in the reserve seat cushion before attaching the fuel injector sight shield onto the engine block while torquing its nuts to 3 n.m (27 lb in).
