2002 GMC Safari Fuel Pressure Regulator Parts Questions & Experts Answers

• Q: How to service and repair the fuel pressure regulator on 2002 GMC Safari?

  A: A proper start for servicing or repairing the Fuel Pressure Regulator requires following the fuel pressure relief procedure in computers and controls systems to drain fuel system pressure. Begin by removing the upper intake manifold assembly after which you should detach the Fuel Pressure Regulator retainer clip. The Fuel Pressure Regulator can be separated from the housing by twisting it outward while using a shop towel to absorb any fuel that leaks. Remove the regulator seal lower o-ring, the regulator assembly filter, the regulator seal upper o-ring and the regulator seal back up ring from the regulator assembly then discard the o-rings. The filter screen inside the Fuel Pressure Regulator needs examination for contaminants before installing it again only if the regulator requires replacement. The installer should apply clean engine oil to the new o-rings before putting the regulator seal back up ring followed by the regulator seal upper o-ring then the regulator assembly filter before finishing with the regulator seal lower o-ring. Install the regulator after directing its vacuum tube downwards into the retainer clip before you install both the retainer clip and upper manifold assembly. Start the ignition with engine off before turning it off again after 10 seconds to look for fuel leaks while performing the negative Battery Cable reconnection. Finally, install the engine cover.
