• Q: How to service and repair the fuel pressure regulator on 2002 Buick Rendezvous?

  A: A technician should begin the Fuel Pressure Regulator service by draining fuel system pressure. Begin by detaching the Fuel Pressure Regulator vacuum line followed by removal of its retaining screw. Before removing the Fuel Pressure Regulator from the Fuel Rail you need to use a shop towel to prevent fuel spillage after lifting and twisting the regulator. Dismount the retainer along with spacer bracket from the rail before separating the Fuel Pressure Regulator from the engine fuel return pipe and throwing away the inlet o-ring. Using the fuel return line before installation will prevent regulator rotation that could damage the retainer and spacer bracket while avoiding fuel leakage. Test and cleaning of the Fuel Pressure Regulator should never use compressed air during operation and screening of the filter can be cleaned using gasoline but the regulator must stay out of solvent baths. The Fuel Pressure Regulator requires new installation if the filter screen shows contamination. The new inlet o-ring requires cleaning engine oil for lubrication before putting it onto the regulator inlet. Affix the fuel return pipe to the regulator after that attach the new retainer and spacer bracket to the slot available on the Fuel Rail. Install the pressure regulator onto the Fuel Rail while ensuring tight torque of 17 n.m (13 lb ft) on the engine fuel return pipe nut. Pursue heating up the Fuel Pressure Regulator vacuum line before proceeding to tighten its attaching screw up to 8.5 n.m (76 lb in). A proper fit can be verified when you pull on the regulator as its components connect to the Fuel Rail slots. After following the ignition turn on for 2 seconds and turn off for 10 seconds, check for any fuel leaks by performing an ignition on test.
