OEM 2002 Buick Regal Fuel Pressure Regulator

2002 Buick Regal Parts Questions & Experts Answers

• Q: How to service the fuel pressure regulator on 2002 Buick Regal?

  A: The service operation for a Fuel Pressure Regulator requires two steps - removal of fuel pressure then careful handling of components due to potential fuel contamination while servicing. The Fuel Pressure Regulator retaining ring needs cleaning before removing the vacuum line from the pressure regulator. The first step is to eliminate the snap ring while employing a shop towel to contain any fuel leakage to extract the Fuel Pressure Regulator from its housing . Remove three o-rings composed of small, large and back up regulators from the Fuel Pressure Regulator housing while using protective covering to stop contamination. A new Fuel Pressure Regulator should not be used for installation unless replacing the o-rings so lubricate them with clean engine oil after installing new o-rings. Proceed by putting the Fuel Pressure Regulator into the housing while placing the back up o-ring then the large o-ring and the small o-ring one at a time. Fasten the snap ring while reattaching the vacuum line to its place. The fuel fill cap needs tightening before reattaching the negative Battery Cable. To inspect for fuel leaks after completion turn the ignition on for 2 seconds followed by turning it off for 10 seconds then check for leaks after turning the ignition on again. The last step includes mounting the fuel injector sight shield as the conclusion of your task.
