2000 Buick Regal Fuel Pressure Regulator Parts and Q&A

• Q: How should you service the fuel pressure regulator while maintaining cleanliness on 2000 Buick Regal?

  A: When working on fuel system components users must keep everything clean before starting service on the Fuel Pressure Regulator. The first step should involve relieving the fuel pressure. The Fuel Pressure Regulator retaining ring needs cleaning of all visible dirt before you detach the vacuum line leading to the pressure regulator. The first step is to remove the retaining ring snap while using a shop towel to absorb fuel to lift and twist the Fuel Pressure Regulator before freeing it from the housing. You must remove the small regulator o-ring along with the large and back up regulator o-rings before placing a cover on the Fuel Pressure Regulator housing to stop contamination. Before reframing the Fuel Pressure Regulator you must replace its o-rings with new ones and apply clean engine oil for light lubrication. Place the Fuel Pressure Regulator inside the Fuel Pressure Regulator housing and fasten it with a snap ring. After that install the regulator o-ring small, the regulator o-ring large, and the regulator o-ring back up. Install the vacuum line to the Fuel Pressure Regulator, tighten the fuel fill cap then reconnect the negative Battery Cable. A leak inspection process includes turning on the ignition for two seconds followed by ten seconds of ignition off time before reactivating the ignition to check for fuel leaks. Stand at the end of your installation by putting on the fuel injection sight shield.
