  Q: How to replace the fuel pressure regulator on Buick Park Avenue?

  A:

  The first step when replacing the fuel pressure regulator involves both reducing fuel pressure and removing all dirt from the fuel pressure regulator retaining ring. The next step involves removing the vacuum hose from the pressure regulator before you take out the snap ring. You should utilize a shop towel to contain fuel drips while you twist the fuel pressure regulator to remove it from the fuel pressure regulator housing. Start by taking away the regulator O-ring small and then reduce the regulator filter screen followed by removing the regulator O-ring large and finally the regulator O-ring back up. The housing of the fuel pressure regulator should get covered to stop contaminants from entering. The installation procedure must exclude compressed air for tests or cleaning the fuel pressure regulator to prevent damage. Gasoline can be used for cleaning fuel pressure regulator filter screen but immersion of the fuel pressure regulator in solvent baths should be prevented. A new fuel pressure regulator installation does not require new O-rings unless the fuel pressure regulator itself is new. The O-rings need light engine oil lubrication. Fasten the regulator back up O-ring followed by the regulator O-ring large and regulator filter screen together with a new regulator O-ring small part before reinstalling the fuel pressure regulator into its housing. Connect the fuel pressure regulator snap ring along with its vacuum hose. Perform the leak check by operating the ignition for ten seconds at first followed by turn OFF and a second ON cycle to inspect for any fuel leakage. Fix the fuel injector sight shield as a part of the installation process.
