  Q: How to replace the fuel pressure regulator in a with VIN K on Buick LeSabre?

  A:

  A technician faces two steps to replace the fuel pressure regulator for vehicle VIN K by first reducing fuel pressure while cleaning the retaining ring. First remove the vacuum hose connected to the pressure regulator before you detach the retaining snap ring. The fuel pressure regulator requires lifting and twisting movements with a shop towel underneath to disconnect it from the fuel pressure regulator housing . The subsequent steps involve taking out the regulator O-ring small along with the regulator filter screen and regulator O-ring large and regulator O-ring back up. Seal the fuel pressure regulator housing since it must stay protected from contamination. The technician should install new O-rings onto fuel pressure regulator components when a new regulator is not used. These parts should receive a light dose of clean engine oil before installation. The installation of the fuel pressure regulator requires you to place the regulator back up O-ring followed by regulator O-ring large after that apply the regulator filter screen and finalize with regulator O-ring small before returning the fuel pressure regulator into the fuel pressure regulator housing . Lock the installation by using the snap ring then restore the vacuum hose connection to the fuel pressure regulator. Proofing fuel leaks requires you to turn ON the ignition for 10 seconds followed by turning it OFF before repeating in 10 seconds to examine leaks. Place the fuel injector sight shield during conclusion of the installation process.

  Q: How to service the fuel pressure regulator on Buick LeSabre?

  A:

  Service of the fuel pressure regulator begins by lowering the fuel system pressure. Before removing the vacuum hose from the pressure regulator you should clean the dirt from its retaining ring. Use a shop towel to prevent fuel leakage as you lift and twist the fuel pressure regulator from its housing by removing the snap ring. Starting with the small regulator O-ring, remove each of these components from the regulator housing along with its regulator filter screen and large regulator O-ring and back up regulator O-ring. A protective wrapping should cover the fuel pressure regulator housing to stop contamination during this procedure. Use compressed air on the fuel pressure regulator only during installation because it can create damage to the components. Gasoline should be used to clean the fuel pressure regulator filter screen but the fuel pressure regulator should not go into solvent bath for cleaning. New O-rings should be installed on the fuel pressure regulator regardless of new part installation and require light engine oil application as lubrication. Organize the installation process by adding the back up regulator O-ring as a baseline followed by the large regulator O-ring and after that install the regulator filter screen followed by the small regulator O-ring. The next step includes inserting the fuel pressure regulator into the fuel pressure regulator housing followed by using the snap ring to hold it in place and reattaching the vacuum hose to the fuel pressure regulator until you complete by fixing the fuel injector sight shield.
