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

  A:

  The first step for Fuel Pressure Regulator service includes pressure relief and fuel system component cleanliness during handling. Wash all debris from the retaining ring of the Fuel Pressure Regulator before you take off its vacuum line. The next step requires removal of the snap ring and the use of a shop towel to contain any fuel drippings during the process of detaching the Fuel Pressure Regulator from its housing by lifting and twisting it. Insert a cover across the Fuel Pressure Regulator housing after removing the regulator o-ring small, regulator o-ring large, and regulator o-ring back up to maintain contaminant prevention. The first step for installation requires new o-rings on the Fuel Pressure Regulator before a thin coating of clean engine oil is applied to them. Place the Fuel Pressure Regulator inside the Fuel Pressure Regulator housing while securing it with the snap ring after installing the regulator back up o-ring followed by the regulator o-ring large before finalizing with the regulator o-ring small. Return the vacuum line to the Fuel Pressure Regulator then fasten the fuel fill cap while connecting the negative Battery Cable. A leak inspection requires turning on the ignition for two seconds before turning it off for ten seconds followed by another ignition on cycle to detect fuel leaks. The last step requires installation of the fuel injector sight shield.

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

  A:

  The first step to replace the fuel pressure regulator requires users to drain the pressure while also keeping all fuel system components clean. Wipe the fuel pressure regulator retaining ring to remove dirt before taking off the vacuum line from the pressure regulator. Extract the snap ring before using a shop towel to collect spilled fuel during the removal procedure of the fuel pressure regulator from its housing. Remove the small O-ring attached to the regulator as well as the filter screen and large O-ring and back up O-ring from the regulator unit. The housing of the fuel pressure regulator needs coverage to avoid getting contaminated. Installing the fuel pressure regulator requires avoidance of compressed air usage since it can result in regulator damage. Use gasoline to clean the filter screen of the fuel pressure regulator yet refrain from placing the regulator into a solvent solution. For installation attach new O-rings to the fuel pressure regulator then apply light engine oil on the O-rings and proceed with installation beginning with the regulator O-ring back up followed by the regulator large O-ring then regulator filter screen and regulator small O-ring. Affix the fuel pressure regulator into the fuel pressure regulator housing by using the snap ring for installation. Connect both vacuum lines from the fuel pressure regulator to the fuel system and restore the negative battery power source. A fuel leak check should be conducted by activating the ignition for 2 seconds followed by turning it off for 10 seconds before a second ignition turn-on for leak detection. Put on the fuel injection sight shield as the last step of the installation.
