2000 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to service and repair the fuel pressure regulator on 2000 Buick Park Avenue?

  A: The fuel pressure regulator service and repair process requires using the Fuel Pressure Gauge (J 34730) to drain the fuel pressure before continuing. After cleaning the fuel pressure regulator retaining ring remove the vacuum hose from the component. Before detachment begin by removing the snap ring followed by lifting and twisting the fuel pressure regulator using a shop towel to contain any fuel spillage from the fuel pressure regulator housing. Start by removing the small O-ring from the regulator and then the filter screen followed by large and back up O-rings. Put a covering over the fuel pressure regulator housing before contamination can occur. To install the fuel regulator without a replacement part use fresh O-rings on the regulator which need slight engine oil lubrication. Place the regulator back up O-ring followed by the regulator O-ring large and then the regulator filter screen after installing the regulator O-ring small. You should place the fuel pressure regulator into the fuel pressure regulator housing and follow it by installing the snap ring and the vacuum hose to the fuel pressure regulator. The installation of the fuel injector sight shield should be completed last.
