Chevrolet Avalanche 2500 Fuel Pressure Regulator Parts Questions & Experts Answers
Q: How to service and repair the fuel pressure regulator on Chevrolet Avalanche 2500?
A: A service or repair operation on the Fuel Pressure Regulator requires first draining the fuel system pressure from the system. You should disconnect the Fuel Pressure Regulator vacuum line before cleaning the surrounding retainer area as well as the regulator retainer itself from any dirt. You need to first remove the Fuel Pressure Regulator retainer before pulling out the Fuel Pressure Regulator from the Fuel Pressure Regulator housing. Before installing the parts you should position the back up ring onto the Fuel Pressure Regulator. Next, use new large o-ring and regulator filter. Before installation of new Fuel Pressure Regulator elements you must apply clean engine oil to both the large and small o-rings that are set on the Fuel Pressure Regulator. Insert the Fuel Pressure Regulator into the housing located on the Fuel Rail while installing a brand new Fuel Pressure Regulator retainer. Finish the process by linking back the Fuel Pressure Regulator vacuum line with the negative Battery Cable before tightening the fuel filler cap. At first, turn on the ignition when the engine is off for 2 seconds followed by waiting 10 seconds while turning off the ignition before restarting the ignition with the engine off for leak inspections. The last installation step should be the fuel injector sight shield.
