2004 Chevrolet Impala Fuel Pressure Regulator Parts Questions & Experts Answers

• Q: How to replace the fuel pressure regulator while maintaining cleanliness in the fuel system on 2004 Chevrolet Impala?

  A: All fuel system parts require cleanliness for replacement of the Fuel Pressure Regulator component. First, relieve the fuel pressure. Fuelperformance cleaning should be applied to the Fuel Pressure Regulator retaining ring after which you should detach the vacuum line from the regulator. First detach the snap ring and lift and twist the Fuel Pressure Regulator while using a shop towel to catch any fuel leakage from the Fuel Pressure Regulator housing . To prevent contamination of the Fuel Pressure Regulator housing place a covering over it after removing small regulator o-ring along with regulator o-rings 4,5. New o-rings should be placed onto the Fuel Pressure Regulator before installation and receiving a light coating of clean engine oil. Apply the regulator o-rings (4,5) and small regulator o-ring before placing the Fuel Pressure Regulator into the Fuel Pressure Regulator housing where it can be held by the snap ring. Attach the vacuum line to the Fuel Pressure Regulator and fasten the fuel fill cap followed by connecting the negative Battery Cable. The inspection for fuel leaks requires turning on the ignition for 2 seconds then turning it off for 10 seconds before a second on ignition check for any fuel leaks. You should install the fuel injector sight shield as your final step in the procedure.
