2004 Chevrolet Monte Carlo Fuel Pressure Regulator Parts Questions & Experts Answers

• Q: How to replace the fuel pressure regulator on 2004 Chevrolet Monte Carlo?

  A: The procedure to replace a Fuel Pressure Regulator starts with emptying fuel system pressure. First disconnect the Fuel Pressure Regulator vacuum line before uninstalling its fuel return pipe together with the Fuel Pressure Regulator screw. The shop towel will catch flying fuel and the Fuel Pressure Regulator removal requires a lifting motion along with a twisting motion to separate it from the Fuel Rail. The procedure requires discarding both the Fuel Rail retainer and spacer bracket together with the inlet and return pipe o-rings of the Fuel Pressure Regulator. Check the filter screen for any contamination because replacement of the Fuel Pressure Regulator will be required. Clean engine oil should be used during Fuel Pressure Regulator inlet and fuel return pipe o-ring installation before placing them into position. You should attach the fuel return pipe to the Fuel Pressure Regulator after installing a fresh retainer along with spacer bracket at the Fuel Rail slot. Fasten the pressure regulator to the Fuel Rail and tighten the engine fuel return pipe nut to 17 n.m (13 lb ft). Secure the Fuel Pressure Regulator screw with torque set to 8.5 n.m (75 lb in). Check that the retainer together with the spacer bracket fit in the Fuel Rail slots by applying regulator force to ensure proper seating. The installation process requires connection of the Fuel Pressure Regulator vacuum line and negative Battery Cable. To verify the absence of fuel leaks you should switch the ignition to on for two seconds followed by a period of ten seconds off before another two-second ignition on while examining for fuel leaks.
