  Q: How to replace the fuel pressure regulator on Chevrolet Classic?

  A:

  A proper replacement of the Fuel Pressure Regulator starts with reducing fuel system pressure. You should remove the vacuum pipe from the Fuel Pressure Regulator then use a shop towel to absorb possible fuel leakage. The replacement begins with removing retaining bolts and the Fuel Pressure Regulator after clearing away any seal material remaining on the Fuel Rail . When installing the o-rings place engine oil on them before assembly. The small o-ring needs to be installed within the Fuel Rail then the larger o-ring should be positioned after it. Instert the Fuel Pressure Regulator into its place while avoiding o-ring disturbance before tightening its retaining bolts to 5 n.m (44 lb in). Reinstall the vacuum pipe together with the negative Battery Cable. The leak inspection process begins with turning on the ignition for two seconds when the engine is off followed by turning the ignition off for ten seconds then repeating the ignition on to check for fuel leakages. The storage container should receive the shop towel to finish the procedure.
