• Q: How to replace the fuel pressure regulator on 2005 Chevrolet Classic?

  A: The first step to replace the Fuel Pressure Regulator requires relief of the fuel system pressure. The valve for vacuum pipe from the pressure regulator needs to be separated before setting a shop towel beneath it to absorb fuel leakage. Empty all retaining bolts before removing the Fuel Pressure Regulator while cleaning away any seal or seal material present on the Fuel Rail . Start by installing the small o-ring on the Fuel Rail and apply clean engine oil to it before its placement. The installation of the Fuel Pressure Regulator requires inserting the large o-ring into the Fuel Rail followed by gentle placement of the Fuel Pressure Regulator without disturbing its installed o-rings. Fasten the Fuel Pressure Regulator in position using its retaining bolts while keeping them tightened to 5 n.m (44 lb in). You should finish the installation by connecting the Fuel Pressure Regulator to its vacuum pipe and negative Battery Cable. Turn on ignition and turn off all power following two seconds on to perform a fuel leak inspection. Put the shop towel into an appropriate storage unit for keeping it.
