• Q: How to service the fuel pressure regulator on 2002 Cadillac Eldorado?

  A: One must begin Fuel Pressure Regulator service by first reducing fuel pressure and inspecting whether solid matter exists on the Fuel Pressure Regulator. The first step involves releasing fuel pressure along with cleaning of the Fuel Pressure Regulator. After that disconnect the vacuum line connected to the Fuel Pressure Regulator. The removal of the clip holding the regulator in place should occur next. The lift-twist motion of the Fuel Pressure Regulator against the Fuel Rail frees the Fuel Pressure Regulator while fuel spills are contained with a shop towel. Service the Fuel Pressure Regulator by eliminating the regulator seal lower o-ring as well as the regulator assembly filter and the regulator seal upper o-ring and regulator seal back up ring. The housing of the Fuel Pressure Regulator needs protection from contaminants that could enter the fuel system during this procedure. Before installing the Fuel Pressure Regulator you should place new o-rings on its unit and lightly oil them using clean engine oil. The Fuel Pressure Regulator needs installation with the back up ring first followed by the upper o-ring and filter and lower o-ring before fastening it with the retainer clip and vacuum line reconnection. Turn the ignition on for two seconds before turning it off for ten seconds to check for fuel leaks when inspecting the connection between the negative Battery Cable. Connect the sight shield for fuel injectors as the last step.
