  • Q:

    Can you confirm if I order this that the part you send me will be the same as pic 1 with an adjustment screw ??? I have heard that Delphi changed to a non adjustable type but foolishly kept the very same part number. I do NOT want to order, and then when it arrives find out it is the non adjustable type and have to return it. Please let me know. Thanks!

      I'm happy to help, BC! This Delphi Fuel Injection Pressure Regulator (Part No. FP10021) has had no change in design. The item will contain the screw. The screw is used for final calibration and the pressure change the the screw will affect is not field-measureable.

      The fuel pressure regulator has a set pressure and is not adjustable and is designed to hold a specific pressure. The distance that the top half of the regulator is “crushed down” during the assembly process establishes the pressure set point.

    Where is the fuel pressur regulator located on a 03 Cadillac Escalade EXT 6.0 engine AWD

      The fuel pressure regulator should be mounted in the fuel rail, that way, the extra fuel exiting the fuel rail through the fuel pressure regulator will enter the fuel return line and it can travel back to the fuel tank.
