    Note


    • Do not remove the fuel pressure sensor from the fuel delivery pipe sub-assembly LH.

    • If the fuel pressure sensor is removed, replace a new fuel delivery pipe with sensor assembly LH.

  5. REMOVE FUEL PIPE PLUG SUB-ASSEMBLY


    1. Secure the fuel delivery pipe with sensor assembly LH in a vise between aluminum plates.

      Note

      Do not overtighten the vise.

    2. Remove the dust cap sub-assembly from the fuel pipe plug sub-assembly.
