Removal

WARNING: Before beginning any service procedure in this section, refer to Safety Warnings in Section 100-00. Failure to follow this instruction may result in serious personal injury.

WARNING: Clean all fuel residue from the engine compartment. If not removed, fuel residue may ignite when the engine is returned to operation. Failure to follow this instruction may result in serious personal injury.

WARNING: Do not work on the fuel system until the pressure has been released and the engine has cooled. Fuel in the high-pressure fuel system is hot and under very high pressure. High-pressure fuel may cause cuts and contact with hot fuel may cause burns. Failure to follow these instructions may result in serious personal injury.

NOTE: A clean working environment is essential to prevent dirt or foreign material contamination.

  1. Release the fuel system pressure, refer to Section 310-00.
  1. Disconnect the battery ground cable, refer to Section 414-01.
  1. Remove the intake manifold, refer to Section 303-01C.
  1. NOTE: When removing or installing the fuel injection pump noise insulator, spreading the openings will reduce the risk of damage.
