Contact with high pressure fuel may cause fluid penetration and burn hazards. High pressure fuel spray may cause a fire hazard. Failure to follow these inspection, maintenance and service instructions may cause personal injury or death.
Ensure that all adjustments and repairs that are carried out to the fuel system are performed by authorized personnel that have the correct training.Before beginning ANY work on the fuel system, refer to Operation and Maintenance Manual, "General Hazard Information and High Pressure Fuel Lines" for safety information. Refer to System Operation, Testing and Adjusting, "Cleanliness of Fuel System Components" for detailed information on the standards of cleanliness that must be observed during ALL work on the fuel system.
Illustration 1 g02178677
Thoroughly clean the area around fuel manifold (4).
Disconnect harness assembly (6) from fuel pressure sensor (5).
Disconnect plastic tube assembly (1) from the fuel pressure relief valve on fuel manifold (4). Immediately cap the open port in fuel manifold (4) with a new cap. Immediately plug the open end of plastic tube assembly (1) with a new plug.
Remove bolt (2) and bolts (3). Remove fuel injection line support bracket (7).
Remove fuel manifold (4) from the cylinder head. Installation Procedure
Ensure that all adjustments and repairs that are carried out to the fuel system are performed by authorized personnel that have the correct training.Before beginning ANY work on the fuel system, refer to Operation and Maintenance Manual, "General Hazard Information and High Pressure Fuel Lines" for safety information. Refer to System Operation, Testing and Adjusting, "Cleanliness of Fuel System Components" for detailed information on the standards of cleanliness that must be observed during ALL work on the fuel system.
Ensure that all ports on the fuel manifold are capped. Ensure that the fuel manifold is externally clean and free from damage. Note: Do not install a fuel manifold that has not been capped. All caps must be left in place until the fuel injection lines or the fuel pressure relief valve are installed.
