Remove the fuel injection lines. Refer to Disassembly and Assembly, "Fuel Injection Lines - Remove" for the correct procedure.
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 g06185357
Thoroughly clean the area around fuel manifold (7).
Disconnect harness assembly (2) from the electronic unit injector connection.
Disconnect the harness assembly from fuel pressure sensor (1).Note: The fuel pressure sensor is not serviceable. If the fuel pressure sensor is faulty, the fuel manifold assembly must be replaced.
Disconnect the harness assembly from electronic pressure limiting valve (3).Note: The electronic pressure limiting valve is not serviceable. If the electronic pressure limiting valve is faulty, the fuel manifold assembly must be replaced.
Remove banjo bolt (5) from plastic tube assembly connection (4). Use Tooling (A) to plug the plastic tube assembly Remove sealing washers (6) (not shown). Use Tooling (A) to plug fuel manifold (7).
Remove bolts (9) and position bracket (8) away from fuel manifold (7).
