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.
Note: The following procedure should be adopted in order to install the fuel injection lines when the electronic unit injectors or the fuel manifold have not been removed. If the electronic unit injectors or the fuel manifold have been removed, refer to Disassembly and Assembly, "Electronic Unit Injector - Install" and Disassembly and Assembly, "Fuel Manifold - Install" for more information.

Remove the relevant plug from fuel manifold (24) and fuel injection pump (29).
Remove the caps from new fuel injection line (28).
Position fuel injection line (28) onto fuel injection pump (29) and fuel manifold (24). Loosely install nuts for the fuel injection line onto the fuel manifold and the fuel injection pump.
Use Tooling (B) to tighten the nuts on fuel injection line (23) to a torque of 25 N m (221 lb in). Note: Ensure that fuel injection lines do not contact any other engine component.
Remove the caps from the port of the electronic unit injector and from the appropriate port in fuel manifold (16).
Loosely connect the nuts at both ends of fuel injection line (12) to the electronic unit injector and to the appropriate port in fuel manifold (16). Ensure that the ends of the fuel injection line are correctly seated in the electronic unit injector and in the fuel manifold.
Repeat Step 5 through Step 6 in order to install the remaining fuel injection lines.
Position clamp (22) onto fuel injection lines (12) and install clamp bolt (20). Tighten the bolt to a torque of 10 N m (89 lb in). Note: Ensure that the rubber separator is correctly installed around the fuel injection lines. Ensure that fuel injection lines do not contact any other engine component.
Repeat Step 8 for the remaining fuel injection lines.
Use Tooling (B) to tighten the nuts on fuel injection line (12) to a torque of 25 N m (221 lb in).
