Removal Procedure
NOTICE |
---|
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. |
- Remove tube assemblies (1), (2) and (3) from the engine.
Illustration 1 | g01613075 |
Typical example |
- Remove the old secondary fuel filter canister. Refer to Operation and Maintenance Manual, "Fuel System Secondary Filter - Replace" for the correct procedure.
- Remove the existing secondary fuel filter base. Refer to Disassembly and Assembly, "Fuel Filter Base - Remove and Install (Secondary Fuel Filter)" for the correct procedure.
- Remove the secondary fuel filter base mounting bracket from the inlet manifold. Discard the mounting bracket.
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. |
- Install two setscrews (4) to new mounting bracket (2). Install the mounting bracket assembly to the inlet manifold. Tighten the setscrews (4) to a torque of 22 N·m (16 lb ft).
Illustration 2 | g01613193 |
Typical example |
- Install two setscrews (3) to new secondary fuel filter assembly (1) .
Note: The new secondary fuel filter base will have a identification mark on the top of the secondary fuel filter base (A). The identification mark is a hole that has a depth of 3 mm (0.1181 inch).
- Install new secondary fuel filter assembly (1) to new mounting bracket (2). Tighten setscrews (3) to a torque of 55 N·m (41 lb ft).
- Install tube assembly (5) .
Illustration 3 | g01613217 |
Typical example |
- Install the steel section of the injector leak off pipe assembly (6) to the pressure relief valve.
- Install the nut to the end of the injector leak off pipe. Install the olive to the end of the injector leak off pipe. Push the end of the injector leak off pipe into the connection. Tighten the nut finger tight.
- Ensure that the connection does not move. Using a suitable tool, tighten the nut to a torque of 26 N·m (19 lb ft) for a steel connection or 21 N·m (15 lb ft) for a brass connection.
- Press tube assembly (5) into the correct clip.
- Install tube assembly (7) to the inlet connection of the fuel injection pump and the outlet connection of the secondary fuel filter base. Tighten the nuts to a torque of 26 N·m (19 lb ft) for a steel connection or 21 N·m (15 lb ft) for a brass connection.
Note: If a compression fitting has been assembled to a connection, tighten the nut until a sharp rise in torque is felt, then tighten the nut an additional one third of a turn.
Illustration 4 | g01613219 |
Typical example |
- Install tube assembly (8). Install one end of tube assembly (8) to the ECM connection and install the other end of tube assembly (8) to the inlet connection of the secondary fuel filter base. Install two pipe clips. Clip tube assembly (8) onto the bracket.
Illustration 5 | g01613220 |
Typical example |
- Prime the fuel system. Refer to Operation and Maintenance Manual, "Fuel System Prime".
- Run the engine. Check the fuel system for leaks.
