Removal

1. Remove the vertical EGR cooler. For additional information, refer to Emission Control Systems.

2. Remove the engine wiring harness bolt.

3. Disconnect the wiring harness retainer from the engine lifting bracket.

4. Disconnect the fuel temperature sensor electrical connector.

5. Disconnect the wiring harness retainer from the fuel filter module stud bolt.

6. NOTICE: Fuel injection equipment is manufactured to very precise tolerances and fine clearances. To prevent fuel system damage, it is essential that absolute cleanliness is observed when working with these components.

Remove the fuel filter module cover and, using a suitable suction device, remove the fuel from the fuel filter module.

- Install the fuel filter module cover when finished.
- Tighten to 27 Nm (20 lb-ft).

7. Loosen the clamps and remove the Charge Air Cooler (CAC) tube flex coupling.

8. NOTICE: Fuel injection equipment is manufactured to very precise tolerances and fine clearances. To prevent fuel system damage, it is essential that absolute cleanliness is observed when working with these components. Always install Fuel System Caps on any open orifices or tubes.

Remove the 3 banjo bolts and 6 sealing washers, and detach the fuel tubes from the fuel filter module.

- Plug or cap the openings and tubes as needed.

- Discard the sealing washers.

9. Remove the 2 fuel filter module bolts and stud bolt.

10. NOTICE: Fuel injection equipment is manufactured to very precise tolerances and fine clearances. To prevent fuel system damage, it is essential that absolute cleanliness is observed when working with these components. Always install Fuel System Caps on any open orifices or tubes.

Position the fuel filter module to access and, using a commercially available disconnect tool, disconnect the fuel injection pump supply tube. Remove the fuel filter module.

- Plug or cap the opening and tube as needed.

Installation

1. Connect the fuel injection pump supply tube and position the fuel filter module.

2. Install the 2 fuel filter module bolts and stud bolt.
