2. Install new O-ring (22) to fuel injection pump assembly (10).

3. Install fuel injection pump assembly (10) to the front housing. Ensure that the timing mark on the fuel injection pump gear and the camshaft gear are aligned as shown in Illustration 2.

4. Install bolts (13), (14), (16), (17), (18), (19), and (20). Install nut (15). Tighten nut (15) and bolts (13), (14), (16), (17), (18), and (19) to a torque of 10 N·m (88 lb in).

5. Install new fuel line (7) and tighten nuts (6) and (8) to a torque of 23 N·m (204 lb in).

   Note: If the high-pressure fuel line clamp was repositioned during disassembly, return the clamp to the original position.

6. Install banjo bolt (9) with new sealing washer (not shown) and tighten the bolt to a torque of 13 N·m (115. lb in).

7. Connect the fuel hose assembly to fuel inlet (21).

8. Reconnect the harness assembly to fuel temperature sensor (12) and fuel solenoid (11).

9. If necessary, replace O ring seal (4). Install O ring seal (4) into cover (5).

10. Install plate (3) and clip (2) complete with harness. Install bolts (1) and tighten to a torque of 26 N·m (230 lb in).

11. Install the fuel filter base, refer to Disassembly and Assembly, "Fuel Filter Base - Remove and Install" for the correct procedure.

12. Turn the fuel supply to the ON position. Turn the battery disconnect switch to the ON position.

13. Prime the fuel system, refer to Operation and Maintenance Manual, "Fuel system - Prime".

14. After replacement of the fuel injection pump, the fuel injection pump must be calibrated in order to prevent damage to the fuel system. Use the electronic service tool to perform "Fuel Pump Learn".
