Caution: Refer to Fastener Caution in the Preface section.
- Start and hand tighten the remaining fuel rail bolts.
3.1. | Tighten the fuel rail bolts in sequence to
22 N·m (16 lb ft). |
3.2. | Tighten the fuel rail bolts in sequence a second time to
22 N·m (16 lb ft). |
- Install the fuel injector noise insulator.
- Connect the electrical harness to the fuel rail harness connection.
Note: The camshaft must be in the base circle position before the high pressure fuel pump is installed.
- Use the
EN-48896 alignment gage
(2) to ensure that the camshaft lobe is in the base circle position. At base circle the tool will be flush with the head (1).
- Lubricate the high pressure fuel pump cylinder head bore with 5W30 engine oil.
Note: Ensure that the high pressure fuel pump roller lifter is oriented properly, the camshaft is at base circle, and the number 1 piston is at top dead center (TDC) on the exhaust stroke. The distance from the mounting
flange surface to the camshaft at base circle should be 52 mm (2.05 in).
- Lubricate the high pressure fuel pump roller lifter with 5W30 engine oil and install into the cylinder head bore.
- Install a NEW high pressure fuel pump gasket.
- Install a NEW high pressure fuel pump O-ring.
Note: Ensure the plastic bolt retainers are installed in the high pressure fuel pump mounting holes before installing.
- Install the high pressure fuel pump.
- Start and hand-tighten the high pressure fuel pump bolts evenly and tighten to
15 N·m (11 lb ft).
- Install and hand-tighten both ends of the NEW high pressure fuel line.
Tighten the high pressure fuel line fitting nuts to
