Installation Procedure
- Use the EN 48896 alignment gauge (2) to ensure that the camshaft lobe is in the base circle position. At base circle position, the tool will be flush with the head (1).
- Lubricate the high pressure fuel pump cylinder head bore with 5W30 engine oil.
- Lubricate the high pressure fuel pump roller lifter with clean engine oil and install into the cylinder head bore.
- Install a NEW high pressure fuel pressure fuel pump gasket (4).
- Install a NEW high pressure fuel pump O-ring (5).
- Install the valve lifter follower (3).
- Install the high pressure fuel pump (2).
- Start and hand-tighten the NEW high pressure fuel pump bolts (1) evenly.
- Tighten the fuel pump bolts (1) a first pass in sequence to 15 N.m (11 lb ft).
- Tighten the fuel pump bolts (1) a final pass of an additional 60 degrees.
- Install the NEW fuel feed intermediate pipe. Refer to Fuel Feed Intermediate Pipe Replacement (LF3) .
- Install the NEW fuel feed pipe and fuel feed pipe shield. Refer to Fuel Feed Pipe Replacement (At Tank AWD) Fuel Feed Pipe Replacement (LF3 At Engine) .
The camshaft must be in the base circle position before the high pressure fuel pump is installed.
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 locator tab on the fuel pump gasket should be positioned away from the engine block.
Lubricate the NEW O-ring seals with clean engine oil.
Ensure the plastic bolt retainers are installed in the high pressure fuel pump mounting holes before installing.
Refer to Fastener Caution .
Alternately hand-tighten the fuel pump bolts one turn at a time until the pump is fully seated. Trying to draw down the pump without even side-to-side tightening may result in pump plunger damage.
This vehicle is equipped with torque-to-yield or single use fasteners. Install a NEW torque-to-yield or single use fastener when installing this component. Failure to replace the torque-to-yield or single use fastener could cause damage to the vehicle or component.
