Install the intake manifold studs in the manifold face and tighten to 15-Y (11-lb-ft).

Install the intake manifold-(1). Start and hand tighten the intake manifold boltsand nuts.

Tighten the bolts and nuts in sequence to 25-Y (18-lb-ft).

Install the intake manifold insulator-(2).Install the insulator bolt and tighten to 10-Y (89-lb-in).Install the fuel rail harness connector bracket-(1) to the intake manifold. Tightenthe bracket bolt to 10-Y (89-lb-in).

Note:The camshaft must be in the base circle position before the high pressure fuel pumpis installed.

Use the EN-48896 alignment gauge-(2) to ensure that the camshaft lobe is in the base circle position. At base circleposition, 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 camshaftis at base circle, and the number-1 piston is at top dead center-(TDC) on the exhauststroke. The distance from the mounting flange surface to the camshaft at base circleshould be 52-mm (2.05-in).

Lubricate the high pressure fuel pump roller lifter-(1) with 5W30 engine oil and installinto the cylinder head bore.Install a NEW fuel pump housing O-ring-(2) and gasket-(3).

Note:Ensure the plastic bolt retainers are installed in the high pressure fuel pump mountingholes before installing.
