Using Tooling (A) and a 3/4" ratchet, rotate the crankshaft until the timing mark on the fuel pump is visible through the inspection hole. Install Tooling (B) and tighten to a torque of 9 1 N m (80 9 lb in).Note: Mark the damper in relation to the front timing cover as a visual reference to ensure that the crankshaft has not moved while the fuel injection pump is removed.Note: The pump will not function while Tooling (B) is installed. Running the fuel injection pump with the tooling installed will result in pump damage and system contamination.
Illustration 3 g02025176Note: For installation purposes, mark and note the orientation of each harness assembly (3).
Disconnect harness assemblies (3).
Remove nut (5) and remove the clamp assembly. Discard the clamp assembly.
Loosen nuts (4) and (7). Remove the fuel line and discard the fuel line.
Disconnect hose assembly (6).

Illustration 6 g02025262
Remove bolts (13) and remove fuel pump (14).Installation Procedure
Note: Check the O-ring seals, the gaskets, and the seals for wear or for damage. Replace the components, if necessary.

Connect tube assembly (12).
Illustration 9 g02029098
Install bolts (8).
Connect tube assembly (9) and connect both hose assemblies (10) and (11).
Illustration 10 g02025176Note: During installation, make sure that the fuel line caps remain in position until the fuel line is positioned near the corresponding ports to prevent contamination. Ensure that the areas around the rail and fuel lines are thoroughly clean before continuing this procedure. If any parts are worn or damaged, use new parts for replacement. Cleanliness is an important factor. Ensure that no debris gets introduced into the fuel system during the installation procedure. If any parts are worn or damaged, use new parts for replacement.
Connect harness assemblies (3).
Install a new fuel line. Hand tighten nuts (4) and (7).
Position the clamp assembly and install nut (5). Hand tighten the nut. Failure to place the grommet correctly on the fuel line could result in a failed fuel line.Note: Ensure that the fuel lines are centered in the nuts prior to tightening. Do not use excessive force or bending to assemble the fuel lines.
Tighten nut (4) at the fuel rail to a torque of 27 3 N m (239 27 lb in).
Tighten nut (7) to a torque of 27 3 N m (239 27 lb in).
Tighten nut (5) to a torque of 12 3 N m (105 27 lb in).
