Information:
Install Tooling (E). Tighten Tooling (E) to a torque of 9 1 N m (80 9 lb in).Note: The pump will not function while Tooling (E) is installed. Running the fuel injection pump with the tooling installed will result in pump damage and system contamination.

Service replacement pump
Note: Service replacement pump is shipped pinned with warning tag (Z) installed under pinch bolt (E).

Illustration 13 g02029098
Install bolts (8).
Connect tube assembly (9) and connect both hose assemblies (10) and (11).
Illustration 14 g02025176Note: During installation, make sure that the fuel line caps remain in position until the fuel line is positioned near the corresponding ports in order 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 in order 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).
