Removal and Installation: Installation

Fuel Pump Drain Line: 

• Installation is in the reverse order of removal.

Fuel Pressure Relief Valve Drain Line 

1. Align the fuel pressure relief valve drain line (2) on the fuel rail [LH (1)] and install the banjo bolt (A) and new washers (B).

   CAUTION: Do not reuse the washers.

   Bolt (A)

   : 18 N.m (1.8 kg-m, 13 ft-lb)

2. Installation is in the reverse order of removal.
   NOTE: Operate the engine and check for leaks.

Injector Drain Line 

1. Lubricate the o-ring with clean diesel fuel.

2. Position the drain line (2) as previously routed.
   CAUTION: Do not reuse the O-ring (1).
3. Install the clips (A) securing the injector drain line (1). Three clips secure the injector drain line to the high-pressure rail to rail high-pressure fuel line and two clips secure the injector drain line to the rocker lever cover (LH).

4. The injector drain line (1) must be routed on the front side of the rail to rail high-pressure fuel line (2). (The Stage 2 filter is omitted for clarity.)

5. The constant pressure valve (3) should be flush with locating tab (4) on the rocker lever cover.
   NOTE:

   • Be sure that other components are not restricting the injector drain line.
   • Be sure the injector drain line is not twisted in the area of the constant pressure valve. This can cause a restriction in the line, resulting in poor performance.
   • The routing of the injector drain line is crucial to prevent other engine components from pinching the fuel return line.
6. Be sure the injector drain line quick disconnect connector is in the release position (the button is up).

   Press only on the connector tabs to seat the drain line onto the injector drain port. An audible snap sound will be heard when the connector is seated.

   When the connector snaps into place, press the center button to secure the connector.

7. Installation of remaining components is in the reverse order of removal.
   NOTE: Operate the engine and check for leaks.
