NOTE:  Before you install the fuel joint pipe (A), loosen the high pressure fuel pump mounting bolts (B).

1. Lubricate the top of the new fuel joint pipe (C) and the threaded area (D) of the fuel rail and the high pressure fuel pump with polyethylene glycol of a new fuel joint pipe kit.

NOTE:  Do not reuse the fuel joint pipe.

2. Tighten the fuel joint pipe nuts (E) by hand until the end of the joint pipe is seated on the fuel rail or high pressure fuel pump

3. Set the fuel joint pipe bracket (F) to the cylinder head, and loosely install the bolt (G).

4. Tighten the high pressure fuel pump mounting bolts (A) to the specified torque.

5. Tighten the fuel joint pipe bracket mounting bolt (B) to the specified torque.

6. Tighten the fuel joint pipe nuts (C) to the specified torque in the numbered sequence shown.

NOTE:  A crowfoot-type special tool increases the torque applied by the torque wrench. Refer to Torque Specifications for details on how to recalculate the torque wrench setting.

7.Connect the quick-connect fitting (D).

1. Turn the vehicle to the ON mode, but do not start the engine. After the fuel pump runs for about 2 seconds, the fuel line will be pressurized. Repeat this two or three times, then check for fuel leakage.
