Failure to follow this instruction may result in dirt entering the fuel injection system.

CAUTION: This procedure must be performed before attempting to start the engine after removing or replacing any part of the fuel system that has penetrated the fuel line. Failure to follow this instruction may result in damage to the fuel pump.

1. This procedure is required when removing, disconnecting, or replacing any of the following fuel system parts: fuel tank, fuel lines, fuel filter element, fuel coolers, fuel pump, or fuel rail pressure sensor.

2. Remove the engine cover. Engine cover - 2.7L Diesel (12.30.50)

3. Install the special tool on the fuel manifold schrader valve. Remove the dust cap from the Schrader valve.

4. Place a container to catch spilled fuel. Open the valve on the special tool.

5. Turn the ignition key to the ON position for 25 seconds. In this case, you should hear noise from the operation of the fuel pump in the tank.

6. Repeat this procedure until clean fuel comes out of the special tool without air bubbles. Without turning off the pump, turn off the valve on the special tool to prevent air from entering the system.

7. Remove the special tool from the Schrader valve. Put the dust cap on the schrader valve.
