Tools Required

1. Relieve the fuel pressure. Refer to Fuel Pressure Relief .



2. Disconnect the fuel feed hose (2) from the chassis fuel feed pipe. Use a shop towel in order to catch any remaining fuel that may leak.



3. Install the J 34730-75 fuel rail adapter (1) to the chassis fuel feed pipe.
4. Connect the fuel feed hose (2) to the J 34730-75 fuel rail adapter (1), and secure the hose with the hose clamp.
5. Securely connect J 34730-1A the fuel pressure gauge (3) to J 34730-75 the fuel rail adapter (1).
6. Connect the negative battery cable.
7. Start the engine.
8. Idle the engine at normal operating temperature.
9. Use the following procedure in order to check the fuel pressure:

•	200-240 kPa (28.5-34 psi) with the engine idling.

•	270-310 kPa (38.5-44 psi) with the engine off and the ignition switch on.

•	The fuel pressure should remain at least 200 kPa (28.5 psi) within 1 minute of key-off and the ignition switch on.

10. If the fuel pressure is not within the specification, refer to Fuel System Diagnosis .

1. Relieve the fuel pressure. Refer to the Fuel Pressure Relief .



2. Remove theJ 34730-1A fuel pressure gauge (3) and the J 34730-75 fuel rail adapter (1) from the fuel feed hose and from the pipe. Use a shop towel in order to catch any remaining fuel that may leak.
3. Connect the fuel feed hose to the chassis fuel feed pipe, and secure the hose with a clamp.
4. Connect the negative battery cable.
5. Turn ON the ignition in order to pressurize the fuel system.
6. Turn OFF the ignition.
7. Check for any fuel leaks.
