Fuel Pressure Gage Installation and Removal

FUEL PRESSURE GAGE INSTALLATION AND REMOVAL

TOOLS REQUIRED
- J 34730-1A Fuel Pressure Gage
- J 34730-75Fuel Pressure Gage Adapter

INSTALLATION PROCEDURE
1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure.
2. Disconnect the negative battery cable.

CAUTION: Refer to Battery Disconnect Caution in Service Precautions.




3. Disconnect the fuel supply hose (2) from the fuel rail supply pipe (5). Use a shop towel in order to catch any remaining fuel that may leak.
4. Connect the hose end of the J 34730-75 (3) to fuel rail supply pipe (5).
5. Connect the fuel supply hose (2) to the J 34730-75 (3).
6. Secure both connections with the hose clamps.
7. Install the J 34730-1A (4) to the J 41041 (3).
8. Connect the negative battery cable.

NOTE: Refer to Fastener Notice in Service Precautions.

9. Turn ON the ignition in order to pressurize the fuel system.
10. Turn OFF the ignition.
11. Check for any fuel leaks and repair as necessary.
12. Start the engine.
13. Idle the engine at the normal operating temperature.
14. Verify the fuel pressure as follows:
- 210-260 kPa (30-37 psi) with the engine idling.
- 270-310 kPa (39-45 psi) when the engine is not running, the ignition switch is On, and the fuel pump running.
- The fuel pressure should hold at or more than 200 kPa (29 psi) within 1 minute of the engine not running while the ignition switch is Off and the fuel pump is not running.
15. If the fuel pressure is not within the specifications, refer to Fuel System Diagnosis.

REMOVAL PROCEDURE
1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure.
