Fuel Pressure Gauge Installation

Fuel Pressure Gauge Installation


REMOVAL PROCEDURE




1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure.
2. Disconnect the J 34730-1A fuel pressure gauge from the J 41041 fuel pressure gauge adapter. Use a shop towel in order to catch any remaining fuel that may leak.
3. Disconnect the J 41041 fuel pressure gauge adapter from the fuel rail. Use a shop towel in order to catch any remaining fuel that may leak.

NOTE: Refer to Fastener Notice in Cautions and Notices.




4. Install the fuel rail plug bolt (1) and a new gasket to the fuel rail.

Tighten
Tighten the fuel rail plug bolt to 30 N.m (22 lb ft).

5. Connect the negative battery cable.

Tighten
Tighten the negative battery cable terminal retainer to 8 N.m ( 72 lb in).

6. Turn ON the ignition in order to pressurize the fuel system.
7. Turn OFF the ignition.
8. Check for any fuel leaks and repair as necessary.


INSTALLATION PROCEDURE





TOOLS REQUIRED
^ J 34730-1A Fuel Pressure Gauge
^ J 41041 Fuel Pressure Gauge Adapter

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

CAUTION: Refer to Battery Disconnect Caution in Cautions and Notices.

2. Disconnect the negative battery cable.
3. Remove the fuel plug bolt (1) from the end of the fuel rail.




4. Install the J 41041 fuel pressure gauge adapter to fuel rail.
5. Install the J 34730-1A fuel pressure gauge to the J 41041 fuel pressure gauge adapter.

NOTE: Refer to Fastener Notice in Cautions and Notices.

6. Connect the negative battery cable.

Tighten
Tighten the negative battery cable terminal retainer to 8 N.m ( 72 lb in).

7. Turn ON the ignition in order to pressurize the fuel system.
8. Turn OFF the ignition.
9. Check for any fuel leaks and repair as necessary.
10. Start the engine.
11. Idle the engine at the normal operating temperature.
12. Check the fuel pressure as follows:
^ 210-260 kPa (30-37 psi) with the engine idling.
^ 250-300 kPa (36-43 psi) when the engine is not running and the ignition switch is On - FUEL PUMP IS RUNNING.
^ The fuel pressure should hold at or above 180 kPa (26 psi) within one minute of the engine not running while the ignition switch is Off - FUEL PUMP IS NOT RUNNING.
13. If the fuel pressure is not within the correct specifications, refer to Fuel System Diagnosis.
