Tools Required

A fuel system pressure test determines if the fuel delivery system is functioning correctly from a fluid (gasoline) perspective. To perform this test, follow the procedure below.

1. Relieve the fuel system pressure. Refer to Fuel Pressure Gage Installation and Removal.
2. Remove the one bolt.
3. Remove the fuel feed hose bracket from the bottom of the intake manifold.
4. Remove the one bolt.
5. Remove the fuel feed hose (2) from the fuel rail.
6. Install the J 39802-A (3) with the gaskets and the fuel feed hose to the fuel rail.

Tighten
Tighten the J 39802-A bolt to 29 N·m (22 lb ft).

7. Connect the J 34730-1A to the J 39802-A.

1. Relieve the fuel system pressure. Refer to Fuel Pressure Gage Installation and Removal.
2. Remove the one bolt and the J 39802-A (3) and the J 34730-1A  (1) from the fuel rail.
3. Using the two new gaskets, reconnect the fuel feed hose to the fuel rail.
4. Secure the fuel feed hose with one bolt.

Tighten
Tighten the fuel feed hose bolt to 29 N·m (22 lb ft).

5. Reconnect the fuel feed bracket with one bolt.
6. Secure the fuel feed bracket with one bolt.

Tighten
Tighten the fuel feed hose bracket bolt to 9.3 N·m (82 lb in).

7. Turn the ignition switch to the ON position and momentarily connect a jumper between DLC terminals +B and Fp to pressurize the fuel system. Check for any fuel leaks.
