SERVICE INFORMATION





If the fuel pressure on an applied vehicle needs to be checked, use Fuel Pressure Gauge kit J-44321. This kit is an essential tool and will be sent to each dealer.

The following Service Procedure provides fuel pressure gauge connecting instructions for each applied vehicle.

NOTE:
For vehicles that have the hose-clamp type fuel line connections, use the hose-clamp type quick connect hose (see Figure 7).

SERVICE PROCEDURE

Fuel Pressure Gauge Connection for 2000-2001 I30

1. Release fuel pressure from the fuel system. Refer to the "Fuel Pressure Release Procedure".





2. Temporarily disconnect three hoses as shown in Figure 1.





3. Install the Inline Fuel Quick Disconnect fitting between the fuel damper and the fuel tube (see Figure 2).

CAUTION:
Do not over tighten the bolts when installing the Inline Fuel Quick Disconnect fitting.

NOTE:
Apply Canopus 13 oil (P/N 999MP-AJ000) to the 0-ring on the Quick Disconnect fitting and the fuel damper before installation (see Figure 2).

4. Connect the fuel pressure test gauge (Quick Connect adapter hose) to the Quick Disconnect fitting (see Figure 2).

5. Perform the fuel pressure test.

6. Release fuel pressure from the fuel system. Refer to the "Fuel Pressure Release Procedure".

7. Remove the Quick Disconnect fitting.

8. Again, apply Canopus 13 oil to the fuel damper 0-ring.

9. Re-install the fuel damper to the fuel tube.

10. Re-connect the three hoses as shown in Figure 1

11. Operate the fuel system and confirm there are NO fuel leaks.

Fuel Pressure Release Procedure

With CONSULT-II

1. Turn the ignition switch "ON".

2. Connect CONSULT-II and perform the "Fuel Pressure Release" function in the "Work Support Mode".

3. Start the engine and let it run until it stalls.

4. Crank the engine two or three times to release all fuel pressure.

5. Turn the ignition switch "OFF".

Without CONSULT-II

1. Remove the fuel pump fuse from the fuse box.

2. Start the engine and let it run until it stalls.

3. Crank the engine two or three times to release all fuel pressure.

4. Turn the ignition switch "OFF".

5. Re-install the fuel pump fuse AFTER connecting the fuel pressure gauge.
