1.INSPECTION START Do you have CONSULT-III? Do you have CONSULT-III? YES>>GO TO 2. NO>>GO TO 3.
2.CHECK REFUELING EVAP VAPOR CUT VALVE
With CONSULT-III

1. Turn ignition switch OFF.
2. Remove fuel tank. Refer to Removal and Installation (GT-R certified NISSAN dealer).
3. Drain fuel from the tank as follows:

- Remove fuel feed hose located on the fuel gauge retainer.
- Connect a spare fuel hose, one side to fuel gauge retainer where the hose was removed and the other side to a fuel container.
- Drain fuel using “FUEL PUMP RELAY” in “ACTIVE TEST” mode with CONSULT-III.

4. Check refueling EVAP vapor cut valve for being stuck to close as follows.Blow air into the refueling EVAP vapor cut valve (from the end of EVAP/ORVR line hose), and check that the air flows freely into the tank.
5. Check refueling EVAP vapor cut valve for being stuck to open as follows.

- Connect vacuum pump to hose end.
- Remove fuel gauge retainer with fuel gauge unit.Always replace O-ring with new one.
- Turn fuel tank upside down.
- Apply vacuum pressure to hose end [−13.3 kPa (−0.136 kg/cm2, −1.93 psi)] with fuel gauge retainer remaining open and check that the pressure is applicable.

Is the inspection result normal?
YES>>INSPECTION END
NO>>Replace refueling EVAP vapor cut valve with fuel tank.
