Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace fuel filler tube or replace one-way fuel valve with fuel tank.
1.INSPECTION START
Do you have CONSULT?
YES >> GO TO 2.
NO >> GO TO 3.
2.CHECK REFUELING EVAP VAPOR CUT VALVE
With CONSULT
- 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 of "ENGINE" using CONSULT.
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.
- Connect vacuum pump to hose end.
- Remove fuel gauge retainer with fuel gauge unit.
Always replace O-ring with new one.
- Put fuel tank upside down.
- Apply vacuum pressure to hose end [−13.3 kPa (−0.136 kg/cm3, −1.93 psi)] with fuel gauge retainer remaining open and check that the pressure is applicable.
1. Filler tube 2. Recirculation line 3. EVAP/ORVR line 4. Vacuum/pressure handy pump 5. Fuel tank
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace refueling EVAP vapor cut valve with fuel tank. Refer to FL, "Removal and Installation".
3.CHECK REFUELING EVAP VAPOR CUT VALVE
Without CONSULT
- Remove fuel gauge retainer.
- Drain fuel from the tank using a handy pump into a fuel container.
