FUEL SHUT-OFF VALVE [SKYACTIV-G 2.5]

U.S.A. And CANADA

Purpose, function

• Prevents fuel from flowing to the charcoal canister during tight turns or vehicle rollover.

• Releases evaporative gas to the charcoal canister.

• While refueling, the fuel shut-off valve closes to prevent a fuel overflow.

Construction

• The fuel shut-off valve is built into the fuel tank.

  

• The fuel shut-off valve consists of float and spring.

  

Operation

• While refueling or due to fuel sloshing, the float is flooded with fuel and the floating force causes the valve to close. Also, during a vehicle rollover, the valve closes due to balance between the float gravity and spring.
