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.
