After long time since engine stopped, the temperature in the fuel tank will rise (Since the vehicle doesn’t
move, the dynamic ventilation is not enough.) and the pressure in the fuel tank will rise.
—— When the fuel tank is full, the multi-function valve 4 is closed. The fuel cannot flow into charcoal
canister 6, therefore it doesn’t damage charcoal canister.
