Because the gasoline is volatile, when the tank part of the gasoline after gasification, will be the pressure inside the tank, when the 120kpa is reached when the steam valve will open, the discharge of gasoline steam, through the activated carbon tank and discharged by the exhaust pipe. The impact on the safety of the pipeline is responsible for the discharge of gasoline steam.
