Zusammenfassung:PURPOSE:To reduce discharge of a gasoline vapor during oil feeding and being left for a long time. CONSTITUTION:When an engine is stopped for oil feeding just after travel of a vehicle, a temperature sensitive valve 7 and a one directional valve 6 are closed. As an intake pipe negative pressure during travel is left in a diaphragm chamber 9 of a tank inner pressure controlling valve 3, a valve 14 is left open for a while and an inner pressure of a fuel tank is low. When the vehicle is left as it is after oil feeding, an engine temperature is gradually lowered and the valve 14 is closed gradually. Therefore, a fuel tank inner pressure is increased.
