ABSTRACT:
A fuel tank includes a main tank portion and a sub-tank portion. The returned fuel returned from an internal combustion engine is returned through a return passage to each of the tank portions. The return passage is equipped with a distributing valve for adjusting the volume of the returned fuel to be returned to the main tank portion and the sub-tank portion according to the fuel temperature within the sub-tank portion. For example, when the fuel temperature within the sub-tank portion is lower than boiling point of the fuel, the distributing valve is controlled to return all of the returned fuel to the sub-tank portion, and when the fuel temperature is more than the boiling point of the fuel, the distributing valve is controlled to return the returned fuel to both tanks. Accordingly, it is possible to prevent the evapotranspiration of fuel.
