Abstract: A fuel tank has a primary sump and secondary sump. A first vent valve and a second vent valve are disposed within the fuel tank. The first vent valve is closed when a level of fuel in the primary sump is equal to or higher than a first predetermined filling level, and the second vent valve is closed when a level of fuel in the secondary sump is equal to or higher than a second predetermined filling level in a refueling procedure.

Abstract: A system and method for supplying fuel to an internal combustion engine is disclosed including a fuel tank 11 having a first fuel sump portion 11a, in which a fuel pump 12 is disposed, and a second fuel sump portion 11b formed separate from the first fuel sump portion 11a. A transfer pump 17 which supplies fuel from the second fuel sump portion 11b to the first fuel sump portion 11a is driven with a traveling energy of divergent fuel forming a portion of fuel to be supplied to the internal combustion engine from the fuel pump 12. A divergent fuel control unit 20 is disposed in a supply line of the diverged fuel to decrease the flow rate of the divergent fuel in dependence on an increase in a demanded fuel flow rate of the internal combustion engine, thereby minimizing a compensation flow rate of the fuel pump 12 as a whole and the flow rate size thereof.
