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.

Fuel tank

A system and method for supplying fuel to an internal combustion engine is disclosed including a fuel tank having a first fuel sump portion , in which a fuel pump is disposed, and a second fuel sump portion formed separate from the first fuel sump portion . A transfer pump which supplies fuel from the second fuel sump portion to the first fuel sump portion 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 . A divergent fuel control unit 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 as a whole and the flow rate size thereof.
