Abstract
A fuel system provides first and second conduits that draw fuel from first and second positions, or locations, within a fuel reservoir. If water exists in the fuel reservoir, the second position is selected to be lowered in the fuel reservoir than the first position so that accumulated water will be drawn through the second conduit under certain conditions, such as when the engine is operating at a speed above the minimum threshold. The fuel reservoir can be a fuel tank or auxiliary fuel tank of a vehicle or watercraft or, alternatively, it can be the housing of a fuel/water separator.
