ABSTRACT:
A fuel water separator system includes a fuel tank for storing fuel and a fuel water separator fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side that is fluidly coupled to the fuel water separator for pumping fuel from the fuel water separator. The fuel pump has a high pressure side where the fuel has a higher pressure than at the suction side. A water pump, such as a venturi or a jet pump, is fluidly coupled between the fuel water separator and the fuel tank for pumping the water from the fuel water separator into the fuel tank. The water pump is fluidly coupled to the high pressure side of the fuel pump to receive the fuel at the higher pressure to drive the water pump.
