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.

What is claimed is: 1. A fuel water separator system, comprising: a fuel tank for storing fuel; a fuel water separator fluidly coupled to the fuel tank for separating water from the fuel; a fuel pump having a suction side that is fluidly coupled to the fuel water separator for pumping fuel from the fuel water separator, the fuel pump having a high pressure side where the fuel has a higher pressure than at the suction side; a water pump integrated into the fuel water separator, the water pump fluidly coupled between the fuel water separator and the fuel tank for pumping the water from the fuel water separator into the fuel tank; and a pressure filter fluidly coupled to the high pressure side of the fuel pump for filtering the fuel, wherein the water pump is fluidly coupled to the high pressure side of the fuel pump at the pressure filter to receive the fuel at the higher pressure to drive the water pump. 2. The system of claim 1, wherein the water pump includes a venturi pump. 3. The system of claim 1, wherein the water pump includes a jet pump. 4. The system of claim 1, wherein the fuel tank includes a drain valve for draining the water from the fuel tank. 5. The system of claim 4, wherein the drain valve includes a manually operated type valve. 6. The system of claim 1, wherein the fuel water separator includes filter media for separating the water from the fuel. 7. The system of claim 1, further comprising a strainer disposed in the fuel water separator for filtering contaminants from the water before entry into the water pump. 8. The system of claim 1, wherein the water pump includes a back flow valve having a cracking pressure that minimizes back flow of the fuel. 9. The system of claim 8, wherein the back flow valve includes a check valve. 10. The system of claim 1, wherein the pressure filter includes an air vent for venting air from the pressure filter; and the water pump is fluidly coupled to the air vent to receive the fuel at the higher pressure. 11. The system of claim 1, further comprising an engine fluidly coupled to the pressure filter. 12. The system of claim 1, further comprising a settling tank fluidly coupled between the water pump and the fuel tank for collecting the water. 13. A fuel water separator system, comprising: a fuel pump configured to pump fuel, the fuel pump having a high pressure side and a suction side where the fuel has a pressure lower than at the high pressure side; a fuel water separator configured to separate water from the fuel, the fuel water separator being fluidly coupled to the suction side of the fuel pump, the fuel water separator having a pump portion with a drain opening through which the water is drained; a high pressure filter fluidly coupled to the high pressure side of the fuel pump for filtering the fuel, the high pressure filter having a top portion with an air vent passage configured to vent air from the high pressure filter; and a venturi with an inlet port fluidly coupled to the vent passage so that the fuel flow through the venturi is negligible during cold cranking of an engine and an outlet port fluidly coupled to a remote storage location, the venturi having an injection port fluidly coupled to the drain opening to pump the water from the pump portion of the fuel water separator when the fuel flows through the venturi. 14. The system of claim 13, wherein the inlet port and the outlet port taper toward a narrow throat portion for creating suction at the injection port. 15. A fuel pump system, comprising: a fuel water separator configured to separate water from fuel; a fuel pump configured to pump the fuel, the fuel pump having a suction port fluidly coupled to the fuel water separator and a high pressure port where the fuel has a pressure higher than at the suction port; a jet pump including an inlet port fluidly coupled to the high pressure port, an injection port fluidly coupled to the fuel water separator to receive water from the fuel water separator, a jet orifice disposed between the inlet port and the injection port, the jet orifice being sized smaller than the inlet port to create a jet of the fuel for drawing the water through the injection port, and a discharge port from which a mixture of the fuel from the jet and the water is discharged; a storage container fluidly coupled to the discharge port of the jet pump for storing the water from the jet pump; and a filter fluidly coupled to the high pressure port of the fuel pump to filter the fuel, wherein the inlet port of the jet pump is fluidly coupled to the high pressure port through the filter. 16. The system of claim 15, wherein the storage container includes a fuel tank. 17. A fuel water separator system, comprising: means for separating water from fuel; means for increasing pressure of the fuel from said means for separating the water from the fuel; means for pumping the water from said means for separating the water from the fuel, wherein said means for pumping the water is driven by the fuel with increased pressure from said means for increasing the pressure of the fuel; means for housing supporting the means for separating water from fuel and the means for pumping water, wherein the means for pumping water is adjacent to the means for separating water from fuel, and wherein the means for pumping receives the water directly from the means for separating water from fuel; means for storing the water from said means for pumping the water; and means for filtering the fuel from said means for increasing the pressure of the fuel, wherein said means for pumping the water receives the fuel from said means for filtering the fuel. 18. The system of claim 17, wherein: said means for separating the water from the fuel includes a fuel water separator; said means for increasing the pressure of the fuel includes a fuel pump; said means for pumping the water includes a jet pump; said means for storing the water includes a fuel tank; and said means for filtering the fuel includes a high pressure filter.
