The system includes a fuel storage tank connected to a vacuum pump by a supply line, a fuel/water separator, a fuel lift pump, a fuel/water return line and a fuel injector pump or carburetor. The fuel/water separator includes a coalescer interposed between the fuel lift pump and the injector pump or carburetor to separate the water from the fuel. Water collects in the lowest portion of the separator housing, is removed through an orifice in the fuel/water return line, and is routed back to the fuel tank. With moderate levels of water contamination in the fuel tank the system prevents water from reaching the fuel injector pump or carburetor for an indefinite period of time. The separator housing is constantly drained since the separator is under pressure. The system has a suitable detector to detect the water level in the fuel storage tank. Water may be removed from the fuel storage tank by temporarily converting a part of the water/fuel return line to a water outlet pumping line through a three-way valve.
