ABSTRACT:
In a vehicle driven by a diesel engine, a sensor is activated by an accumulation of water in the fuel tank and another sensor is activated when the engine temperature is at a level, less than normal operating level, indicating that the vehicle and its fuel tank have been stationary for a period sufficient to permit separation of the fuel from the water in the tank. A solenoid is energized upon activation of both sensors and opens a drain valve to permit the water to be drained from the tank.
