The AirDog Fuel Preporator, with the capability to provide fuel at flows and pressures beyond the maximum requirements of the engine, receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of moisture. The fuel passes through the water separator which removes the water and large particulate contaminates that could damage or jam the gearator fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump.
