The system receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water. The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam The gerotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining enters the AirDog II fuel pump. The fuel, under positive pressure flow, enters the second stage fuel filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained & free of contaminates & power robbing air/vapor and at pressures and flows always able to meet the needs of the engine, exits the fuel filter & passes into the fuel pickup tube and on to the engine.
