As the tank fills, the fuel level begins to lift float (3). When float (3) rises, the float blocks signal line (4). As signal line (4) builds pressure, shutoff valve (5) closes, and the flow of fuel to the tank is blocked. The fuel nozzle disengages due to back pressure. When float (3) is in the UP position, shutoff valve (5) is hydraulically locked and fuel can not be pumped into the tank.
