Abstract: A fuel dispensing nozzle is provided with fuel activated levers that engage the vehicle fill pipe to prevent drive-off without paying. Fuel pump pressure acts on plungers to pivot fill pipe levers, against spring pressure, to lock the two together. Movement of the levers is initially prevented by a trigger that is spring biased forward on the nozzle spout. Since the fill pipe is not large enough to pass the trigger, insertion of the spout into the fill pipe moves the trigger against spring pressure to uncover the levers. The levers are locked to the fill pipe as long as pump pressure is present. Removal of fuel pressure allows the levers to be withdrawn by spring action. A breakaway joint is provided to stop fuel flow in the event of drive-off with the fuel nozzle in a fuel filled pipe.
