Abstract
Drive off is prevented by having a grasp assembly engage the restrictor plate of the fill pipe of a motor vehicle when the nozzle spout is inserted. After the fuel pump is started and pressure is placed on the fuel, fuel is admitted into the nozzle by pressing on the hand lever to open the poppet valve. Fuel pressure in the nozzle activates a lock actuator system, to prevent removal of the spout from the fill pipe, by a lock system that prevents a grasp assembly latch from retracting from the fill pipe restrictor plate.
