A fuel filler closure device for an automotive vehicle includes a valve body adapted for mounting to a fuel filler pipe and having a filler passage. An access door mounted within the valve body has an open position allowing placement of a fuel nozzle within the filler passage and a closed position for blocking insertion of a filler nozzle. The locking mechanism selectively permits the access door to move from the closed position to the open position. The locking mechanism may include either a manual locking device, or an electronic or other type of remote lock which will be responsive to a vehicle condition.
