A cover for a filler neck includes a body portion and a movable protective door that covers and exposes an opening in the filler neck. The protective door includes a ledge that protrudes from the plane of the door so that the door can be easily moved to an open position by pressing a tip of a fuel nozzle against the door. The door itself may be biased to move into a closed position automatically when the fuel nozzle is removed from the ledge.
