Abstract: An automatic gas cap actuator system (10, 10?) for automatic locking and opening of the gas cap (26, 74) of a vehicle's fuel tank is provided. The system (10, 10?) has a gas cap (26, 74); and a cap actuator (16, 20, 48, 48?; 72) actuated by a non-manual power source (12, 12?). The cap actuator interfaces with the gas cap (26, 74) via an interface (39, 76) in a manner so as to be able to impart relative rotation between the gas cap and a fixing element (20, 78), so as to draw the cap into engagement with the filling tube (34, 52), the interface and the gas cap being disengageable so as to permit manual use at the will of the operator. A remote controller within reach of a vehicle operator actuates the motor (12, 12?). In an advantage, the cap (26, 74) can be locked or opened both electrically and manually. Using the electrical unlock, the cap (26, 74) unlocks and opens without any necessary manual intervention.
