Abstract
A lockable pressure-release fuel cap is provided to close a filler neck. An actuation system within the fuel cap is operable to enable a user to vent fuel vapor pressure in the filler neck in response to rotation of a key in a lock unit included in the fuel cap prior to removal of the fuel cap from the filler neck.
