A device is provided to prevent the accidental introduction of an incorrect liquid into a tank, such as the introduction of gasoline into the fuel system of a diesel fuel container. The device discriminates between nozzle diameters, allowing entrance of nozzle diameters at or greater than a predetermined minimum diameter while inhibiting entrance of nozzles having diameters less than the predetermined minimum diameter. A closure mechanism prevents access to a fuel container interior and a releasable locking mechanism responsive to nozzle diameters allows the closure mechanism to open and close to allow access to the fuel container interior.
