A fuel cap (10) and filler neck fitment (14) for receiving the fuel cap. The fuel cap includes an outer member (18) and an inner closure assembly (20) with seal. The cap and fitment both include lugs (28, 36) which interengage when the cap is moved into a closing position to pressurize the seal determined by an improved overriding ratchet arrangement. During removal of the cap, the outer member moves against a spring action for a predetermined arc before the inner closure assembly is moved to disengage the seal. When the seal is disengaged, the spring action takes up the relative motion. Once removed, the cap is retained by an improved tether (74) assembly. The outer member is connected to the inner annular assembly by an improved structural arrangement which allows the outer member to separate under crash impact.
