A closure assembly (10) includes a filler neck (12), a housing (18), and an appearance cover (16). Housing (18) includes a nozzle-receiving passageway (84) and an interior region (64). A closure door (24) is coupled to housing (18) and prevents fuel vapor from flowing through passageway (84). A pressur e- relief valve assembly (22) is positioned within interior region (64) and controls the flow of fuel vapor through interior region (64) when closure do or (24) is closed. A valve actuator (80) is coupled to housing (18) and include s a nozzle arm (83), a stem arm (85), and a conductor arm (86). Stem arm (85) moves with nozzle arm (83) and opens pressure-relief valve assembly (22) whe n nozzle arm (83) is engaged by a fuel-dispensing nozzle upon movement of a nozzle into passageway (84). Conductor arm (86) is coupled to nozzle arm (83 ) and is positioned to contact filler neck (12) through an opening (87) in housing (18). When a nozzle contacts nozzle arm (83), electrical charge present on fuel-dispensing nozzle is conducted through nozzle arm (83) and conductor arm (86) to filler neck (12).
