A fuel cap (10) is provided for a filler neck (26). Fuel cap (10) includes a core (24), a sleeve (14) positioned around core (24), and a seal (130) coupled to the core (24). Sleeve (14) includes a sealing surface (76) and a recessed surface (78) that is axially lower and radially outward of sealing surface (76). As core (24) rotates, sleeve (14) moves further into filler neck (26) from an upper position to a lower position. While sleeve (14) is in the upper position, seal (130) is adjacent to recessed surface (78) so that a gap (136) exists between sleeve (14) and seal (130). As sleeve (14) moves to the lower position, seal (130) moves relative to sleeve (14) to a position engaging sealing surface (76) to block flow between core (24) and sleeve (14).
