The invention is a cap engagable with a filler neck of a vehicle fuel tank, the cap having a core including an axially lower end, an axially upper end, and an exterior side wall extending between the axially lower and upper ends. A handle is coupled adjacent the axially upper end of the core and adapted to rotate the core about an axis of rotation between a loosened position permitting removal of the core from the filler neck and a tightened position securing the core within the filler neck. The cap further includes a seal positioned to lie around the core and a sleeve movable axially by the handle. The sleeve and has an interior side wall defining a chamber formed in the sleeve. The core lies within the chamber, and the seal lies between the sleeve and the core. A gap is formed between the seal and the interior side wall of the sleeve during rotation of the core relative to the filler neck from the loosened position to the tightened position, and the gap is eliminated when the cap is in the tightened position.
