A cap (50) that is engageable with a tank filler neck (52) includes a closure (56), handle (54), and an annular gasket (76) on an axially inner end of closure (56) in spaced-apart relation to handle (54) and closure retainer apparatus (70) mounted on closure (56). Closure (56) includes an upper housing (62) carrying closure retainer apparatus (70) and a lower housing (66) rotatably coupled to upper housing (62) and carrying annular gasket (76) and an anti-rotation lug (68) positioned to engage filler neck (52) during cap installation. A delayed actuator mechanism (58) rotatably couples handle (54) to upper housing (62) to provide a lost-motion driving connection in a cap-removal direction (166) and a direct-drive connection in the cap-installation direction (164). Annular gasket (76) includes an annular outer seal (122), a hoop-shaped base (120), and a thin annular multi-directional membrane (124) interconnecting hoop-shaped base (120) and the surrounding annular outer seal (122).

[ What is claimed is:] [1.] A cap engageable with a filler neck of a vehicle fuel tank, the cap comprisinga closure for closing the filler neck, the closure including a generally cylindrical side wall having an axially inner end, an axially outer end, and closure retainer apparatus configured to rotationally engage the filler neck when the cap is installed in the filler neck to block removal of the closure from the filler neck,a handle connected to the axially outer end of the closure for moving the closure relative to the filler neck, andan annular gasket received by the side wall of the closure at the axially inner end, the closure retainer apparatus being axially positioned to lie between the gasket and the axially outer end of the closure, the closure including an upper housing carrying the closure retainer apparatus and an axially inner lower housing rotatably coupled to the upper housing so that the upper housing can rotate about an axis of rotation relative to the lower housing when the handle is rotated about the axis of rotation.
