The filler neck cap of claim 1, wherein the handle-rotation travel-limit means includes an anti-rotation stop coupled to the closure to rotate therewith and a rotation-inhibitor tab coupled to the outer handle to rotate therewith and to engage the anti-rotation stop to block further rotation of the outer handle in the cap-advancing direction relative to the closure that is stationary in the closure hard-stop position when the outer handle reaches the handle hard-stop position. 3. The filler neck cap of claim 2, wherein the anti-rotation stop is arranged to lie in spaced-apart relation to the torque-transmission member to locate a portion of the torque receiver therebetween. 4. The filler neck cap of claim 3, wherein the torque receiver is arc-shaped and includes a series of circumferentially spaced-apart tooth mounts and each torque tooth is coupled to a pair of adjacent tooth mounts and arranged to extend radially inwardly toward the axis of rotation to engage the deflectable closure rotator during rotation of the torque-transmission member about the axis of rotation relative to the closure. 5. The filler neck cap of claim 4, wherein the anti-rotation stop is coupled to one of the tooth mounts. 6. The filler neck cap of claim 2, wherein the base of the closure includes a barrel arranged to extend axially along the axis of rotation and an annular plate coupled to an upper end of the barrel and arranged to lie in a position between the barrel and a top wall of the outer handle and the torque receiver is coupled to an upwardly facing surface of the annular plate and arranged to extend upwardly away from the barrel and to surround the torque-transmission member. 7. The filler neck cap of claim 6, wherein each torque tooth is arranged to extend in a radially inward direction toward the axis of rotation. 8. The filler neck cap of claim 6, wherein the anti-rotation stop is coupled to the upwardly facing surface of the annular plate. 9. The filler neck cap of claim 8, wherein the anti-rotation stop is also coupled to one of the torque teeth and arranged to extend in a radially outward direction away from the axis of rotation. 10. The filler neck cap of claim 8, wherein the outer handle includes a top wall arranged to overlie the torque-transmission member and a side wall coupled to a peripheral portion of the top wall and arranged to surround a perimeter edge of the top plate to locate the anti-rotation stop in a space provided between the torque receiver and the side wall of the outer handle, and the rotation-inhibitor tab is coupled to the side wall to extend in a radially inward direction toward the axis of rotation and is arranged to mate with the anti-rotation stop in response to rotation of the outer handle to the handle hard-stop position when the base of the closure is in the closure hard-stop position. 11. The filler neck cap of claim 2, wherein the outer handle includes a top wall arranged to overlie the torque-transmission member and a side wall coupled to a peripheral portion of the top wall and arranged to extend downwardly from the top wall to surround an upper portion of the base of the closure and the rotation-inhibitor tab is coupled to an inner surface of the side wall of the handle and arranged to extend radially inwardly toward the axis of rotation to mate with the anti-rotation stop once the outer handle is rotated to reach the handle hard-stop position. 12. The filler neck cap of claim 6, wherein a torque tooth included in the torque receiver is positioned to lie between the rotation-inhibitor tab and the torque-transmission member once the outer handle is rotated to reach the handle hard-stop position. 13. The filler neck cap of claim 12, wherein the anti-rotation stop is positioned to lie between the torque receiver and the side wall of the outer handle. 14. The filler neck cap of claim 1, wherein the handle-rotation travel-limit means includes a handle-locator stop coupled to the closure to rotate therewith, a handle-locator tab coupled to the outer handle to rotate therewith, and a torsion spring coupled to the outer handle and to the closure and arranged to extend through a central aperture formed in the torque-transmission member, and the torsion spring is configured to provide handle-reset means for automatically rotating the closure about the axis of rotation relative to the outer handle in a cap-removal direction opposite to the cap-advancing direction while a user is gripping the outer handle as soon as the base of the closure is separated from the filler neck during a cap-removal activity to cause the handle-locator stop to move to engage the handle-locator tab to block further rotation of the closure relative to the outer handle to establish a ready-to-install position of the closure relative to the outer handle in the cap-advancing direction to reach the closure hard-stop position in the filler neck and before the outer handle is rotated about the axis of rotation in the cap-advancing position to reach the handle hard-stop position. 15. The filler neck cap of claim 14, wherein the torque receiver includes three torque teeth arranged to be engaged in sequence by the deflectable closure rotator to produce in sequence three separate discernable warning signals during rotation of the outer handle relative to the closure from the initial position to the handle hard-stop position. 16. The filler neck cap of claim 1, wherein the closure further includes a rotation-inhibitor tab coupled to the base to rotate therewith relative to the filler neck and configured to provide means for engaging an anti-rotation stop included in the filler neck upon arrival of the base of the closure at the closure hard-stop position in the filler neck so that further rotation of the base about the axis of rotation relative to the filler neck is blocked during continued rotation of the outer handle about the axis of rotation in the cap-advancing direction. 17. The filler neck cap of claim 1, wherein the central hub of the torque-transmission member is formed to include a central aperture through which the axis of rotation extends, outer handle includes a ring of radially inwardly extending torque teeth, and the torque-transmission member further includes a ratchet arm cantilevered at one end thereof to the central hub and located I the central aperture formed in the central aperture to mate with the ring of radially inwardly extending torque teeth to provide means for transferring torque applied by a cap installer to the outer handle to the torque-transmission member so that the torque-transmission member rotates relative to the outer handle during a cap-installation activity. 18. The filler neck cap of claim 17, wherein the handle-rotation travel-limit means includes a handle-locator stop coupled to the closure to rotate therewith, a handle-locator tab coupled to the outer handle to rotate therewith, and a torsion spring coupled to the outer handle and to the closure and arranged to extend through a central aperture formed in the torque-transmission member, and the torsion spring is configured to provide handle-reset means for automatically rotating the closure about the axis of rotation relative to the outer handle in a cap-removal direction opposite to the cap-advancing direction while a user is gripping the outer handle as soon as the base of the closure is separated from the filler neck during a cap-removal activity to cause the handle-locator stop to move to engage the handle-locator tab to block further rotation of the closure relative to the outer handle to establish a ready-to-install position of the closure relative to the outer handle in the cap-advancing direction to reach the closure hard-stop position in the filler neck and before the outer handle is rotated about the axis of rotation in the cap-advancing position to reach the handle hard-stop position, and the ratchet arm is configured to slip and move relative to the ring of radially inwardly extending torque teeth without transferring torque between the outer handle and the torque-transmission member during automatic rotation of the closure about the axis of rotation relative to the outer handle in the cap-removal direction.
