Abstract: An apparatus for slidably moving a valve control member adjacent a fuel neck of a fuel tank without generating transverse forces. The apparatus provides a slide engaging the valve control member and a toggle lever one arm of which slidably engages a pivotal lid in the fuel neck and the other arm of which is mounted for pivoting about an axis parallel to the pivot axis of the lid. The junction between the arms of the toggle lever engages the slide and converts the pivotal movement of the lid into linear movement of the slide and the valve control member.
