ABSTRACT:
An apparatus for preventing discharge of fuel vapor to the atmosphere by allowing fuel vapor in a fuel tank to be adsorbed by an adsorbing device when a fuel lid is opened. A switch is secured to a mounting bracket for rotatably supporting a fuel lid opener lever mounted in a vehicle compartment. The switch is turned on by the operation of the remote lever that opens the fuel lid, and fuel vapor is adsorbed by charcoal in a canister. The switch is adjustably secured to the mounting bracket, to facilitate positioning the pushbutton of the switch relative to the lid opening lever.
