Electrically controlled refueling vapor vent shutoff

DRIVE June 9, 2004
Source
An electrically operated valve (70) is connected in the vapor recirculation line (74) from a float operated vent valve (32), or a direct vapor recirculation line from the tank top to the upper end of the tank filler tube (24). The electrically operated valve (70) is actuated by an electronic controller (ECU) (68) which receives a fuel level signal either from the float operated level sender (62) or from a thermistor located in the tank adjacent the top wall of the tank. The electrically operated valve (70) is closed as soon as the fuel level reaches a predetermined level.
