Abstract
The present invention provides a fuel delivery system capable of controlling a fuel dispenser's vapor recovery system based on the absence or presence of an on-board vapor recovery system on the vehicle. This system includes a fuel dispenser having a vapor recovery system, a controller capable of controlling the vapor recovery system, a receiver and an antenna operating in conjunction with the receiver to receive a signal emitted from a transponder on a vehicle indicative of the absence or presence of an on-board vapor recovery system, in addition to a type of vehicle tank or characteristic thereof. When the controller determines from the transponder signal information relating to on-board vapor recovery and/or tank characteristics, the controller will control its vapor recovery system accordingly.
