ABSTRACT:
A liquid dispensing and vapor recovery system in which an underground storage tank is connected to a first conduit for delivering a liquid, such as gasoline, to a vehicle gasoline tank or the like under the force of a pump located in the storage tank. A second conduit is connected to the first conduit and to the storage tank for diverting a portion of the gasoline in the first conduit back to the storage tank and an injector is located in the second conduit for forming a reduced pressure zone in response to gasoline flow through the second conduit. A valve unit prevents the flow of gasoline through the second conduit until gasoline is delivered to the vehicle gasoline tank. A third conduit is connected to the vehicle tank and to the second conduit at the reduced pressure zone for drawing the vapors from the vehicle tank into the second conduit for passage into the storage tank.
