Claim 8:
9. The vapor recovery system of claim 8, further comprising
i. a control valve having a pilot valve, a flow gate, a central shaft conduit, and a spring seat securing a control spring, wherein said control valve is positioned in said upper central cylindrical conduit and said control spring interfaces with said housing collar; and
ii.
iii. a lower housing cap having a vapor return line and an ullage pressure port, and is operable to secure a lower housing gasket to said housing body and provide a fluid-tight seal,
wherein said diaphragm assembly is normally open and during a fuel operation liquid fuel fills said upper central cylindrical conduit and provides a fluid pressure operable to overcome the control spring bias and allows liquid fuel to pass through said fuel gate to said aerator for developing a uniform flow to said converging nozzle and rapidly expanding in said mixing chamber thereby generating a vacuum on said surge chamber and depositing said fluid vapor mixture into said storage tank.
