A vapor recovery system for a fuel dispenser having a valve positioned in the hanging hardware for testing for leaks along a vapor recovery line. Vapor valves placed along the vapor recovery line allow for isolating sections of the recovery line to determine the position of any leaks. A vapor pump positioned on the vapor recovery line provides for changing the pressure within the line and a vapor sensor positioned on the vapor recovery line determines the amount of pressure within the line. A control system controls the vapor pump and valves and receives signals from the pressure sensor for determining the position of leaks along the vapor recovery line.

1. A system for detecting leaks within a vapor recovery system comprising:a fuel dispenser having hanging hardware; a vapor recovery line extending through said fuel dispenser and hanging hardware; a valve located in said vapor recovery path within said hanging hardware and being selectively positionable between an open position allowing vapor flow through said vapor recovery line and a closed position blocking vapor flow through said vapor recovery line depending upon the orientation of said hanging hardware; a vapor pump operatively associated with the vapor recovery line; a pressure sensor connected in the vapor recovery line between said valve and said vapor pump; a control system operatively connected to said pressure sensor and said vapor pump, said control system activating said vapor pump when said valve is in said closed position and receiving a signal from said pressure sensor indicative of the pressure along said vapor recovery line; a fuel dispenser housing for containing said hanging hardware when not in use, said hanging hardware being placed in an upright position with said valve in said closed orientation; and a sensor positioned within said fuel dispenser housing for sensing the presence of said hanging hardware, said sensor operatively connected to said control system.
