An apparatus for testing the efficiency of the vapor recovery of a liquid dispensing and vapor recovery system wherein the system uses a spout with vapor recovery apertures. The apparatus includes a device for receiving the spout and its vapor recovery apertures with a space located therebetween. A sealing device is connected to the spout receiving device for providing a chamber which is sealed about the spout and vapor recovery apertures. A device is connected to the spout receiving device for responding to flow through the chamber about the vapor recovery apertures. With this arrangement the volume of air recovered can be determined and compared with the volume of liquid dispensed to indicate the efficiency of the vapor recovery system.
