A device and method for testing for the recovery of vapor in a system in which a fluid is dispensed into a tank through a nozzle, according to which a vacuum is created to induce the flow of the vapor into the nozzle. The vacuum is measured and a display is provided that indicates whether or not the vacuum attains a predetermined threshold value.
