A method and system for detecting leaks in a fuel dispenser is operative to pneumatically pressurize a selectable one of a vapor recovery portion and a fuel dispensing portion using a compressed air flow. A flowmeter measures the flow rate of the compressed air communicated to the fuel dispenser for pressurization thereof. A processor provides an indication of the leakage condition of the fuel dispenser based upon the pneumatic flow rate measured by the flowmeter which satisfies a pressurization condition for the fuel dispenser, such as maintaining the pressurization level above a threshold value. The flow rate of compressed air needed to maintain this pressurization level is indicative of the leak rate.
