A tester, temporarily connectable to a tap in the input line for a gasoline dispenser, tests the integrity of the delivery line from a submerged pump within a gasoline storage tank to the tap, including a leak detector, whether piston or diaphragm operated, normally mounted at the storage tank downstream of the submerged pump. An in line isolator can be installed between the submerged pump output line and the leak detector and connected to the tester to make a field test of the integrity and operability of the leak detector.
