ABSTRACT:
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 is installed between the submerged pump output line and the leak detector to make a field test of the integrity and operability of the leak detector.
