Isolator for leak detector tester
First Claim
1. Apparatus for isolating a leak detector mounted in a seat of a housing at a fuel storage tank and in fluid communication with and intermediate to the outflow of fuel from a submerged pump and a delivery line to a fuel dispenser, said apparatus comprising in combination:
- a) an isolator selectively mountable in the seat of the housing in place of the leak detector;
b) means for mounting the leak detector in said isolator;
c) means for interconnecting through said isolator the outflow from the submerged pump with an inlet to the mounted leak detector; and
d) a tap extending from said isolator for discharging fuel flow from the mounted leak detector.

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.
