PUMP PRESSURIZATION
Whenever doing any type of repair on jet pump, a
pressure test should be done to check for leak-
age.

After complete rebuilding of the jet
pump, oil MUST be added to the housing
BEFORE performing the pressure test in order to
seat the new seal, otherwise it will leak.
Proceed as follows
:
– Remove drain plug from housing cover.
– Apply Loctite PST 592 on threads of fitting tool
(P / N 295 000 086) then secure on cover.
– Connect pump gauge tester (P / N 295 000 083)
to fitting.
