REMARKS
TESTING (Cont)
CAUTION
Do not permit the pressure in the test fixture to equal or exceed the capacity of the
pressure gage.
(4) Use the adjusting screw in
the injector tester handle
and depress the injector
plunger just far enough to
close both ports in the
injector bushing. The
point at which both ports
are closed is easily
noticed because the
injector spray will
decrease appreciably and
the pressure will rise.
