1. Install 0--4000 psi testing gauge assembly with
adapter in impact wrench pressure port
(smaller of quick--disconnects) in the
refuel/defuel stowage compartment.
2. Install 0--300 psi dial pressure gauge with
adapter in impact wrench return port (larger of
quick--disconnects) in the refuel/defuel stowage
compartment.
3. Place flow control valve to closed position and
set flow regulator to 0.5 setting.
4. Start APU (TM 9--2350--292--10) and place
system selector valve to fuel transfer position.
Record gauge readings.
5. Shut down APU (TM 9--2350--292--10).
If pressure port is not
1650--1750 psi go to Step E.
If return pressure is not less
than 75 psi go to Step F.

Are wrench, quick--disconnects, and connections free of
leaks, restriction, and damage?
no
yes
Check the impact wrench and quick--disconnects
and connections in stowage compartment for leaks,
restrictions, and damage.
Tighten leaking con-
nections and remove
restrictions. If restric-
tions cannot be re-
moved, or if part is
damaged, replace
(WP 0570 00). Verify
fault is corrected.
