 2_ On the center tank rear spar, make sure the ACTUATOR-FUEL
 CROSSFEED VALVE (5QU) see/feel indicator is in the open
 position.

 (d) On panel 800VU, put the MODE SELECT SWITCH to the DEFUEL/XFR position.
 1 Make sure the OPEN light comes on.

 2 On the center tank rear spar, make sure the DEFUEL/XFR
_ ACTUATOR (11QU) see/feel indicator is in the open position.
 (e) On the panel 800VU, put the REFUEL VALVES switch for the RIGHT wing to the OPEN position.

 (f) On the panel 40VU, push (in) the L TK PUMPS P/BSWs. 1 Make sure the OFF legends go off, and the FAULT legends come

_ on momentarily.
 (7) On the FUEL page, make sure the left wing inner cell fuel content decreases and the right wing inner cell fuel content increases.
 NOTE : When an outer cell is full the incoming fuel passes through
____ the spill pipe into the inner cell.
 (8) On the panel 800VU, put the MODE SELECT SWITCH to the OFF position.

 (a) Make sure the OPEN light goes off.

 (b) On the center tank rear spar, make sure the DEFUEL/XFR ACTUATOR (11QU) see/feel indicator is in the closed position.

 (9) On the FUEL page, make sure the left wing inner cell fuel content and the right wing inner cell fuel content become stable and stay stable for twenty (20) minutes.

 (10) If the fuel continues to flow (leaks past the valve) when the DEFUEL/XFR valve is closed.
 (a) Do a check and replace if necessary: 1 The ACTUATOR-DEFUEL/XFR VALVE (11QU) (Ref. AMM TASK 28-25-53-
_ 000-001), and (Ref. AMM TASK 28-25-53-400-001).
 2 The DEFUEL/XFR VALVE (11QM) (Ref. AMM TASK 28-25-43-000-001),
_ and (Ref. AMM TASK 28-25-43-400-001).
 (11) Do the test given in step (6) through to step (9) again.

 (12) If no fault is found:

 - continue with the procedure which now tests the R refuel valve with left wing fuel pumps pressure.

 (13) On the panel 800VU, put the MODE SELECT SWITCH to DEFUEL/XFR position.

 (a) Make sure the OPEN light comes on.

 (b) On the center tank rear spar, make sure the DEFUEL/XFR ACTUATOR (11QU) see/feel indicator is in the open position.

 (14) On the FUEL page, make sure the left wing inner cell fuel content decreases and the right wing inner cell fuel content increases.

 (15) On the panel 800VU, put the REFUEL VALVES switch for the RIGHT wing to the NORMAL position.

 (16) On the FUEL page, make sure the left wing inner cell fuel content and the right wing inner cell fuel content become stable and stay stable for twenty (20) minutes.

 (17) If the fuel continues to flow (leaks past the valve) when the VALVE-REFUEL, R WING TK (8QU) is closed, do a check and replace if necessary:

 - the VALVE-REFUEL, R WING TK (8QU) (Ref. AMM TASK 28-25-51-000-001), and (Ref. AMM TASK 28-25-51-400-001).

 (18) If no fault is found:

 - continue with the procedure which now tests the C refuel valve with left wing fuel pumps pressure.

 (19) On the panel 800VU, put the REFUEL VALVES switch for the CENTER tank to the OPEN position.

 (20) On the FUEL page, make sure the left wing inner cell fuel content decreases and the center tank fuel content increases.

 (21) On the panel 800VU, put the REFUEL VALVES switch for the CENTER tank to the NORMAL position.

 (22) On the FUEL page, make sure the left wing inner cell fuel content and the center tank fuel content become stable and stay stable for twenty

 (20) minutes.

 (23) If the fuel continues to flow (leaks past the valve) when the VALVE-REFUEL, CTR TK (10QU) is closed, do a check and replace if necessary:

 - the VALVE-REFUEL, CTR TK (10QU) (Ref. AMM TASK 28-25-51-000-002), and (Ref. AMM TASK 28-25-51-400-002).
