4. Procedure
Subtask 28-28-00-440-050-A ** ON A/C NOT FOR ALL
A. Reactivation of the ACT Fuel Transfer Valve
NOTE: The subsequent procedure is the same for each installed ACT. Therefore only one procedure is given. Differences between each ACT are given where applicable.
   (1) Remove the T720521 TOOL-VALVE LOCKING from the flange of the ACT Fuel Transfer Valve.
   (2) Remove and discard the TIE WRAP(S) from the electrical harness, to release the electrical connectors (4) and (11).
   (3) Remove the CAP-BLANKING from each electrical connector and receptacle.
   (4) Make sure that all the electrical connections are clean and in the correct condition.
   (5) If the actuator (3) of the ACT Fuel Transfer Valve (1) is unserviceable, replace the ACT Transfer-Valve Actuator (Ref. AMM TASK 28-28-53-000-001) (Ref. AMM TASK 28-28-53-400-001).
   (6) If the ACT Fuel Transfer Valve (1) has a failure in the open position, replace the ACT Fuel Transfer Valve (Ref. AMM TASK 28-28-33-000-001) (Ref. AMM TASK 28-28-33-400-001).
   (7) If the fault continues:
