I worked a job task card on 2 aircraft about 6 months ago. On page 2 step 5 it read; route the following wires per Figure 2 with 'SPECIAL ATTENTION' given to Figure 2 sheet 3 of 4; which provided unique wire bundle routing for the wire bundle W0054 due to Fuel Quantity Indicating Systems (FQIS) requirements. W0054 must be sleeved with connector ring and grommet from the upper a Reference Figure 2 sheet 2 of 4; to connector D46061 POS23; reference Figures 3; 4 and 5. The paperwork [had been modified to read]: To be sleeved from the upper Z Reference. So that would make the 2 planes I did had about a 1 1/2 foot of extra sleeving on it.
A Maintenance Technician reported that long after he worked a task card that had been updated with a change to the instructions he determined that the amount of protective sleeve that he used was incorrect.
