Ever wondered why you have only ~14500 lb internal fuel instead of 16000 lb ?   Theres a bug/typo in the data (NA F-14A and F-14A_77 and the DLC F-14A_Iran) which prevents the RIghtFeedFuelCell from being used!   F14A_data
F-14A_77_data
F-14A_Iran_data   way down by the // Fuel Tanks --- sections

[RightFeedFuelCells]   <<-- BUG 
should read
[RightFeedFuelCell]


So delete that §("$&(!!?$$"  S ....
