Two comments:
1. I never made such a claim. But nice try anyway.
2. If you're referencing the discussion of fuel having to move "uphill" due to dihedral and/or anhedral, the fuel system is not only designed to accommodate such features, but is designed to accommodate the worst possible unbalanced/uncoordinated bank condition (be it a slip or a skid) within the aircraft's performance envelope. Clu4U: aircraft are equipped with turn and slip/turn coordinator instruments for a reason. And if it has escaped you, the "uphill" condition created by a slip/skid far exceeds the "uphill" condition created by an/dihedral. And for the KC-10, the "uphill" condition of the tail engine far exceeds the "uphill" condition created by dihedral. Clear enough?
