Well, I would assume (from my chronically limited knowledge of
aeronautics/aerodynamics - that's why I came here) that to add a tank of
sufficient capacity to have any decent effect on the range of the aircraft
would increase drag to such an extent that it would counter fuel economy to
the extent that it's presence would become academic.

Not sure though.
