What about boom refueling for a USAF F-14?
Assuming that you wanted to minimize the changes relative to the USN fuel system, the obvious location would be in the right side of the nose, just forward of the windscreen. This would minimize the extra changes to plumb the boom receptacle into the existing refueling plumbing. Done carefully, you might be able to retain probe and drogue capability. I have been pondering this with an eye toward USAF variants.
