Narrative:

Fueling at self-serve pump with aircraft grounded according to manufacturer's specified grounding point. FAA inspector came over and said he was checking me because of 'interesting' grounding technique. I explained that this ground point (next to fuel port on top of wing) is the official grounding point as stated by manufacturer, in turn required by the FAA during us certification of airframe. Inspector continued to be puzzled by this after several repetitions of why the ground point is where it is. Inspector copied airmen certificate medical and aircraft information. I continued to finish fueling. Some fuel spilled on ground during tank sumping. Inspection could have been avoided if 1) non approved but 'accepted' grounding point used (wheels, exhaust, etc). 2) FAA inspector had more complete knowledge of aircraft type. 3) ground point officially moved to a more logical location.
