On the basis on the tubing decal, the bicycle would appear to be from about 1976-1982. Based on the components, I would probably narrow it down to the latter half of that range.

Despite the derailleurs, you should be able to get enough date codes off the other components to get a reasonable idea which ones are original and what the model year was. Typically, Fuji used SunTour, Sugino and Dia-Compe for the major components during this era. A great resource for date coding is http://www.vintage-trek.com/component_dates.htm
