My NAPA store was able to order the correct fuel filter for my AC car a couple of years ago, had it in a day or two. You might also try
www.rock auto.com or USA Parts. USA parts is at 703-335-1935. USAs catalog lists them as part # 3.890A, $8.95 in their 2004 catalog which I have at hand. Dont know about the pump gears but again I would try NAPA, Rock Auto, Hemmings, or a local engine overhaul facility, a hot rod magazine, Egge machine, etc., etc.
