Not a real expert on this. Was on a 1984 Black Max V6. Just found it.. forgot I had it. I think I removed it becasue of warning sensor on some shaft went bad. Sold boat. It is pretty complete. Not sure if anything is missing. $135 plus shipping from AZ. Tanks, shafts, pump, fittings, module and harness.....
I should have washed off the tanks.
