The water pump cup is probably locked in there with corrosion but you could TRY this: Heat that aluminum housing up pretty toasty with a propane torch. You’ll need heat resistant gloves. Then quickly bang the housing down on a piece of heavy oak or the like, with the idea of the cup coming out from it’s own inertia. I do this all the time with bearing races and it works almost every time. I don’t know about a little water pump cup, though.

Long live American manufacturing!
