power steering pump seal blowing out....5 times now

yeah i did mean the box. 66 what did you do to fix it.......

i did replace it with a used one after my original steering box started to leak. it had a broken piece inside it so i scrapped it. the leak had nothing to do with the broken piece though. IF it is the wrong seal its very close. ten thousands more metal on the outer diameter and it would stay in there. I am at a loss......could it be the pump putting too much pressure to the box....ive never seen one do that before but i am reaching here....maybe the housing is bad
