Bleeding Power Steering System
 

When I fixed my power steering system two weeks ago I filled it with power steering fluid before I later realized that I should have used automatic transmission fluid. My question is how should I bleed the power steering fluid out. I bled it once by loosening the small return hose below the resevoir and draining it into a cup but that was just for an emergency. I want to do this the right way since I've fixed my system. Any suggestions? I can drain the pump by removing the banjo bolt but the rack itself is another story.
