Bleeding Saginaw Power Steering Pump

I would be tempted to do what dicer said and remove belt, put gearbox pressure side in a bucket and spin over by hand? I wouldn't wanna turn it over with engine...high psi there.
Well, I'm out of ideas so I'll give it a try....
What if I can't get fluid to come out....also if fluid does come out - what does that tell me?
