I did this recently after replacing the PS pump on my '87 LeSabre... I ran the return line into an empty windshield washer fluid jug, plugged the inlet on the reservoir, and turned the pulley by hand. It took a bit of time and effort, but I am OCD enough to not want to actually RUN the pump with the gunky fluid in it.
I would recommend another flush when you do your next oil change, as some residual gunk will work its way through after the first flush. Also, I would recommend putting an inline power steering filter on the return line to catch anything that gets through after the second flush. An ounce of prevention, as it were.

I did the turkey baster method recently and used the GM cold climate power steering fluid and it really smoothed things out. (Last summer I had completely flushed the system with all new Lucas power steering fluid with a few ounces of Lucas stop leak.) That helped a lot with the low speed hard steering but the steering was still a little stiff during the winter. I did not want to open everything back up so I decided to try the turkey baster method. I had a math teacher friend figure out the dilution ratio so that I could estimate how much fluid was replaced. I changed out about 60-70ish percent. The steering is buttah smooth now and hopefully will keep the seals happy and be smooth during the winter. So far so good.
glad it worked out for you.
i need to pump out my new pump as well just bought it from aurtozone and it is making WAY too much noise. hoping some trans fluid instead of autozone fluid will help
if that fails I might try the lube guard stuff
always seen it but I have never tried it
