What are you planning on using for fluid on the PS? My Outback calls for Dexron V. I didn't see any in your pic, so I was curios.
As far as a method for the PS, someone on the SubaruOutback website mentioned a method where they used the turkey baster to drain the reservoir. Then the removed the drive belt from the ps pump, removed the return line from the bottom of the reservoir, and ran the return line into a waste container. Then turn the ps pump by hand until the fluid is all drained. Put the return line back on, fill the reservoir and turn the ps pump by hand until the system appears to be full. But the belt back on, take the car for a drive and make a few stop to stop turns, then top off the reservoir.
It seems that this method would be much more effective, and less expensive material wise, than the typical method of only draining the reservoir, driving for a few days, and repeating a couple times.
