Ricardo told us not to but we insisted on fitting a new power steering pump, just to reset the clock on what was rapidly becoming a "new" 5.0. That meant pulling the taper fit pulley off the old PS pump, which Ricardo is getting ready to do here. We should have listened, as the new pump is way louder than the old one we removed! "Typical!" said Ricardo. Stick with your existing pump if it's quiet and doesn't leak. Rebuilding your stock pump is a good option as well.
