One other trick if you're trying to get air out of the system (Seastar, but should be the same):
Once you get everything squared away (filled, bled, whatever else you're doing to it), Put the fill cap on, turn the wheel to full lock one direction, then crank on it and turn it a bit more (you want to open the spring-loaded overpressure relief valve.) Then whip the wheel off and back onto lock several times (a half a turn or what's comfortable, about a half dozen times.) Give it a few seconds, then turn to the other end of travel and repeat.
When I replaced my steering fluid, I got probably another 30cc or so of air out of the system by doing this.
