like, suction
me and my friend actually built a tool out of some lexan and an old piece of rubber sheet. I suppose plywood or anything fairly sturdy and flat can work, and even just a cork gasket material to seal it. Then had a ball valve hooked to a tube which we hooked onto a vacuum port on the intake that wasn't that vital looking and gradually did the normal bleeding procedure under a vacuum.
My mechanic friend found about that in auto shop at college while trying to diagnose a car that had been to several stealerships and replaced twice under warranty. A dusty old book way in the back had the answer and a picture of a tool (where we got the idea) and decided to give it a shot.
There's something about the Fords pump design or orientation that traps air where it just sort of doesn't really ever bleed out (hence the whine). And the vacuum helps suck it out since it's supposedly right where the fluid enters the pumping mechanism. But it worked brilliantly. And since we used Lexan we actually saw some air bubbles come out of the fluid.
I did a thing on it but I think it was on the old site... I'll have to give my friend a call and dig up that contraption again..
