The hydroboost system only moves oil through the lines if the steering wheel is being turned, or during braking. Alot of fluid is used especially for braking. It is a two man operation, one to keep a steady eye on the reservoir level, and one to turn the wheel and operate the brakes. Alot easier to do when the frontend is off the ground.

You should add to the instructions that you will want some kind of wind barrier for the fan for dummies like me who don't want to end up wearing alot of the ATF. :P Luckily my girlfriend was on steering wheel and brake pedal duty or else I might be sleeping on the couch for a week.
