47-55.1 Pressure bleeding

I am going to say, Tuff Stuff likely does not make their own master cylinders. maybe they make their own prop valves, but masters are usually OTS (off the shelf) items because of the liability involved (and production needs! casting machining etc, thats a lot.). every GM master I have used the reservoir closest to the booster is the front output.
swap the lines. like ds says, nothing hard about switching the lines. might be magic.
