Thanks for the help Mike. I got under the truck again and checked all the line from the hyrovac. There is nothing connected to it but one line that runs up to the DS fender with what looks like a filter. Whoever did the dual MC and booster still have the rear brake line coming from the MC to the hydro booster and then to the rear brakes. I think they only did this so they wouldnt have to mess with redoing the rear brake lines.
