Yes I'm running hydroboost for the booster and a GM MC. The hydroboost unit has three lines: High pressure in (comes from pump), high pressure out (goes to steering box), and low pressure return (goes back to pump). There is no vacuum in my braking system so maybe it's one of those lines you are seeing.
Depending on where in the thread you are looking I did run a small vacuum pump for tranny purposes that I mounted on the firewall under the brake unit but it wasn't part of my engine or brake system. I'm now running something else for tranny control. I did/do not have the steering/vacuum pump combo.
