Re: 1994 Volvo 850 Vacuum Tree Issue
Fixed! One was leading to the cruise control pump, which needed to be left unplugged and the other went to the vacuum tree and was the boost gauge line. Cheers!

Re: 1994 Volvo 850 Vacuum Tree Issue
The cruise control pump has two vacuum outlets. Supposedly one goes to the cabin and the other is left open. Not sure why but that seems to be what I could find.
