I got this 85 w150 project i'm starting. When I got it vacuum lines were hanging from transfer case. I got a book, but nowhere are their routing mentioned or pictured. It also looks like a round vacuum canister is fitted to frame down there. Can anyone help me with their routing? thanks

 

in case anyone else was wondering; the confusing vacuum line turned out to be the vent, supposed to hook to a filter & dangle. I was confounded because it followed the same path as the 1 going to manifold vacuum. The other 2 of coarse went to axle motor & reservoir. Turns out this diagram is only available in original service manual... who da thunk it!!!!!!!!!
