I can post a picture of my 87 R10, I have to check on the 91 R3500, but there isn't much on a V20, as far as vacuum. Just hoses going to the canister purge and to the MAP sensor. Post a pic of what you have/need.

There have been a bunch of discussions about vac lines and stuff. One link for the routing was from alldata website.
