Does anyone have a link for a good vacuum/emissions routing diagram? the one on my rad support is gone/unreadable and the haynes book i have doesn't have a good diagram. trying to figure out what goes where as ive got lines unplugged, broken, cracked and even a few ports on the TBI that are just open. thanks for the help. its an 87 v20 w/350 by the way. thanks

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.
