vacuum system diagram
looking for vacuum diagram or emission vacuum diagram for 85 GMC. the local chevy dealers don't have them as they are all on computer now. I just purchased it a couple of months ago and trying to get it all straightened out, I feel this is also why my cruise control does not work any help would be appreciated. I'm a brand new member so I hope I did this right:D

vacume lines
Just got a dealer repair manual the other day off of ebay. Let me see what I can do. There should be a decal under the hood showing vacume line routing. E mail me for a electrical schematic of the cruise,control system. I have a scanner.
