1988 gulf stream 460 Ford motor vacuum lines
I am sorry if I am not posting this in the right forum. I have a 1988 gulf stream with the John Deere chassis and a Ford 460 motor. I need the diagram for the vacuum lines. Some are not connected ...

You may find that some of the vacuum-powered anti-smog devices have been removed, leaving the lines in place but not connected. We had an '85 Class C with that engine - what a disaster!
Since we don't have a requirement for smog testing every year, I unhooked quite a few of them to get the engine running better. We still only got about 6 mpg and that dropped to about 4.5 at altitude. Many of our trips were over the Cascades into Eastern WA and even with $2 gas, trips were expensive.
