Vacuum hose routing/ diagram?

[Jeepwm69]

Got it. Thank you.

One last question, which end of the check valve goes towards the air cleaner? (guessing I can suck on the vacuum hose and see if it opens and stays open, but just want to be sure it's working ok).

I took the check valve off initially. Still have it though.

Thanks again for the help. The truck started running like crap and I found a broken rotted vacuum line. Spliced it back together and it ran better than it has in years. Then got industrious and decided to redo ALL the lines, and some of the multiple hose connectors were screwed up and not easy to figure out what hose went where when I was replacing hoses.
