Post Need Vacuum Diagram 1988 f250 460

I bought truck not running I've got truck running now. Not very smooth vacuum hoses not connected and broken. Vacuum diagram on hood has been very little help. I'm fining hoses that are not showed on the hood diagram. I live in Oregon the truck came from Calf. So there's a lot of smog control on the truck that I'm not familiar with. Iím looking for vacuum diagram for Calf. F250 with 460 fuel injected engine. If anybody out there could email me. I want to get this truck running right. I'm a electronic guy worked in that field for 20 plus years. I got this truck not running was told it had a blown intake manifold. Found it did not timing was off vacuum hoses not hooked up exhaust pipes not tight fixed all these but vacuum hoses. I don't want to hook things up wrong already had enough friends do that. HA! They were trying to help. I'm here asking for your help so I can do it myself. If you can help please.

Thank you

The Vacuum diagram on hood is for the emission system show all the vacuum lines and should be used. That is the same diagram that I would post (email) for you if you gave the Calibration number off the door post.

There are other vacuum systems on the truck beside the emission one.
You also have the Vent system, brake booster, speed control systems hoses that are not on the emission diagram.

So I am not sure what you want, so what system do you want a diagram for?

vacuum diagram

Bill K, do you have diagrams for vacuum tube routing? I have an 88 f350, several lines are missing, gas mileage is worse than bad, truck wont start good when it's hot. I'm thinking somebody removed lines? Thank you, Kevin

Would need to know the engine size and the calibration number.
