I pulled my 351 out of my 88 f250 and i don't know how to put the vacuum system back together what lines go where. Also where the transmission modulator line from the c6 goes to. I could use pictures or what ever to figure this out thanks .

 

Did you check under the hood or on top of the front end of the engine bay? There's usually a sticker with a vac hose routing diagram on it.

Can't help you on the tranny line.

 

Digram for '89,



Modulator for C6 gets full engine vacuum, connect directly to intake manifold.

 

The diagram does me no good because I don't know what any of those things are. And does the tranny line connect to the
Vacuum tree thing on the intake.

 

Does anyone have a picture of the actual trucks engine and the vacuum lines that I can look off of for mine
