I posted this in the 2.5L SOHC section also, but didn't get a nibble, so will try it here as well:
Trying to resurrect a neglected 1998 Ranger 2.5L with 5 speed manual trans, I keep finding cracked and broken vacuum lines and splices. I know there's supposed to be a vacuum diagram on the radiator support, but it's been damaged, and is unreadable. Is there a complete vacuum diagram for a 1998 2.5L available anywhere? Thanks.

 

Have you tried to Google it?
That might be your best choice.
You might contact your local Ford dealer for a diagram or information.
Down here they are usually pretty nice about this kind of stuff.

This might help some.

Thanks, Ron, but the local Ford dealer suggested I buy a Ford shop tech manual for around $350. I might have found a facsimile of the original, will try it in the morning. Any way, the ol' guy will ride again!
