Yet another vacuum tubes thread
So I have a Haynes manual for this truck, but to say it lacks critical information would be a <sarcasm>bit</sarcasm> of an understatement. Their lack of critical information is just sad. The Autozone (even though I don't shop there) website has more information than this book. This was an old farm truck that hasn't seen a road in 5 years. There are open and plugged vacuum lines all over the place. One of the big problems with diagrams is that they don't really show where the lines really go. No pictures of actual components. The diagrams show one line coming off a component, but the actual component has 4 lines coming off of it. Diagrams and real life sometime don't match up. Does anyone have a decent showing of all the vacuum lines on a 351? Pictures and routing would earn a gold star. Not real gold obviously, since the price of gold is ridiculously overpriced. Maybe a sheet medal star painted gold.
Thanks,

Ooops, a few more details.
1989 F250 with automatic tranny. Also found a bracket today right behind the throttle controls that sits on top of the intake manifold. The shape indicates that it is specialized for a specific component, but no component and no obvious wiring harness. Any ideas?

A photo would help of the bracket.
Is there not a vacuum diagram under the hood or on the radiator support?
Sounds like the bracket may be for the EGR, AIRD & AIRB solenoids.
Is the A.I.R. pump missing also?

The VECI is gone, so no help there. The bracket I'm seeing is covered up by your throttle cover. All the sensors seem to be intact, but I haven't fired up the multi-meter to go through and check them all. The smog pump is there, but it's not connected to anything, so I'm going to have to run lines back to the cat (eventually). I will post pictures ASAP. Things are kinda crazy right crazy right now. Living in the boonies with no car sucks. Thanks for the picture, it helped reassure about some of the sensors.
