Trying to find out what a certain part is and where the vacuum lines from/to it should go. It's on the right rear of the intake as looking from the front. Roughly an inch in diameter with what I think should be 3 lines coming off of it? Every vacuum diagram I've seen doesn't label this device!!?? 1994 22RE thanks!!!

 

is it black? all 22re's typically have a ganged vacuum port piece that screws into the plenum back there, it has three ports.

can you post a pic.

 

Yep, I think your describing the one! I'll try to take some pics tonight... I currently have one tube hooked up and the other two ports off of it are broke off.

 

OSV, so my next question, since I believe your describing the right piece, what is the name it, what does it do, and where do the other two hoses route to if I can get a new one?

 

Also dumb question here perhaps....how do I take a pic and then draw on it to show questions, like I see many pics on this site are drawn on??

 

you can copy the pic to your computer, and draw on it with something like Microsoft paint, which should be located in the accessories folder on your pc.

is this it, where the red hose plugs into the manifold:

it's just a junction to share vacuum.

 

Yes that's it OSV!! I have a vacuum line that's plugged with a bolt, so I'm guessing that's not kosher? Your diagram shows the orange and red lines going to this device. Mine has only one currently connected, it goes to either the vsv or another device top/center of the head. I'm thinking the two ports that are broke off this thing need a connection. I tried to post pics I took, but can't seem to get that to work!

 

if they are leaking vacuum they definitely need attention.

i'd suggest googleing something like "1990 22re vacuum diagram", or whatever your year of truck is, to see what is plugged in where... a lot of people only have one of those ports plugged in... I use two of 'em.

there should also be a vacuum diagram under the hood.
