Vacuum line
Does anybody know where the black vacuum line goes that’s hooked up to the back up the vaccum reservoir? I’ve googled and did my search but could not come up with anything! Thanks!

Make sure you post which truck you have.

He might be talking about the line for the 4x4 on the right side back, that doesn't go to anything. It lies open. Why? Never have figured that one out.

Well there's 2 reservoir's. One that's visible and attached to the battery box. The other is attached to the inner fender and out of sight. A picture and model year would help me get the connection pic right. Perhaps he'll post one later, -and more info.

Yea , the only one I've seen open is the diff breather personally. That attaches to the inner wheel well liner. But yea, I've heard the same thing from others that have another going nowhere a little further up...between the batt box and firewall. I've never seen a pic of that one, just heard about it lol.

I've seen one on my old neighbors 06 Expy. It was red in color, and it appeared to be broken. But, I found that it didn't need to go to anything.... may have been AK who helped me on that.

Might have been full time 4wd. Red goes many places...reservoir, 2wd/4wd solenoid and main vac.
