Missing vacuum line. I think.

[Dechion]

Alrighty, as I am getting things working better on the old rust bucket I ran across what appears to be a missing vacuum line. :idea:

 

According to the vacuum diagram in Chiltons there are only 3 things connected to the vacuum mainfold, on my MJ there are five that I know for sure where they go, and one empty socket that needs to go somewhere. :???:

 

Problem is I can't find anything that is should be hooked up. :dunno:

 

Any help would be very appreciated.

 

here's a pic, as this thread would be kinda useless without it.

 

 

I could not get shots of the egr solonoid or valve, but they both have lines on them already. I Have a shot of the air cleaner, which has two lines going to it, and the vacuum regulator (I think) that has two going to it as well.

I'm pretty sure that goes to the back of the airbox. look to see if there is a spot for it to go and you got it. try napa for the vacuum hoses

Holy hell I'm a nub. :drool:

 

Found the vacuum line had been plugged into the wrong spot on the crossover unit by the PO. I had inputs on both ports on the bottom and on the top front, with outputs on both tops and the bottom rear. :hmm:

 

The top rear is supposed to be empty, but somehow the bottom front got plugged in there. (and looked like it belonged)

 

Why I did not see that at first I have no clue. :oops:

 

Thanks for the help folks, she runs much better with out having the vacuum system just kinda sucking air. :thumbsup:
