Well after two monts of learning mechanics I am almost done with my 99 intake swap. Unfortunatelly as usual I am loosing determination and confidence to finish the project. All I have left is do vacuum lines which really confuse me as vacuum routing diagram on firewall is not helping much, junk yard doesn't have any 99+ 4.0 jeeps I can look at either. I did grab bunch of vacuum lines off a jeep at junkyard.
So far I have.
Fuel Injection rail has vacuum that goes somewhere to intake
Valve cover back line goes to the intake
valve cover front line can go to airbox
Also there are two lines on driver side. bigger ones goes to air box i think, smaller I have no clue but I think intake.
The intake has 3 vacuum ports on the side and 2 on the top. One of the top ones goes into brake booster.
I tried looking at other members swaps and pictures but its hard to tell.
It would help a lot if you just could tell me where the vacuum lines from side of intake go. There is three of them. Like I said one must go to fuel rail. 2nd to top of valve cover. 3rd either goes to driver side small vacuum line or the is another vacuum line long one that comes off firewall right by valve cover.
I even have difficult time explaing especially since I don't know the part and sensor names.
One more thing. Does it matter what size diameter and lenght the lines are or can I mix it up?
