01 expedition intake manifold question

[evelknebel]

I bought the replacement dorman intake manifold and it doesn't have the vacuum port on the back of the plenum like the original manifold on the motor. Did they send me the wrong manifold? Is that vacuum line necessary or can I do without it. Any help or a link to a thread that explains this would be greatly appreciated. I have the 5.4L.

If your referring to the pcv bung then yes do. That is if you plan to retain pcv valve.
