Hi all,
Starting to get things ready to put the car back together and found something I'm not sure about. There is a nipple on the top of the engine right where the filler next comes and attatches. Where does this hook up to? I looked and it is on my N/A motor and had a hose coming out that seemed like it would go to the UIM.....but I didn't see anywhere it would hook to unless it is vacuum (I was under the assumption it was oil, but I don't have a clue). Just trying to get my mind back in order so putting everything back goes as smoothly as possible. Thanks for the help in advance.

Crap, sorry, wrong section, if the mods can move to gen specific that would be great. Thanks.
