Can anyone help me identify what hose this connection is for? I saw that it was not connected to anything and was tucked away under the upper intake. It is located in front of the throttle body near the oil filler cap. I looked at the vacuum hose diagram but still haven't been able to figure out what its for. Not sure if came loose or broke off. Any help would be greatly appreciated.

 

Does that go to the aluminum check valve?

It kind of looks like one that goes to the front of the upper intake manifold. There are some nipples there that are short and 2 long ones.

I want to say that one or two of those nipples mentioned aren’t easily seen with the UIM in place without using a mirror.

 

Thank you Dale and Sgtblue for responding! I will try to look closer to see if a nipple is missing a hose on the intake. Mirror is a good idea!
