Ok so i am doing the oh so fun Vacuum line replacement on my car when come to find out i have a bigger problem. if youu look at the picture there is alot of grease well thats from a broken oil injection line. My questions is the circled item in red, where does that go? does it need to be capped? this had nothing plugged into it when i took off the UIM.

 

That's your primary injector bleed. Source it to vacuum taken before the throttle plates, I use the middle nipple on the front of the UIM right where it meets the TB.

 

oh jesus god help me.
