dude, first, I love nipples. second, it's easy to miss being that it's hard to even feel being that it's kinda tucked in there. That's why I missed it cuz that rubber line that goes to it was pinched under the turbo inlet (when I still had it) and the stock fuel lines that run under the mani. I undid the tgv bolts a little and lifted up and started tugging on lines and sure enough, that line popped out and I felt like an idiot but I hooked it back up and the car turned on and purred
Moral of the story, make sure all nipples are getting a good sucking. lol
