I am wondering what this nipple connects to since it isn't mentioned in any of the hose diagrams and I searched. It is located on the lower intake manifold in the top middle burried underneath the primary fuel rail and vacuum spider. The hose was brittle when I pulled it out and I broke it. I tried to back track to it's location with the broken preformed hose and I thought it might connect to the fuel pressure regulator nipple but that connection is mentioned in the vacuum diagram. Can anyone help me out real quick because I'm working on it right now

 

k just went out an checked. I'd wager it's one of the hoses that connects in the group of three at the uim. Can anyone confirm this? Is there any order the two of the same size need to be put on ie one on top other on bottom or is it the same pressure source?

 

1st, 2nd or third generation? They are all different.

Nipple stick straight up or at an angle towards the rear?
