Im putting my skunk2 intake manifold back on and i want to make sure that i dont **** anything up. There is a really skinny vacuum hose that im not sure where it goes, comes from fuel pressure regulator to intake manifold and im not sure if it goes on top of the intake manifold or on the back of it.

 

the hose from the FPR goes right to the nipple on the front of the IM.

 

i think there are also like two skinny ones that i believe are on the same clip as the FPR hose which attach to the back of the manifold... dont think it really matters which goes where because both are vacuum sources.
