My car is a rx7 fc vert 1990 and I have a hose that I can’t find where it goes to so I came to this place for enlightenment because I already pulled the throttle body to the upper intake manifold which is where it’s located and i could not figure out where it goes



The exposed silver tip is where I can’t figure out where the hose goes and the vacuum line diagram isn’t really much help that I can find

I will try to add a photo later to make it easier to see and distinguish it is by the back of the passengers side and close to the throttle cables

 

I think that vacuum tip is for automatic transmissions.

Are you talking about the vacuum nipple circled in red below?

 

I think it is but what should go there because mine is just raw

 

Mine is Manuel trans tho
