I need help figuring out what vacuum line goes to this hook up. I just bought this car and heard a vacuum Leak and found this and I don't know where the rest of the line went that goes to it. The car is using a lot of fuel and has 0 torque at WOT. Hoping this fixes the problem.



This is the line I'm talking about. It is on the driver side. Right by the fuel rail. Where that 3-way valve is.





It is right below this.

What year and engine is this for?

Sorry I thought it showed from my profile. I'm new to this site. There is a metal line running under the fuel rail and this is a tee off on it. I found an old piece of hose sliced in 2 still attached to this and can't find the 2nd half of the hose. It is right by the 3 way hook up. The bottom leg of the tee actually attaches to one of the legs of the Y. The other leg of the Y is the one I can't figure out what attaches to it. Its circled in that pic. Sorry for the long post

I can't answer this for a 2.7t but you can search the forums or Google a vacuum diagram, should be a vac diagram sticker under the hood also.

Does the engine still have the combi valves and pump? I had to plug that line when I removed it.

Idk what those are. I plugged it and there was also a line plugged coming off the intake and I left that but the car still is using a lot of gas like 10 mpg and at WOT I have no torque. Plugging that line did give me more low end part throttle response and a little more power but my 0-60 takes 25.6 secs. Wtf could it be.
