Replaced engine. I cannot find the vaccum line that goes on the back of the intake manifold near throttle body. Where does thus line originate? And what is its function?

Good morning,

There are many lines. I need to know specifically which line.

Can you post some pictures for me? I need to see what you see to help.

That looks like the line that goes back to the fuel tank for the evaporative system.

Look for a loose line that goes back to the back of the car.
