While doing my intake leak fix I broke the hard plastic line that goes from the fuel line to the passenger side of the intake manifold. I am not sure what this line is for......but I would imagine it has something to do with fuel since it comes out with the two fuel lines.

Anybody know the part number for this?

 

Not sure what the part number is but you can go to GM and they can look it up on computer. Just stand there and you can point out the line to them on the screen.

 

Where does it go on the passenger side, and where from the fuel lines does it come from.

 

Lets see if I can explain it....The three lines that come through up through the fender into the engine bay. Two lines goto the back of the fuel rail, and the other line goes to the front of the intake manifold and then turns into a hard plastic line that goes under the intake elbow and wraps around the passenger side of the intake manifold. I hook to the square box that is mounted on the passenger side. The box also has the hard line that goes to the throttle body connected to it.

It is hard to discribe, but hopefully somebody knows what I am talking about

 

It's the EVAP pipe.
