ok, there are two small lines one on top of the other. what goes on these lines? they look like they might be vacuum lines or something. as for the location of these two lines i think they face straight back towards the firewall when the intake is on the car.
back of the intake, 2 small lines and 1 big one, big one goes to the vacuum tree, 1 small one goes to the fuel press regulator, and the other small one?? I forget, maybe the heat/cool system, just trace them to see where they go.
