Help - 3.0 Fuel Tank Breather Valve Connects?

[pickncrew]

2004 X5 3.0i
My fuel tank breather (purge) valve is connected on one side with a hose going into the driver's fender well but I cannot for the life of me figure out where the other end goes. I just replaced the oil separator and hooking things back up but come to think of it I am not sure this end was hooked up to begin with. It's the piece that goes into the valve straight and from the diagram it almost looks like it goes to the throttle body (part on the lower left below) but there are no ports on the TB. Does anyone know??? Thanks...
