The FPR hose runs along the top the lower intake manifold (between the two sections) over to the airbox. That connection I believe goes from the throttle body to the intake manifold. But it's weird because that connection in your picture looks like a tee. Is it connected to that third smallest metal line on top of the manifold? What year is your runner?
Just realized I have the pics on my phone. These two photos should help. Sorry about the blur. I don't know where the other end of that hose goes, but maybe the pics can help you identify. Otherwise, I can look when I get home to see where other end of that one is connected if you have removed that one completely or something.
