Hi,

You can do better than I can since you can post up your own pictures.

That hose is short enough to connect to the flame trap screen holder that has a nipple sticking out to one side towards where that hose is pointing too.
It all hides just below the intake runners between the three and four cylinders.
It is down and to the left or the area rear of the engine.
It connects the horizontal hose from the side of accordion hose in front of the throttle body
