Nope.
You just have the right breather hose connected to the intake just before the throttle body and a small vacuum hose connected from the engine block to the elbow leading into the intake manifold (I believe it's the connection next to the orange vacuum line in the picture).

If you look at the newly posted pix of the 40V breather hose setup, the vacuum hose was removed and the circular "horn" was added to the right side breather hose for vacuum.
