Please excuse my inability to understand.

I assume you clicked on the image (that is about as large as I could expand the image, without distortion).

I think the illustration shows a black rubber hose?

It looks like the hose has a clamp on one end - near/into the lid on the air cleaner?

It looks like the hose has a clamp on the other end - near/into the valve cover?

Do you see a hose that runs to the other side of the engine?
If so, does that hose go over the valve cover?
