On mine, I only see one hose. It is tied to the reservoir bracket, right behind the air cleaner and is, indeed, left open to atmosphere. I don't have that cap thing (Which I assume is a check-valve), or the second hose.

Still, I'm willing to take a guess: I suspect that is part of the evap system. When the engine is warm and under power, a solenoid opens up that sucks air across the charcoal canister and burns off leftover fuel. Most of that stuff is located on the bottom of the engine, if I understand the diagrams right. So, they'd want to run a vent hose up higher, so they don't end up sucking in water or something.

When it isn't midnight and freezing, I'll take a closer look for you.
