Are both of these left open?

I know one of them is left open and they are on the same rail so I'm guessing both are left open? On my 2005 I can see 1 is left hanging open (longer tube on my 05). I can't see them both due to the air intake so I gotta ask.

Aren't those the fuel vapor vents? If so, there should be a y piece bringing them together, then connected to one of the filter housings.

or 't' them together and stick end of a vacuum line on the 3rd leg of the t (or y) and put the loose end of that in someplace that has nice dead, non turbulent air (under fuel tank on top of frame rail works, as well as the extra nipple on the fuel sending unit's plastic cover). under the seat wont likely work (didnt for me)
