80 Suzuki GS550 Carb help. missing hose?

Howdy. I just picked up an 80 GS550L. I took off the carbs to clean them. I just bought the bike and know nothing about it. It no longer has the air box on it has little k&Ns for each carb. With the carbs off I realized that there are two tubes that don't have a hose connected to them. Does anybody know what they are? Should I block them off? Also the tube coming out of the fuel tank at the part with the wires(I believe it is the fuel sender) doesnt have a hose on it maybe they are connected? I think I noticed fuel coming from them when I was futsing around with the carbs but I could be wrong. I have included a picture to show the tubes. My manual was no help. Maybe there is a Suzuki guru who can help me out.

Just put the normal jargin in front of these 3 addresses. It wont let me post urls until i get my post count up.

They could be vents for the float bowls if there aren't vent hoses on the float bowls. Also another thing they could be is part of a PCV system that got ditched with the airbox. If thats the case then I would block them off.

I'm not exactly sure.Sorry. These guys might be able to help you.

I'm bored, what can I say? Now I got to go to work.





It says that they are a vent. Here are pics of the rest of the carb goodies.

Its for an 850 but your carbs look almost identical to the 850 carbs.
