Extra hose?

So I took my carbs off to have a cleaning, and I put them back on and hooked what I thought was everything back up. Then I'm cleaning up my work bench and found an extra hose and I have no clue where it goes. It looks like the four that hook up to the bottom of each carb, just longer.



I can't for the life of me figure out what I'm missing because it looks like I have everything all hooked up.

I didn't think that year had pumpers, what carbs are those?

I would have thought that to be a tank overflow.

Do you have everything here?

So its probably one of the hoses for the #2 carb, I have no idea what else it could be. I thought I had everything set up like in Bluemeanie's pic, next good day I get off I'll head out there and check it out.
