Hey guys just got my carb cleaned, I took it off months ago and can't remember which is the clean air and which is the overflow. Can somebody help me?

also I know I need to put new hoses on these.

 

Top one with a 90 degree elbow attaches to the gas tank plug. It's part of the fuel tank overflow/vent system.

The Y-connector attaches at the three points to the petcock vacuum, carb. vacuum, and VOES. I forget which stretch connects to which, but they all should only reach to the right one so it should be apparent with a little moving around.
