Intake boot swap HELP

While replacing my intake boots I noticed two "T"s at the top of the carbs. Should there be a hose in between these connecting the left two to the right two? I believe it is Item 45 that connects to 42 on the parts diagram. The list shows I need 2 but I cannot tell where they connect to.

Thanks in adavance

Thanks for looking it appears they are vent tubes.

I wasn't sure what their function was, but FYI the hoses that come off the T are 1/4IDx3/8ODx25" I kinda thought they were overflows??

Yamaha parts diagram does not say much but the service manual shows them as a vent tube. I think the tubes are there just not hooked up. Looks like they run down behind the lower fairing. Does not seem right to vent a carb with out the air being filtered but I guess.

IF, the Float Valve, sticks, in open position, and the bowls flood, the fuel will run out these Overflow hoses,

I had this happen once, lots of fuel running down under the bike.

thats why the hoses are supposed to run down behind the engine !!

I think those hoses go to the air filter box openings, right at the D slot there is a a loop for them to go in. kinda like a vacuum for vapors.
