The tube that goes down on the left side of the bike is the tank overflow drain. It shouldn't be connected to anything.
It should let the excess of gas off the bike if the tank is overfilled. It shouldn't let any gas out if the tank is filled properly, which is up to the neck.

How much gas do you have in the tank?
Is it letting go out all the gas?
Was the bike dropped?
Did you remove the left side fairing to see if there are broken parts?
Isn't there any hole in the tank?

The second hose should be a tank venting. I think the venting hose comes only in Californian models, and it should connect to the emissions control canister, also on the left side of the bike.

Sometimes it's tricky to see where the gas is coming from.
Even if those hoses were disconnected, the gas shouldn't come out of the tank unless the tank has a hole or there is a problem with the gas pump.
Clean up all the spilled gas and try again.
Make sure the gas is really pouring into the tank and not spilling out. Use another container if you don't trust that gas can without a nozzle.
