200 m carb

[canadiandevil2]

Ok I have a 200m and i have a problem. i dont know what line goes on my gas tank from my carb there is a line coming from the top of the carb and one from the side. so which one should go to my on/off switch on my tank

The biggest line goes to the tank, it is on top. The smaller line on the side is an overflow. There is only one hose attachment that is the same size the one on the tank.
