carbs and fuel line replace

[kmh154]

I have my carbs out to clean and going to replace fuel lines. Took a piece to the store to get new hose and cannot figure out where all the fuel lines connect back to. there seems to be two different sizes coming from the gas tank and only one bigger connection point on the carbs. I am guessing that is for the bigger sized line from the tank how bout the others. not the little ones though only the bigger lines. pics? On 99 XP limited
