My grandsons ATV is having fuel running problems and I found a hose from under the choke that connects to nothing. He has broken numerous parts off the ATV and been able fix them but this hose has be stumped because I can’t see any purpose for it.

It appears to be a drain hose for the carburetor bowl. You can open up the drain and the fuel in the bowl will drain out the hose, and not all over the ATV.

Oh WOW thanks, I wondered about that but never seen that before. I'll have to figure out how to drain it because the boys siphoned gas out of an old lawnmower before it stopped running and it may just be bad gas.

Looks like the fuel shut off valve is in the off position
Yes I usually keep it in the off position when not in use.

I can't find any drain screw, but right now the tube is leaking and I have a container on the floor to catch all the fuel. I think the boys may have moved the choke too far cracking the diaphragm. The tank was full when this all happened and I'm having trouble pulling the fuel line off to drain it without it breaking. I may have to replace the whole carburetor at this point.

That looks like a Chinese made ATV. Usually, the fuel drain is a screw in the float bowl, as mentioned above. But sometimes, if there's no drain screw, and the carb is a common one used on scooters, the fuel drain screw is in the end of the hose.

Ok, that makes sense because it is a Chinese ATV and there is a spring clamp at the end of the hose which led me to believe the hose was connected to something in the first place. Now I think something fell off the end of the hose.
It did finally stop leaking and the tank is still full, but I don't know why it started to leak in the first place. It started to leak after I moved the choke handle down to allow room to pull off the fuel line to drain the tank.
