New to 4 wheelers. Rode 4 wheeler around, after I stored in garage. It made whole house smell of gas. I went and checked it and it was leaking from a line on the left side where the oil stick was. I turned the gas from on to off and that stopped the leak.

However, I have never turned the gas off before and it never leaked. I looked around and it looked like that line in addition to another line which looked like a breather hose possibly were left hanging in a clip not plugged into anything. I looked around, but it does not appear to plug in anywhere. All though they can plug into each other.

Is that just a overflow line from the carb ? If so why did it leak gas last night and never before? I am new to all this if you can’t tell. Picture is below
