Fuel issues

[_Danoz_]

I have a 1990 Yamaha 350 Big Bear quad bike that has only had 2 owners and has seldom been used. Recently I noticed that the fuel line to the carburettor had come adrift. I replaced the hose and put a couple of clamps on it but fuel seems to be pissing out of a red tube that extends from the upper section of the carburettor forward over the engine.
I’m not overly mechanically miinded but was hoping that someone might have an idea what’s goin’ on?

Thanks in advance
