We have a 1999 6 x 4 Gator we purchased new, and now has 1329 hours on it. It has the two cylinder gas engine, and recently began to leak gas out of a short clear fuel line leading from the carb forward to a point between the engine and transmission. At idle a lot of gas pours from the end of the line, and at full throttle none leaks. Has anyone encountered this problem or have an idea what causes it?

Your engine may have a fuel pump mounted on top of one cylinder. If so, I would suspect the condition to be normal from your description. The fuel pump is driven by crankcase ventilation. At idle, the engine will receive a leaner air fuel ratio than at W.O.T/wide open throttle receiving a much richer mixture. Thus less fuel would be visible. Hope that helps you out.

Sorry, read the post wrong. The clear line is a vent tube for the carburetor. I'm thinking the float maybe sticking in the carburetor bowl. This would fill the carburetor bowl full t'ill it overflowed into the throttle bore. Does it run fine? Just fuel leaking out of the tube?
