I've had the tractor for a year, but today I noticed this hose moving some as I was using the machine. Not sure if the lower end of the hose should be connected to something or not. The hose I'm referring to is the one in the picture that I have folded over to make it more visible. It is connected somewhere at the top of the motor and comes down by the fuel filter. Should it be connected or does it just dangle loose? Thanks!
