Or just remember to unplug it....... no sense in spending money on an unnecessary switch.

This is not true. There is still pressure on the fuel system. But with the motor off, the pump only runs for a set amount of time (about 15-20 sec) and then shuts off. A good fuel system should hold pressure for a few hours. But we are talking about Cub Cadets here, so no matter........

Nothing. The pump destrokes. Just like it does when the motor is at idle for long periods of time and not using much fuel. That said, it is still a good idea to kill power to it if the key is left on for long periods of time. (10-15 min or longer.) If nothing else it will run the battery dead quicker.
