Not that it's a common problem, but in the event you get a split in a fuel line or primer bulb, carrying a cheap plastic pinch off clamp could save a huge headache to stop a spill into the bilge that would not only be a bear to clean up, but a safety concern as well. I picked one up when working on my snow blower and thought it would be a good item to keep in the boat.
