A venting system for a fuel tank may include a first vent valve having an inlet, an outlet through which fuel vapor may be vented from the fuel tank, and a valve. The first vent valve may be located within a first chamber of the fuel tank. A second vent valve may have an inlet, an outlet through which fuel vapor may be vented from the fuel tank, and a valve. The second vent valve may be located within a second chamber of the fuel tank that is separate from the first chamber during at least certain fuel levels within the fuel tank. The support may carry both the first and second vent valves within the fuel tank and be movably carried within the fuel tank to vary the height of the first and second valves within the fuel tank as the support moves relative to the fuel tank. |
