Moeller 033305-10 Brass 3-Way Fuel Tank Click Valve, 1/4 in. NPT with Detent

The Moeller 033305-10 is a three-way brass fuel valve built to let boaters direct fuel flow between two tank sources, or shut fuel off entirely, from a single control point. Its brass body threads into 1/4 inch female NPT fuel line connections and includes a detent mechanism that holds the handle firmly in each selected position, so the valve will not drift out of position from engine vibration while underway. The design uses a click-valve action, giving a positive, audible confirmation each time the handle is moved to a new position, which helps confirm the valve has fully seated rather than stopping partway between settings.

Solid brass construction resists the corrosion that marine fuel systems are prone to from fuel exposure, humidity, and salt air, and the valve is built to the ABYC H-24 standard covering fuel system fittings. It is a compact, three-port unit intended to be plumbed into 1/4 inch NPT fuel lines wherever a boat's fuel system needs tank switching or a positive shutoff point.
