Moeller Three-Way Female Brass Fuel Valve, 1/4 in. NPT, Dual-Tank Selector, Part 033302-10

The Moeller 033302-10 is a three-way female brass fuel valve built to let a boat draw fuel from one of two permanent tanks at a time through a single line to the engine. It connects two permanent fuel tanks to one motor, with the valve position controlling which tank is feeding the engine, so you never draw from both tanks simultaneously. The valve body and ports are brass for corrosion resistance in a marine fuel system, and all three ports use 1/4 in. Female NPT threads for a direct threaded connection to standard 1/4 in. Fuel line fittings.

This valve meets ABYC H-24, the American Boat and Yacht Council standard covering gasoline fuel systems, so it is built to the dimensional and material expectations marine surveyors and installers check for. It is sold as a single unit and is intended as a manual fuel-source selector for dual-tank boats, replacing a worn or leaking three-way valve or adding tank-selection capability to a twin-tank fuel system.
