Moeller Disposable In-Line Fuel Filter, 5/16 in. Barb, 10 Micron Filtration

The Moeller Disposable In-Line Fuel Filter (033316-10) is a compact, single-use fuel filter designed to be installed directly into a 5/16 in. Fuel line using its 5/16 in. Barb fittings. It provides 10 micron filtration, trapping fine debris, dirt, and contaminants before they reach the carburetor or fuel injection system, helping protect engine components from premature wear and fuel system clogs. Because it is disposable, there is no cartridge to service or clean; when the filter reaches the end of its service life, the entire unit is simply cut out of the line and replaced with a new one, making maintenance fast and straightforward.

This filter is built for use in-line on small engine and marine fuel systems where a compact, economical filtration solution is needed. Its 5/16 in. Barbed connections are secured to the fuel line with standard hose clamps, and the low-profile housing fits easily into tight engine compartments. As a Moeller product, it is manufactured to be a reliable, drop-in solution for routine fuel filter replacement or new fuel line builds.
