Abstract
A filter assembly is configured to prevent water from infiltrating a fuel tank and/or engine. The filter assembly may include a housing having a fuel inlet line and a fuel outlet line. The housing defines an internal chamber in fluid communication with the fuel inlet line and the fuel outlet line. Fuel passes into the internal chamber through the fuel inlet, and filtered fuel passes out of the internal chamber to the fuel tank and/or the engine through the fuel outlet line. A filtering frame may be secured within the internal chamber, and may include a coalescing frame portion that is configured to allow water to coalesce thereon and sink toward a bottom of the internal chamber, and a hydrophobic frame portion that is configured to repel the water from a valve coupled to the fuel outlet line. A flow restrictor is configured to float on the water toward the valve. The flow restrictor sealingly engages the valve to prevent fluid from flowing through the valve when a surface level of the water is proximate to the valve.
