Kubota 12581-43012 Fuel Filter Assembly

The Kubota 12581-43012 is an inline fuel filter designed to protect the fuel injection system by removing particulate contaminants from diesel fuel. It utilizes a cellulose filter media element housed in a durable plastic or metal canister with 5/16 inch (8mm) barb fittings for direct installation into the fuel line. This filter serves as a direct replacement for Kubota OEM part numbers 12581-43010, 12691-43010, 13351-43010, 11420-43012, 11460-43012, and 1J456-43012. It is engineered for compatibility with Kubota V3300, V3800, and V2403 engine series commonly found in BX series sub-compact tractors, RTV utility vehicles, and select zero-turn mowers. Regular replacement intervals per the engine manufacturer's maintenance schedule are required to ensure optimal fuel flow and injection component longevity.
