Description
This premium heavy-duty diesel fuel filter is engineered as a fully interchangeable OEM replacement component, compatible with multiple cross reference part numbers: P550529, BF7814, FF5507, 33721, 20976003, 20972293, 22480372, BF7943, LFF8059, P550739. Manufactured under strict ISO quality standards and original equipment dimensional specifications, it requires no cutting or modification for direct spin-on installation, ensuring perfect sealing performance and stable fuel system operation under extreme working conditions.
Adopting multi-layer high-density hydrophobic composite filter paper, this fuel filter delivers outstanding filtration accuracy and excellent water separation capability. It efficiently captures metal rust, tank sediment, carbon fine particles and other solid contaminants in diesel, meanwhile removing condensed moisture and free water inside the fuel circuit. It comprehensively protects fuel injectors, injection pumps and the entire fuel supply system from clogging, abrasion and corrosion, stabilizes engine combustion efficiency, reduces fuel consumption and maintenance frequency, and significantly extends the service life of diesel engines and related spare parts.
