2000102 WDK999/1 VG1540080310  VG1092080009  FF5737 FUEL Filter  This spin-on fuel filter is a universal heavy-duty aftermarket replacement element cross-referenced to multiple well-known OEM and international brand part numbers. It is professionally engineered for Weichai and Sinotruk heavy-duty common rail diesel engines, dedicated to fine filtration of diesel fuel to remove solid contaminants and free water. Manufactured under strict automotive-grade production standards, it features robust housing structure, premium composite filter media and reliable sealing performance. It can perfectly replace original filters for routine vehicle maintenance, effectively safeguarding expensive fuel injection assemblies, lowering breakdown risks and extending the overall service life of heavy-duty engine fuel systems under long-distance transportation and severe engineering working conditions. Filter Material & Filtration Performance: Advanced Composite Filter Media   Adopts multi-layer blended filter paper (cellulose + glass fiber synthetic media), with enlarged pleated filter area, strong dirt holding capacity, excellent resistance to diesel corrosion, high temperature resistance and low temperature stability, stable performance under harsh vehicle operating temperatures from -30℃ to 120℃. Precision Filtration Grade   Absolute filtration precision: 2μm, efficiently intercepts metal rust, sand, carbon deposits, colloids, fine solid particles in diesel fuel, and separates free water effectively. It perfectly protects high-pressure common rail pumps, fuel injectors and other precision vulnerable components of electronic injection systems. Flow & Pressure Performance   Optimized internal oil channel design matches original factory flow parameters perfectly, featuring low inlet-outlet pressure drop, stable fuel supply volume. No insufficient power or oil supply blockage during vehicle acceleration, climbing and heavy-load operation. Service Life Standard   Rated service mileage: 30,000 kilometers under normal highway working conditions, up to 20,000km for heavy-duty construction working conditions. Long-term stable filtration greatly extends the overhaul cycle of the common rail fuel system. Sealing & Shell Structure   Thickened cold-rolled steel shell with stamping forming technology; built-in high-performance nitrile rubber sealing ring, resistant to long-term fuel immersion. Zero oil leakage and structural deformation under normal fuel system working pressure, fully compliant with heavy truck high-pressure fuel supply requirements.
