Fleetguard FF5838 equivalent filter

FF5838 Fuel Filter D368-002-903+A OEM Diesel Fuel Water Separator Filter The FF5838 fuel filter with OEM part number D368-002-903+A is a professional heavy-duty spin-on diesel fuel precision filter, cross-referenced with interchange part numbers including 088049EPS, S00031861+01, 5710993, FF42138 and FFP21501. Specially developed for Shangchai original electronic injection diesel engines, it acts as a vital core component of the complete vehicle fuel supply system. Its primary function is to thoroughly capture solid impurities, rust debris, colloidal sediments and free water contained in diesel fuel before the fuel enters delicate fuel injectors and high-pressure fuel pumps. Manufactured in full compliance with strict OEM industrial standards for commercial vehicles and engineering machinery, this filter is perfectly compatible with common rail diesel fuel systems. It delivers consistent and durable filtration performance under extreme harsh working conditions, including heavy continuous loads, high ambient temperatures, dusty surroundings, high humidity and frigid low-temperature environments. It is a premium aftermarket direct replacement filter widely applied to medium and heavy-duty trucks, engineering construction equipment and stationary industrial diesel generator sets worldwide.  Product Material Description: Outer Shell Housing: Constructed from thick high-strength cold-rolled carbon steel finished with anti-rust electrophoretic paint coating. The housing boasts outstanding pressure resistance and deformation resistance, along with superb corrosion resistance against diesel fluid, weak acid and alkali solutions. It can sustain regular fuel system operating pressure steadily without expansion, cracking or oil leakage, offering full physical protection for the internal filter element assembly. Internal Filter Media: Multi-layer composite high-density gradient wood pulp filter paper treated with hydrophobic resin coating. Designed with dense deep pleats to expand the effective filtration area to the maximum extent, it achieves integrated performance of fine solid particle filtration and efficient water separation. Sealing Components: High-temperature resistant nitrile rubber (NBR) gaskets and sealing rings. They resist long-term erosion by diesel fuel, retaining tight sealing elasticity within the working temperature range of -30℃ to 120℃, which effectively prevents fuel leakage and bypass of unfiltered raw fuel. Central Thread Base: Precision CNC machined solid carbon steel base with standard 1-14UNF-2B internal thread, featuring rigid structural strength for easy spin-on installation and convenient routine disassembly during maintenance.
