FS20258 Fleetguard fuel water separator

1125030-H02B0-SFG FS20258 OEM Fuel Water Separator Paper Core  1125030-H02B0-SFG is the upgraded long-life OEM inner paper filter core, cross-referenced to Fleetguard FS20258, specially matched for the original cannon fuel water separator assembly of Dongfeng Kinland Flagship heavy trucks with Cummins ISZ13 & ISZ15 Euro 5 / Euro 6 common rail diesel engines. It serves as the core precision secondary fine filtration component of the high-pressure common rail fuel system, adopting advanced coalescing composite filter paper technology. This pleated paper core can effectively capture fine silt, metal wear particles, carbon sludge, rust residue and emulsified micro water droplets after primary coarse filtration of diesel fuel. It delivers ultimate precision protection for high-pressure fuel pumps and precision injectors, effectively preventing internal clogging, abrasive wear and electrochemical corrosion of expensive fuel system core parts. Manufactured strictly in accordance with Dongfeng OEM dimensional standards and IATF16949 automotive quality certification, this upgraded 100,000km long-service filter stabilizes consistent fuel rail pressure, promotes complete diesel combustion, boosts engine power output, and reduces fuel consumption and exhaust emissions for long-distance heavy-load highway transportation. Widely compatible with Dongfeng Kinland KX, KL, KR flagship tractors, Tianlong series semi-trailers, heavy dump trucks and container logistics vehicles. Every finished paper core passes strict burst pressure resistance, water separation efficiency and long-term aging durability tests. We have abundant ready stock, support neutral export packaging & private label customization, and provide a 12-month quality warranty. It is a stable and cost-effective aftermarket spare part for global heavy truck parts wholesalers, professional repair service centers and large logistics fleet maintenance teams.  Product Material Description: Filter Paper Core: Imported multi-layer high-density gradient composite HV filter paper, with dense uniform olive-shaped pleats, stable micron filtration precision, excellent hydrophobic demulsification performance, ultra-large dirt holding capacity and outstanding compression resistance to withstand long-time continuous fuel pressure fluctuation, supporting 100,000 kilometers long service cycle. Matching NBR Sealing O-ring: Premium nitrile butadiene rubber gasket included, resistant to diesel corrosion, high temperature and low-temperature aging hardening, realizing full tight sealing to prevent unfiltered fuel bypass and fuel leakage completely. Top Reinforced PA66 Connector Cap: High-strength integrated injection molding plastic top connector, precise thread structure, firm rigid structure that resists deformation under fluctuating long-term fuel pressure impact. Internal Central Support Skeleton: Molded rigid plastic inner central tube, firmly supports the pleated paper core to prevent collapse and distortion caused by instantaneous peak fuel flow impact.
