PU0919 fuel water separator

801000-1105350 Diesel Fuel Water Separator Paper Core The 801000-1105350 paper filter core is an OEM-standard Euro VI emission fuel water separator element specially developed for Yuchai National VI diesel engines, cross interchangeable with part number PU0919, perfectly matched for Dongfeng Liuqi Chenglong H5 heavy-duty trucks. Manufactured strictly under IATF 16949 automotive quality certification, this multi-layer hydrophobic pleated composite filter paper can efficiently trap rust sediment, metal particles, carbon residue and solid impurities in diesel fuel, while separating free water and emulsified moisture from fuel effectively. It provides full protection for high-pressure common rail fuel pumps and precision injectors, effectively preventing injector blockage, internal corrosion, insufficient power output and unstable engine operation caused by contaminated fuel. This filter maintains stable filtration performance under long-hour heavy-load transportation, continuous road vibration and drastic temperature fluctuations, adapting perfectly to long-distance logistics, construction sites and complex working conditions. Designed with precise original OEM dimensions for direct plug-and-play replacement without modification, it is widely favored by global auto parts wholesalers, truck repair workshops and fleet maintenance suppliers. It delivers stable filtration performance, long service mileage and excellent cost performance, which significantly reduces fuel system failure rates and cuts routine maintenance costs for commercial fleets.  Product Material Description: Filter Medium: High-density hydrophobic reinforced cellulose filter paper, outstanding water repellency, large dirt holding capacity and stable fuel permeability Inner & Outer Support Frame: Galvanized perforated steel mesh, pressure-resistant, anti-deformation and rust-proof against long-term diesel erosion Upper & Lower End Caps: High-strength reinforced engineering plastic with anti-aging coating, shock-resistant and firm structure Sealing Gasket: High-temperature nitrile rubber O-ring, aging-resistant and fully leakproof for long-term sealing Bonding Adhesive: High-performance industrial hot melt glue, tight permanent lamination, no degumming under vibration and temperature variation
