PU1042 diesel filter element

801000-1105140 PU1042 OEM Diesel Fuel Water Separator Filter  801000-1105140 is an OEM standard precision fuel filter element cross-referenced with PU1042, specially designed for Yuchai YCK08 Euro 6 electronic common rail diesel engines installed on Dongfeng Chenglong H5 heavy trucks. As a core purification component of the modern high-pressure common rail fuel system, this filter adopts advanced coalescing filtration technology to efficiently capture rust particles, sand, sludge, carbon deposits and emulsified free water mixed in diesel fuel before fuel enters precision fuel injectors and high-pressure fuel pumps. It effectively prevents abrasive wear, blockage and electrochemical corrosion of delicate fuel system core components. Manufactured strictly in accordance with original OEM dimensional standards and IATF16949 automotive quality certification, this filter maintains stable fuel rail pressure, realizes full diesel combustion, improves engine power performance, reduces fuel consumption and exhaust emissions to fully meet Euro 6 emission standards. Widely applicable to Chenglong H5 logistics trucks, dump trucks, passenger coaches equipped with Yuchai K08 power units. Every finished product passes strict burst pressure, water separation efficiency and aging durability tests. We provide abundant spot stock, private label customized packaging and a 12-month quality warranty, which is a reliable cost-effective spare part for global commercial vehicle parts wholesalers, auto repair garages and large truck fleet maintenance teams.  Product Material Description: Filter Media: High-density multi-layer composite wood pulp filter paper with dense pleated structure, featuring stable filtration precision, outstanding water repellency, excellent demulsification ability and large dirt holding capacity for long-term heavy-load operation. Sealing Gasket: Premium NBR nitrile butadiene rubber seal ring, resistant to diesel corrosion, high temperature and low-temperature aging hardening, achieving full tight sealing to eliminate fuel leakage completely. Upper & Lower End Caps: High-strength reinforced engineering plastic end covers with integrated injection molding, rigid structure that resists deformation under continuous high fuel pressure impact. Internal Support Skeleton: Galvanized perforated plastic inner framework, firmly supports pleated filter paper to avoid collapse caused by instantaneous strong fuel flow pressure.
