Deutz engine fuel fine filter 2000421

2000421 Fuel Filter Paper Core Cross 1117050-A635  2000421 is an OEM precision fuel fine filter paper core, cross interchangeable with part number 1117050-A635, specially designed for FAW Jiefang light & medium trucks equipped with Dachai Deutz CA4DD1 series diesel engines. As the secondary precision fine filtration core of the high-pressure common rail fuel system, this pleated paper core adopts gradient-density composite filter paper technology, which can efficiently trap fine silt, metal wear debris, carbon sludge and tiny residual water droplets after primary water separation. It provides ultimate protection for high-pressure fuel pumps and precision injectors, effectively avoiding internal clogging, abrasive wear and electrochemical corrosion of core fuel system components.Manufactured strictly in accordance with original OEM dimension standards and IATF16949 automotive quality certification, this paper core maintains stable fuel rail pressure, realizes complete diesel combustion, improves engine power output, reduces fuel consumption and exhaust emissions for daily urban logistics and short-distance transportation. Widely matched for Jiefang J6F, TigerV series light commercial vehicles. Every core passes strict pressure resistance, filtration efficiency and aging durability tests. We offer abundant spot stock, neutral export packaging & private label customization and a 12-month quality warranty, which is a cost-effective replacement spare part for global light truck parts wholesalers, auto repair shops and urban logistics fleet maintenance teams.  Product Material Description: Filter Paper Core: Imported multi-layer high-density wood pulp composite filter paper, with uniform dense pleats, stable micron precision, excellent hydrophobic performance, large dirt holding capacity and strong compression resistance to withstand long-term continuous fuel pressure. End Reinforced Plastic Frame: High-strength PA66 reinforced plastic upper & lower end caps, integrated molding technology, firm structure that resists deformation under fluctuating fuel pressure. Central Support Skeleton: Rigid molded plastic inner tube, firmly supports the pleated filter paper to prevent collapse and distortion caused by instantaneous fuel flow impact. Sealing Matching Structure: Precision end sealing structure, fully fits the original filter housing to prevent unfiltered fuel bypass.
