heavy duty truck fuel fine filter cartridge

1007781448 Fuel Filter Paper Core PU10031X 1007781448 fuel fine filter paper core is a genuine OEM standard filter element matched with cross reference part PU10031X, specially engineered for Weichai WP14 Euro 6 high-power diesel engines including WP14T 610HP power units. This multi-layer composite pleated filter media efficiently intercepts metal rust, sediment, micro abrasive particles and colloidal contaminants mixed in diesel fuel, delivering stable high-precision filtration under long-distance heavy-load transportation and off-road harsh working conditions. It fully safeguards high-pressure fuel injectors, fuel pumps and engine combustion chambers, effectively avoiding injector clogging, engine power attenuation, unstable fuel combustion and increased fuel consumption. Manufactured strictly following original factory dimensional standards and certified with IATF16949 quality system, this filter paper core maintains consistent fuel flow and long service mileage, serving as a cost-effective maintenance spare part for Sinotruk Sitrak heavy trucks and Weichai-powered logistics fleets to cut down engine breakdown risks and overall vehicle maintenance costs.  Product Material Description: This 1007781448 filter paper core adopts imported composite cellulose blended with ultra-fine glass fiber as the primary filtering medium. The filter paper undergoes professional diesel-resistant and anti-swelling resin impregnation treatment to prevent fiber shedding, hydrolysis and deformation after long-term contact with high-flow diesel fuel. It is equipped with rigid reinforced plastic upper and lower end caps and integrated internal support skeleton, which effectively prevents pleat collapse under fluctuating fuel pressure. The matched sealing accessory is high-elastic NBR nitrile rubber O-ring, featuring outstanding aging resistance, oil corrosion resistance and wide temperature adaptability. All raw materials comply with heavy-duty vehicle filtration standards, with uniform fiber distribution, balanced fuel permeability and extra-large dirt holding capacity.
