1117031-LPA20 truck fuel filter

1117031-LPA20 Heavy Duty Spin-On Diesel Fuel Filter The 1117031-LPA20 spin-on diesel fuel filter is a high-standard aftermarket replacement component manufactured strictly according to automotive industry specifications, specially designed for light and medium-duty diesel trucks, delivery vans, passenger buses and matched industrial diesel engines. During daily urban distribution and long-distance highway transportation, diesel fuel will inevitably mix with rust particles, sediment, sludge, fine metal shavings and dust generated in storage and refueling processes. If these contaminants flow into the fuel injection system, they will cause fuel injector clogging, accelerated fuel pump wear, difficult cold startup, unstable engine idling, insufficient acceleration power and rising fuel consumption. Adopting multi-layer gradient pleated composite filter media, this filter achieves high-precision solid impurity interception, continuously supplying clean diesel fuel to the engine fuel system. It effectively protects precision fuel system components, stabilizes engine power performance during long-time continuous operation, lowers the risk of sudden mechanical faults and cuts routine maintenance expenses. With stable filtration efficiency under high fuel pressure and variable temperature working conditions, this 1117031-LPA20 filter acts as a practical, cost-effective maintenance spare part for logistics fleets, auto repair workshops and small engineering equipment operators worldwide.  Product Material Description: Filter Media: High-density multi-layer composite fiber filter paper with uniform pore distribution, stable filtration precision and excellent dirt holding capacity; Outer Housing: Thickened high-strength cold rolled steel shell with electrophoretic anti-rust coating, resistant to diesel corrosion, external impact and outdoor scratch damage; Sealing Gasket: Premium nitrile rubber (NBR), featuring outstanding oil resistance, wide high-low temperature resistance and long anti-aging lifespan for complete leakproof sealing; Internal Reinforced Galvanized Metal Skeleton: Firmly supports the filter element to prevent deformation or collapse under sustained working fuel pressure; Precision Machined Thread Interface: Strictly consistent with OEM original thread size for seamless installation matching the original filter base.
