1117050-90D OEM Diesel Fuel Filter The 1117050-90D is a professional OEM-standard diesel fuel filter specially developed to match FAW Deutz CA4DD1 engines, which acts as a core filtration component in the vehicle common rail fuel supply system. This aftermarket replacement filter strictly follows original OE dimensional standards and production specifications, capable of efficiently capturing fine solid particles, rust, sediment, colloidal impurities and free water mixed in diesel fuel. It effectively prevents abrasive wear, corrosion and blockage of precision components including high-pressure fuel pumps and fuel injectors, greatly stabilizing fuel delivery pressure and improving full combustion efficiency of diesel. Designed for medium light commercial heavy trucks, this filter perfectly adapts to long-distance transportation, frequent start-stop and complex road working conditions, effectively lowering fuel consumption, reducing black smoke exhaust and engine failure rates. All finished products pass ISO 5011 professional filtration testing, with stable quality, sufficient stock for bulk wholesale, customizable packaging services, and a 12-month quality warranty, perfectly serving global auto parts distributors, repair workshops, logistics fleets and aftermarket maintenance users.
