Excavator Fuel Water Separator – Complete Product Details Table

Item	Details
Product Name	Excavator Fuel Water Separator Assembly (Diesel Filter + Sediment Bowl + Base)
Compatible Models	Universal for Sany, XCMG, Komatsu, CAT, Hitachi, Kobelco, Doosan, Hyundai, LiuGong, Longong and other brands of excavators
Core Functions	1. Efficiently separates water, impurities and gum from diesel fuel 2. Filters fuel contaminants to protect precision parts such as high-pressure fuel pumps and injectors 3. Precipitates accumulated water, prevents fuel emulsification and icing, ensuring stable engine operation
Working Principle	Separates water and diesel by gravity based on density difference. Water accumulates at the bottom, impurities are trapped by the filter element, and clean fuel is supplied to the engine for combustion.
Usage Instructions	1. Check water accumulation in the sediment bowl before daily operation; open the bottom drain valve to drain water until no turbid liquid flows out 2. Tighten the valve after draining to prevent air from entering the fuel system and causing stalling 3. Pay attention to the direction of inlet and outlet ports during installation; ensure the sealing ring is properly installed to avoid oil leakage
Maintenance Interval	1. Drain water: Check and drain before daily operation 2. Filter replacement: Replace every 250–500 hours under normal working conditions 3. Shorten replacement cycle under harsh working conditions or with low-quality diesel
Product Advantages	1. High filtration precision and excellent water-fuel separation effect 2. Thickened shell, high pressure resistance and not easy to break 3. Translucent / transparent bowl for clear visual inspection of water accumulation 4. Easy drainage and maintenance, extending engine service life
Common Fault Symptoms	1. Insufficient engine power and unstable idle speed 2. Difficult starting and easy stalling during operation 3. Injector wear, increased fuel consumption and black smoke
Application Scenarios	Diesel engine fuel systems of various excavators used in earthwork engineering, mining operations, municipal construction, agricultural operations, etc.
