FG1000 Fuel Water Separator Assembly High Flow 681LPH Diesel Filter For Heavy Duty Trucks

Product Overview​

The FG1000 fuel water separator assembly is a high-performance fuel purification component designed for heavy-duty diesel vehicles, construction machinery and commercial fleets. As a core part of the engine fuel system, it integrates precision filtration and water separation functions, effectively removing moisture (down to 5mg/L residual water content) and 2-30μm solid impurities from diesel fuel. Equipped with optional anti-freeze heater, water level detection kit and vacuum gauge, it solves common faults such as fuel system corrosion, injector wear and engine power loss caused by contaminated fuel. Widely compatible with Dongfeng, Cummins-equipped trucks and Parker-related engineering machinery, it ensures stable fuel supply under extreme working conditions.​

Core Product Advantages​

1. High-Efficiency Filtration & Separation: Adopts advanced composite filter media and gravity separation technology, achieving 99.9% water separation efficiency and trapping particles as small as 2μm, protecting injectors and fuel pumps from abrasion.​

2. Large Flow Rate & Low Pressure Drop: Maximum flow rate up to 681LPH (180GPH) with only 3.0kPa clean pressure drop, ensuring sufficient fuel supply for high-power diesel engines under full load.​

3. Extreme Temperature Adaptability: Operating temperature range of -40℃~+121℃, optional 12/24VDC heater automatically activates to prevent filter freezing in cold environments, while high-temperature resistant materials avoid deformation in hot conditions.​

4. Durable Structural Design: Aluminum alloy housing with anti-corrosion coating, resistant to diesel chemical erosion and mechanical impact; transparent water bowl with 305ml capacity allows visual monitoring of water accumulation.​

5. Integrated Safety Features: Optional water level sensor triggers alarm when water reaches threshold, preventing water from entering the engine; manual drain valve enables easy water discharge without disassembling the assembly.​

6. Wide Compatibility: Standard 7/8”-14 UNF (SAE J1926) port size, compatible with Racor 1000 series and interchangeable with filter elements 2020SM-OR (2μm), 2020TM-OR (10μm), 2020PM-OR (30μm).​

7. Easy Installation & Maintenance: Vertical/horizontal mounting flexibility, requires only 25.4cm upper clearance and 5.1cm lower clearance for servicing; modular design allows quick filter element replacement without professional tools.​
