Doosan 400508-00063 Fuel Water Separator Assembly

The 400508-00063 is a spin-on type fuel water separator designed for Doosan and Daewoo heavy equipment. It utilizes depth-type filter media with a circular pore structure and gradient filtration to intercept particulate contamination and separate water from diesel fuel. The housing features a standard thread interface for direct installation on the engine fuel system. It is engineered to meet OEM specifications for fit, sealing, and filtration performance under high-pressure common rail system requirements. Construction includes a corrosion-resistant housing, nitrile or fluorocarbon seals for fluid compatibility, and a drain valve for water evacuation. The element is rated for operating temperatures ranging from -20°C to 100°C. This filter protects precision fuel injectors and pumps from abrasive wear and corrosion, ensuring engine longevity and compliance with emission standards.
