Isuzu 8970818140 Fuel Sedimenter Water Separator Assembly

The Isuzu 8970818140 fuel sedimenter functions as a primary fuel water separator for 4JB1 diesel engines. It separates water and contaminants from diesel fuel before reaching the injection pump and injectors, preventing corrosion and injector failure. The assembly features a transparent sediment bowl for visual water level monitoring and a drain valve for periodic water removal. Designed as direct OEM replacement for Isuzu NKR55, NHR, NKR, 100P, and TFR series light-duty trucks. Constructed with aluminum alloy housing and polymer sediment bowl, the unit withstands diesel fuel exposure and engine compartment vibration. Mounting configuration matches original equipment specifications with identical port thread sizes and bracket positions. The separator element provides filtration efficiency meeting Isuzu engineering standards for 4JB1 engine fuel system protection.
