Hitachi excavator accessory 1132008410 oil-water separator

1132008410 is a commonly used oil-water separator in Isuzu's original fuel system, also known as a fuel settling cup or diesel oil-water separator. Main functions: 1. Separate water and larger impurities in diesel through gravity precipitation and filtration. 2. Prevent water from entering the fuel injection pump and injector, avoiding corrosion, jamming, and early wear. 3. As the first line of protection for the fuel system, protect subsequent fine filters and high-pressure oil lines. Common fault manifestations: 1. Excessive water accumulation in the oil cup, water level alarm or unstable engine operation. 2. Blocked separator, poor fuel supply, resulting in difficulty starting or power reduction. 3. Aging seal, oil leakage, cup damage. 4. Failure of drainage valve, unable to drain water normally
