233-9856 Fuel Filter for CAT C4.4 Engine E308 Excavator
The 233-9856 fuel-water separator is primarily used in the fuel system of Cat E308 series excavator diesel engines. It pre-separates water and large impurities from the fuel, effectively reducing the risk of water entering the high-pressure fuel pump and injection system. This fuel-water separator offers excellent fuel-water separation efficiency and is suitable for the high-dust and high-humidity working conditions common in construction machinery, helping to extend the overall service life of the fuel system.
