Spin-on Diesel Fuel Filter 1000422382 BY1000422382 612630080087 Weichai WP10 WP12 Engine
Diesel flows from the fuel tank, and the coarse filter (oil-water separator) first removes large particles of impurities and water, then enters the main filter element for precise filtration:
1. It intercepts fine dust, rust, and gel particles in the diesel;
2. Protects the high-pressure common rail injector and high-pressure oil pump (for engines of standards 4, 5, and 6, the injection pressure is extremely high, and fine impurities can easily wear out the nozzle);
Note: This model does not have a water cup and does not have an oil-water separation function; the oil-water separation is carried out by the previous oil-water separator.
