    The working steps of the 1/4" oil-water separator in the car:
    1. After the fuel enters the filter separator, the solid impurities are first filtered out by the filter layer.
    2. In the demulsification layer, the oil and water in the emulsified state are separated.
    3. In the 1/4" oil-water separator, small water droplets will condense into large water droplets and be stored in the sump.
    4. Through the water repellent effect of the separated filter element, the small water droplets that do not condense are collected into the sedimentation tank, and then discharged from the drain valve.
    5. Finally, drain the fuel whose moisture has been separated from the 1/4" NPT air filter with regular trap.
