A fuel filter water separator works by exploiting the density difference between fuel and water, allowing the heavier water to separate and collect at the bottom.
Here's a breakdown of the process:
- Density Difference: The core principle is that water is denser than fuel. According to the reference, because water weighs more than fuel, it sinks to the bottom of the filter.
- Separation: As the fuel-water mixture enters the separator, gravity causes the water to settle at the bottom.
- Collection: The water accumulates in a collection bowl or reservoir at the bottom of the separator.
- Fuel Flow: The fuel, being lighter, rises to the top and continues through the filter to the engine. Thus, the fuel runs on top of the water, as explained in the reference.
