How does a fuel filter work?

It works like a tea bag does. As the liquid fuel passes through, it stops any solid particles that may have gotten in, like rust or sediment from the gas tank or fuel lines.

It works similar to any other filter. A substance like air or a liquid is forced through a type of medium. Typically the medium is made of paper and in the case of a fuel filter cloth. The Medium has tiny little hole a specific sized design to only left fine particles through. This keeps debris out of the system.
