The pore size in the filter media determines micron rating. The percentage of dirt that a filter removes determines efficiency. Efficiency rating relates to the percentage of particles at a given size that a filter can capture i.e. 90% of particles 10 micron and larger in size. The higher the efficiency, the higher the

why 10 micron filtration @ over 90% efficiency? Once in the fuel injection system, 10 micron contaminants and larger can cause severe damage because of the close tolerances within fuel pumps and injectors. Clogged injectors and/or worn fuel pumps causes inadequate fuel delivery that can lead to poor fuel economy and engine performance.

Water is commonly found in fuel systems and can come from a variety of sources. Condensation, fuel handling and humid marine environments will increase the presence of water. Water contaminated fuel can lead to poor engine performance and even engine damage. Today’s ethanol blended fuels can increase the chance of water in the fuel tank. Fuel provides lubrication to the fuel injection system. Any water that displaces the fuel’s lubricating qualities can increase the chances of premature wear and component
