Fuel polishing is the process of removing contamination such as

water and particles from fuel to ensure that it remains in line

with fuel specifications. Ideally, fuel should have an ISO particle

code of 18/16/13 and a dissolved water content no greater than 200

parts per million. There should be no free or emulsified water

present.

Fuel polishing will ensure that the fuel is 'clean and dry'

meaning free from water and dirt thereby reducing the possibility

of engine or fuel system damage.
