Fuel polishing is a filtration process that removes water, microbial contamination and particulate matter from petroleum-based fuels. The fuel polishing system of Felix Marine Industries (FMI) is the Clarus 250 model. This is a patented, four-stage filter and polishing machine that effectively removes water and solid contaminants down to ½ micron in size. The variable speed pump draws contaminated fuel through a sock filter, and then pumps the fuel through a one-micron pre-filter. After the pre-filter, the fuel is pumped through a water coalescing and separating two-part filter. The fuel then passes through the final two polishing filters for additional filtering down to ½ micron and where any residual water is trapped, before returning the fuel to the tank in nearly new condition.

Are you concerned with the possibility of corrosion inside your fuel tank? Does the subject seem confusing? Well, you’re not alone, In fact, no one understands these conditions fully, but I hope to clarify some of the causes and identify some solutions.
Boaters can avoid leaks and increase the life of their fuel tanks, prevent costly repairs, and environmental accidents with proper maintenance.
The problems begin with the reality that in most pleasure boats the fuel tanks are a long-term storage facility. Today, diesel and bio-diesel products are inherently unstable and begin to break down within 90 days of delivery. Modern diesel fuel is produced differently from the days when companies relied on a more stable distillation process. Fuel oils are now catalytically cracked and rely on manipulation of hydrocarbons. The fuels delivered today are a blend of both processes.
