How to Select a Fuel polishing System

  • Number one question to ask before selecting a fuel polishing system: What do replacement filters cost?

  • Number two question: Will this system clean fuel and remove water to engine manufacturer’s cleanliness specifications?

  • A well designed mobile system will have one micron disposable low cost filter to remove contaminates like rust, sludge, and bacteria clusters that could clog engine filters.

  • Always select a mobile system that has a clear water separator sight gauge that will show you water as it is being removed from the fuel.

  • The water separator should remove water from your fuel to less than 50 parts per million with a hydrophillic coalescer and hydrophobic water separator. Gravity separators are not recommended for flow rates over 10 GPM.

  • Always take a fuel sample from the tank bottom before and after fuel polishing.

  • Filter and water separator housings should be made from stainless steel or other acid resistant material; powder coated steel will chip and rust in time.

  • Be Safe!  Don’t use portable electric fuel polishers with gasoline or jet fuel. Electric cords and explosive vapors are not a good mix.

  • When choosing a system; keep in mind that 99% of the contaminates in a fuel storage tank, including water, are heavier than the fuel and will be found at the bottom 10% of the tank.

  • You won’t have to filter the entire contents of the tank unless the fuel has been disturbed or mixed. In that case it should settle to the tank bottom within 24 hours.

  • When working on diesel or gasoline storage tanks that have water contamination; high velocity pumps are not the answer. They will only cause more problems: diesel fuel will emulsify and not separate from the water, and ethanol blended gasoline will phase separate and become out of spec. with a low octane rating. It is best to use a polishing system with a low or variable velocity pump to separate the water from the fuel at a slow rate, then increase the velocity to remove particulate contaminants.
