Diesel Fuel Cleaning & Polishing at Harbor Marine Service

What causes fuel problems?
Long-term storage and water contamination are the primary causes of bad fuel. Even if you get dry clean fuel, your tank system is vented (unlike a car) and the vent will allow humidity to enter. Water also condenses on the tank walls due to temperature fluctuations. Microbes can thrive in this water. You can kill these bugs with a biocide, but you will still be left with both their carcasses and water which can clog your filters and eventually shut down your engine. 

What is diesel fuel polishing?
Fuel polishing removes all the water and resulting contamination (including bugs) from your tanks. We’ll bring our portable Reverso system to your boat (or wherever you have diesel fuel stored) where it will draw fuel from the bottom of the tank at approximately 1200 gallons per hour, purify it through the filtration process (spinning out water and sediments,) finally returning it to your tank as clean, usable fuel.

We also offer engine computer diagnostics, electronic engine diagnostics, and other marine products like bow thrusters.
