FAQs

Diesel fuel polishing is a process performed by pumping the fuel through a series of filters and oil/water separators to remove contaminants, such as water, bacteria, and sludge. It cleans and purifies the fuel so it will burn better and cleaner in your equipment. However, fuel polishing alone doesn’t clean the tank or restore stability, lubricity, and combustibility to the fuel. A full service fuel quality program is needed to accomplish that.

Engines need clean fuel to run reliably. Most engine failure is the result of contaminated fuel. Cleaning the tank is an effective way to prevent costly repairs.

It can be costly, but pumping out and disposing of contaminated fuel, as well as the replacement of corroded tanks, is far more expensive than fuel polishing, tank cleaning, and regularly scheduled maintenance.

Water vapor inside the tank and seepage past the fuel line are two sources of water contamination. The water accumulates and grows microorganisms that appear as sludge on the bottom and sides of the tank.

Anyone who stores diesel fuel for short or extended periods of time should have his or her fuel sampled regularly. There are some signs that your fuel has been contaminated, such as:
• Water in the bottom of your primary fuel filter/water separator is a sign of water infiltration.
• Black grit in your fuel filters, which is a sign that tars have formed during storage.
• A pinkish or milky coloring in the fuel is a sign of water contamination.
• Black colored fuel is a sign that bacteria or tars have been formed in the fuel.
• Black sediment in your fuel bowl is a sing of bacteria or tar build up.

Treatments, such as biocides, will kill the bacteria and fungus, however it will leave behind the sludge that will clog your filters. Tank Wizards will polish and rebuild your fuel, without leaving behind the sludge.
