Fuel Filtration and Testing for Critical Site Generators


Why is Fuel Filtration Important?

The main benefit of performing fuel filtering is fuel can be high in bacteria, there can be water in the fuel tank, or the fuel can have high particulate levels. All of this can harm your generator. If the fuel doesn’t stay clean, the filters inline at the generator can clog, and the generator shuts down.


How do we Perform Fuel Filtration? 

To filter the fuel, we first set up a diaphragm pump driven by an air compressor and then connect hoses to the fuel tank, diaphragm pump, and filter station in our trailer. Then we join a return hose back to the fuel tank. 

We typically do a minimum of 3 turns to ensure the entire tank gets filtered. So if a tank is 10,000 gallons at 90% ullage, we are pumping 27,000 gallons through the pump and filter station. We take samples of the fuel before and after the process to see if we can see any difference in the quality.


After polishing, we take a final sample that goes in for testing. This sample will tell if there is water, bacteria, or particulates in the tank. If the tank is still coming up dirty, we then talk to the customer and see if we can turn it even more to get a better result. If the fuel cannot be cleaned, it must be disposed of and replaced with new clean fuel. It may even require a tank cleaning before the new fuel is added.
