How do you really know what is in your fuel tank? With the Filtratech Fuel Sampling Kit, you can visually analyze your fuel for contaminants such as sludge and water. Fuel deterioration occurs naturally over time and is greatly influenced by weather and other environmental factors. Water builds up in the tank through condensation and transportation. The presence of water leads to bacterial colonization and fungal growth, along with clouding and gel formation. Only through sampling your fuel can you know when these conditions exist and take corrective action to keep your diesel equipment running smoothly, cleanly, and in compliance with manufacturer’s warranty requirements.
