At Kaydon Filtration, we recognize that keeping fuel clean and dry can be particularly challenging in marine environments. Substandard fuel, contaminated by excessive particulate and water, is one of the major reasons for diesel engine problems.  Particulate and water can appear in diesel fuel for one or more of the following reasons: 

1. Diesel fuel is not filtered as it is transported through the fuel distribution network.
2. During fuel transportation, diesel fuel picks up particulate and water.
3. Diesel fuel has an affinity to attract moisture in marine environments, especially those offshore. 
4. Fuel storage on a workboat, especially those venturing out into deeper water, have more time for condensation collection.
5. Workboats operating internationally. where diesel fuel quality is suspect, can introduce high levels of contamination. 

To address the many issues that affect fuel contamination, Kaydon Filtration offers a complete selection of diesel fuel purification products geared directly at keeping diesel fuel clean and dry for diesel-driven marine equipment.
