What Is Marine Fuel Filtration?

Whether an engine is used for a marine vessel, aircraft, automobile, or other vehicle type, fuel filtration is extremely important for the protection and well-being of the fuel system and engine. Improperly filtered fuel can lead to contamination in the form of fluids or substances, all of which pose a risk to the operation of an engine. As fuel injectors and fuel injection pumps feature constricted orifices, contaminated fuel can quickly lead to damage and obstructions which can result in inefficiency of the engine turbine, inoperability, or a costly engine breakdown. As a result, it is crucial that marine vessel operators and owners fully understand the importance of marine fuel filtration and how it is upheld.

Contamination and water can reach the fuel tank of a marine vessel in a variety of ways, commonly due to incorrect placement of fuel tank breathers and tank fillers, internal fuel tank condensation, or contaminated fuel. While some forms of contamination can be avoided, factors such as condensation are much more complex. As such, marine fuel filtration acts to ensure that an engine and fuel system is always well protected. Marine fuel filtration is typically carried out through the use of fuel filters and water separators, those of which prevent damage resulting from dirt, salt water, and other various materials or substances.

 Despite serving an extremely important role, the marine fuel filtration system is actually quite simple. Generally, a water separating fuel filter consists of two elements, the top being a paper element while the bottom is a holding tank or bowl. Due to the difference in weight when comparing petrol to water, water will generally collect within the filter bottom element while petrol continues through the system. Once collected, the water can then be emptied from the system with an integrated tap. The paper element, on the other hand, serves to stop the flow of any materials such as dirt, dust, etc.

Filters will lose their performance and reliability over time, thus requiring regular inspections and maintenance to ensure proper filtration is taking place. The most common interval of changing fuel filters is whenever maintenance or oil changes are conducted. As such, filters may be replaced every 200 to 300 hours or on a calendar basis. Depending on the filter, fuel, and other factors, such components may also be replaced more often than required. In general, there are a few signs that one may look out for to determine when it is time for a replacement. Generally, brown fuel or filters are common signs, meaning that contaminates are escaping the filter and pushing through the system. The other common sign is a high vacuum gauge reading, yellow and red zones being an indicator that the filter needs replacement.

When managing the health of one’s fuel system and engine, one should utilize reliable sources for all parts, filters, and petrol. With a trustworthy source, customers can avoid the hassle of purchasing fuel that is contaminated, or fuel filters that offer poor performance characteristics.
