Common Concerns Answered
How often should I replace the filter element?
Filter element replacement frequency depends on fuel quality and usage, but a visual inspection of the clear bowl for accumulated water and sediment is recommended before each outing. A general guideline is to replace annually or when significant contamination is observed.
Will this filter work with diesel fuel?
This Dometic M18-01500 is specifically designed and rated for gasoline fuel systems on Nissan/Tohatsu outboards. Using it with diesel will not provide adequate filtration and could damage the filter or engine.
Does this filter also remove ethanol damage?
While this filter primarily removes water and particulate contaminants, the use of ethanol-resistant materials in its construction helps mitigate some of the damaging effects ethanol can have on fuel system components.
