For dramatic examples of why you need a fuel filter, or fuel-water separator, on your boat, look no further than the accompanying video!
John Bernier of North Atlantic Marine Services in Wareham, Massachusetts, sees plenty of horror stories in the making when he pulls the filters from his customers’ boats at the end of the season. In fact, he estimates that as much as 75 percent of the filters he changes contain water, sediment or other contaminants!
In the video, Bernier emphasizes the importance of fuel filters, and discusses some of the finer points of filter selection. He also shows some examples of water captured by the filter (“a filter doing its job”), and talks about how often you should change the filter and examine the fuel inside.
