Prevent engine performance loss by monitoring fuel filter.

As fuel filters fill with rust, debris, and algae the fuel flow through them decreases. This can lead to de-gassing of fuel and can reduced engine performance and efficiency. Boaters can stay on top of fuel filter condition by using fuel filter indicator gauge to monitor fuel flow restriction caused by the filter. This Racor gauge provides a visual indicator to alert boaters to changes in filter performance. A yellow indicator moves to show gradually increased fuel restriction until it reaches a red service area noting it is time for a filter change. After the service is complete a top mounted reset button clears the gauge.
