Choosing The Right System

Our systems are rated in total fuel FLOW, that is the fuel burned and the fuel returned to the tank. If your engine burns 2 gallons per hour (GPH) and returns 15 GPH it would be a total of 17 GPH.
For this example, we would recommend the FC60 system with a rated filter fuel flow from 0-60 GPH. If your fuel flow is more than 70% of the rated system, go to the next higher size. This will allow for more fuel filtration.


FC60 FC90 FC180 FC600


0-60 GPH 0-90 GPH 0-180 GPH 0-600 GPH
You may also want to consider your fuel tank size and flow needed during the “Polishing” mode.
