The fuel processor design uses only the amount of StrataPore filter media needed minimizing fuel restriction throughout the life of the filter. Use the clear cover to the fuel level. When the fuel reaches to top of the filter, it is time to change the filter. Reduce waste by using the full capacity of filter. Extended filter change intervals are based on useful filter life instead of mileage or calendar date.

For use with “SEEING IS BELIEVING®” Technology in DAVCO Fuel Processors.
