SEEING IS BELIEVING®
The combination of the clear cover on top and the three layer filter cartridge ensures better water separation, longer filter life and provides instant visual diagnostics of fuel quality to protect engine system components.
Extended Filter Life
Change the filter only when the fuel reaches the black band on the filter wrap. As the fuel rises inside the filter cover, the vapor pressure relief valve on the cap equalizes pressure and allows more of the filter media to be used.
The color of the fuel and the filter media is not an indication of when to change the filter as there is still unused media under the filter wrap.
Fuel Heating
Electric pre-heaters warm the fuel once the ignition key is turned.
