Fuel Pro® 485, 487 and 488

Applications and Features

The Fuel Pro 485, 487 and 488 models combine the features of fuel filtration, fuel/water separation and fuel filter preheating into a single, unit.

The Fuel Pro 485, 487 and 488 models are customized specifically for the new Detroit Diesel DD13, DD15 and DD16, Cummins and Navistar engines.

  • Fuel Pro 485: DTNA 2018 Cascadia
  • Fuel Pro 487: DTNA Classic Cascadia
  • Base Model: Unheated
  • Water-in-Fuel (WIF) Sensor
  • Electric pre-heater options (Heaters can be combined if desired)
    • 12 VDC pre-heater
    • 120 VAC overnight heater

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. Overnight heaters can be used to keep the fuel inside the Fuel Pro warm when the temperatures drop.
