Fuel Pro® 385 and 386

Applications and Features

The Fuel Pro 385 combines the features of fuel filtration, fuel/water separation and fuel filter preheating into a single unit. It is intended for any diesel engine with:
  • Flow rates up to 180 GPH
  • Three layer filter technology for the NEW Western Star 4900
  • Biodiesel/Renewable Fuel Compatibility
Models and Options
  • Base Model: Unheated
  • Electronic Water in Fuel Sensor (WIF)
  • Electric pre-heater (Heaters can be combined if desired)
    • 12 VDC pre-heater
    • 120 VAC overnight heater

The combination of the clear cover on top, the EleMax filter cartridge and the Statapore filter media 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.

Three Layer Filter Technology

Three layer filter technology provides superior fuel/water separation.
