Diesel Pro® 245

Applications and Features

Diesel Pro 245
The Diesel Pro 245 combines the features of fuel filtration, fuel/water separation and fuel filter preheating into a single, compact unit. The DIesel Pro 245 uses three stage filter technology for superior fuel/water separation.

Designed for medium duty and school bus applications

Models and Options
  • Base Model - Unheated
  • Electric Pre-heater Options: 12 VDC 24 VDC or 120 VAC Overnight heater Water-In-Fuel (WIF) sensor (NOTE: You can’t have both 12 VDC 24VDC and 120 VAC in this housing, only one heating option.)
  • Water-In-Fuel (WIF) sensor
  • Primer Pump

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.

Draining Procedure

Draining the Diesel Pro 245

Note: In 2018, the drain design was changed to use a wrench to loosen the drain. Tighten by turning it until contact, and then tighten with another 1/4 turn.
