Drain Water From Fuel Filters

A - Primary Fuel Filter

B - Final Fuel Filter

C - Drain Valves

The primary fuel filter is equipped with a sensor that detects the presence of water in the fuel filter element. This sensor will illuminate the red “STOP ENGINE” warning light on the diagnostic gauge and also sound an audible alarm. A Diagnostic Trouble Code (DTC), a description of the trouble code and the corrective action needed will be displayed on the diagnostic gauge.

ALWAYS STOP ENGINE IMMEDIATELY and drain water from the primary (A) and final fuel filter (B) when these warnings occur.

1. Loosen drain valves (C) to drain water and debris as needed.

2. Retighten valves securely.

NOTE: Also replace fuel filter elements when amber indicator on instrument panel lights up AND Diagnostic Trouble Code (DTC) in diagnostic gauge window indicates plugged fuel filters (“low fuel pressure”). To replace fuel filter elements, see Replacing Fuel Filters in Lubrication and Maintenance, 500 Hour/12 Month.
