FUEL FILTER / WATER SEPARATOR
The fuel filter/water separator assembly is located on left side of engine above starter motor (Fig. 13). The assembly also includes the fuel heater
and Water-In-Fuel (WIF) sensor.
The fuel filter/water separator protects the fuel injection pump by removing water and contaminants from the fuel. The construction of the
filter/separator allows fuel to pass through it, but helps prevent moisture (water) from doing so. Moisture collects at the bottom of the canister.
Refer to the maintenance schedules for the recommended fuel filter replacement intervals.
For draining of water from canister, refer to Fuel Filter/Water Separator Removal/Installation section.
A Water-In-Fuel (WIF) sensor is attached to side of canister. Refer to Water-In-Fuel Sensor Description/ Operation.
The fuel heater is installed into the top of the filter/separator housing. Refer to Fuel Heater Description/Operation.
