FUEL FILTER / WATER SEPARATOR
DESCRIPTION
The fuel filter/water separator assembly is located in the left rear corner of the engine compartment. It incorporates
the fuel system prime button, bleed screw, fuel temperature sensor, fuel heater and a water in fuel (WIF) sensor.
Only the fuel filter canister and the WIF sensor are serviced separately. The fuel filter has a 3 micron element and
tightens clockwise to the housing..
OPERATION
The fuel filter/water separator protects the high pressure fuel injection pump by removing water and contaminants
from the fuel with a three micron filter element. 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 14 - FUEL SYSTEM - STANDARD PROCEDURE).
A Water-In-Fuel (WIF) sensor is attached to the fuel filter and serviced separately. Refer to Water-In-Fuel Sensor
Description/Operation.
The fuel heater and fuel temperature sensor are part of the fuel filter assembly head and not serviced separately
from the head.
