Replacing the Fuel Filters
Service Interval: Every 500 hours
The engine on this machine uses a dual fuel-filter system, with
a primary fuel filter and a secondary fuel filter. The primary
fuel filter includes a fuel-water separator; it is not pressurized
but operates under a vacuum. The secondary fuel filter is for
filtration only and is pressurized by the fuel pump.
Removing the Primary and Secondary Fuel Filters
Important: Clean all around the filter area before
disassembling the fuel filter system. Dirt or
contaminants can damage the fuel system.
1. Rotate the battery disconnect switch to the Off
position; refer to
2. Remove the right side panel; refer to
Side Panels (page
3. Clean the area around the primary and secondary fuel
filters.
4. Disconnect the wiring harness from the water-in-fuel
sensor.
Note: The water-in-fuel sensor is located at the
bottom of the fuel/water separator, next to the drain
valve.
5. Place a small-drain container under the drain valve of
the fuel water separator ; refer to
the Fuel-Water Separator (page
Note: The primary fuel filter is a component of the
fuel/water separator.
6. Open the drain valve and allow the fuel-water separator
to drain completely; refer to
Fuel-Water Separator (page
7. Loosen and remove the primary fuel filter
Note: If necessary, use a filter wrench to loosen the
fuel filter.
