Changing the Fuel Filter
1. Loosen the drain plug at the bottom
of the filter element case. Remove the
rubber cap of the air bleed plug and
then loosen the plug. This will allow
the fuel in the filter element case to
drain through the drain plug. Tighten
the air bleed plug.
2. Disconnect the water separator switch
connector.
3. Use a tool (like a 29 mm (1.14 in)
socket wrench) to turn the hexagonal
part at the bottom of the element case
counterclockwise and remove the
element case.
• Check the float at the bottom of the
interior of the filter element case for
free and smooth movement.
• Connect the water separator switch
connector, turn the filter element
case upside down, and confirm
that the water separator (fuel filter)
warning light comes on.
• Clean any foreign matter or dirt at
the bottom inside the filter element
case.
