Open the rear hood. The secondary fuel filter is located on the right side of the machine.Note: This machine is equipped with two secondary spin-on filters on a single filter base. The upper filter is upside-down. Always drain the inverted filter before you remove the lower filter or before you remove the upper filter.

Drain the upper filter (2) (inverted filter). Place a suitable container under the drain valves. Open the drain valve (3) first. Then, immediately open drain valve (4). Drain the fuel into a suitable container. When the fuel stops draining, keep the drain valves open. Loosen the inverted filter for 1/4 turn. As the filter is loosened, additional fuel may drain from the drain valves. When the fuel stops draining, loosen the filter for an additional 1/4 turn. Observe the flow of the fuel. Repeat this procedure until fuel does not drain from the drain valves. Close the drain valves. Properly dispose of the fuel.Note: Make sure that the drain valves are opened in the proper order. If you open the wrong drain valve first, an air lock in the fuel system may occur. This will not allow fuel to drain from the upper filter.
Hand tighten the upper filter until the seal contacts the base. Then, tighten the upper filter for an additional 3/4 turn.Rotation index marks are positioned on the filter at 90 degree intervals. Use these rotation index marks as a guide when you tighten the filter.
Remove the lower filter (1) .Note: Lower filter (1) has not been drained. The filter contains fuel. When you remove the lower filter, use caution in order to avoid spilling the fuel.
Inspect the fuel filter element for debris by cutting the filter open. Discard the used fuel filter element properly.
Clean the mounting base of the fuel filter. Make sure that all of the old seal is removed from the mounting base of the fuel filter.
