MAINTENANCE

Replacing the Fuel Filter

Replace the line-mounted fuel filter every 100 hours (once per season) or more regularly if it is clogged.

Replace the filter as follows:

1.Move the hose clamps away from the filter. Use flat-nosed pliers.

2.Pull the filter loose from the hose ends.

3.Push the new filter into the hose ends. Position the filter with the ”FLOW” arrow pointing up toward the fuel pump. If necessary, a soap solution can be applied to the filter ends to ease mounting.

4.Move the hose clamps back toward the filter.
