Cleaning fuel filter
NOTE:
If any water is in the fuel, the float will rise. If
so, remove the cup and drain the water.
1. Unscrew the filter cup, catching any
spilled fuel in a rag.
2. Remove the filter element, and wash it in
solvent. Allow it to dry. Inspect the filter el-
ement and O-ring to make sure they are
in good condition. Replace them if neces-
sary. If any water is found in the fuel, the
Yamaha portable fuel tank or other fuel
tanks should be checked and cleaned.
3. Reinstall the filter element in the cup.
Make sure the O-ring is in proper position
in the cup. Firmly screw the cup onto the
filter housing.
4. Attach the filter assembly to the bracket.
5. Run the engine and check the filter and
lines for leaks.
