2. Place a container under the fuel filter (1) to collect
spilled fuel.
3. Remove the fuel filter.
NOTE:
Always use SANY-approved fuel filters.
4. Clean the mounting base of the fuel filter and fill the
new fuel filter with clean fuel. Apply a thin film of oil
onto the O-ring and install the new fuel filter onto the
filter housing.

turn the fuel filter an additional 1/2 turn. Overtightening
the filter may damage the O-ring, resulting in a fuel leak.
