Clean the filter head, fill the new filter cartridge with clean fuel,
coat the packing surface thinly with engine oil, and install it to
the filter holder.
Always use clean fuel when filling with fuel, and be careful not
to let any dirt or dust get in.
Add fuel from small hole (A) (dirty side) at eight places. Do not
add fuel from hole (B) (clean side) at the center.

When installing the seal, tighten it so its surface comes into
contact with the filter holder, then tighten another 3/4 turn.
If the filter cartridge is tightened too far, the packing will be
damaged and this will lead to leakage of fuel. If the filter
cartridge is too loose, fuel will also leak from the packing, so
always tighten to the correct amount.

come out of air bleeding plug (2), followed by fuel.

8. After replacing the filter cartridge, start the engine and check that there is no leakage of fuel from the filter seal
surface. If there is any leakage of fuel, check the tightening of the filter cartridge. If there is still leakage of fuel,
follow Step 1 and 2 to remove the filter cartridge, then check the packing surface for damage or foreign material.
