FUEL MESH FILTER INSPECTION AND 
CLEANING

• If the fuel mesh filter is clogged with sediment or rust, fuel will

not flow smoothly and loss in engine power may result.

• Blow the fuel mesh filter with compressed air.

NOTE:
If the fuel mesh filter is clogged with many sediment or rust,
replace the fuel filter cartridge with a new one.

• When installing the fuel pump assembly, first tighten all the

fuel pump assembly mounting bolts lightly in the ascending
order to numbers, and then tighten them to the specified
torque in the above tightening order.

Use the new O-ring to prevent fuel leakage.

Install the fuel filter so that “OUT” mark
