fuel tank filter.
2. Wipe foreign substances off the filter with a
clean cloth or blowing them off using an air
compressor.
3. Reinstall the filter and cover on the fuel tank.

5. If the pressure sensor warning persists, replace
the fuel filter cartridge. This replacement is one
of the items described in the subsection of
“Every 500 Service Hours or 3 Months.
