Fuel Filter Inspection And Replacement - Honda Car engines GX640 Owner's Manual

FUEL FILTER INSPECTION AND REPLACEMENT
A fuel filter must be installed between the fuel tank and carburetor
to prevent any dirt or sediment from reaching the carburetor.
The fuel filter available from Honda (shown below) should be
inspected periodically and must be replaced if there is an accumu-
lation of dirt. Additionally, scheduled replacement every year, or
300 operating hours, will help to ensure continued troublefree
operation.
If another type of fuel filter is installed, follow the inspection and/or
replacement recommendations of the filter manufacturer.
