INSPECTION AND MAINTENANCE
• As for the paper type, replace the filter and
gasket with new ones.
• For the steel mesh type, clean the
removed filter with clean diesel fuel, and
blow off the dirt and other impurities using
high-pressured air. Then, install the filter
and a new gasket.
3. Install the cover. Securely tighten it all the
way to the end using the wrench.
ADVICE
After the cover has been installed, make sure to check the airtightness.
The interval of replacement or cleaning should be shortened depending on the
status of fuel management and refuel.
