Fuel Mesh Filter Inspection and Cleaning
B718H11706036
Inspect the fuel mesh filter in the following procedures:
1) Remove the fuel mesh filter. Refer to “Fuel Pump
Disassembly and Assembly (Page 1G-12)”.
2) If the fuel mesh filter is clogged with foreign particles,
it hinders smooth gasoline flow resulting in loss of
engine power. Such a filter should be cleaned by
blowing with compressed air.
NOTE
When the fuel mesh filter is dirtied
excessively, replace the fuel filter cartridge
with a new one.
3) After finishing the fuel mesh filter inspection, reinstall
the fuel mesh filter. Refer to “Fuel Pump
Disassembly and Assembly (Page 1G-12)”.
