NOTICE
When filling the filter cartridge with fuel, carry out the filling operation with
cap (A) fitted.
Cap (A) acts to prevent the entry of dirt or dust into the filter cartridge.
7. Fill the filter cartridge with clean fuel through the 8 small holes
(B) in the new filter cartridge.
8. Coat the packing surface of the filter cartridge with oil.
9. Remove filter cartridge cap (A) and install to the filter holder.
10. When installing, tighten until the packing surface contacts the seal surface of the filter holder, then tighten it 3/4
of a turn.
If the filter cartridge is tightened too far, the packing will be damaged and this will lead to leakage of fuel. If the
filter cartridge is too loose, fuel will also leak from the packing, so always tighten the correct amount.
When tightening with a filter wrench, be extremely careful not to dent or damage the filter.
11. Check that the drain plug at the bottom of the water separator cup is tightened securely.
Tightening torque: 0.2 to 0.45 Nm (0.02 to 0.046 kgm, 0.1 to 0.3 lbft)

13. When replacing the fuel main filter cartridge (EVERY 1000 HOURS), replace the cartridge, then bleed the air.
For details, see "REPLACE FUEL MAIN FILTER CARTRIDGE (PAGE 4-67)". Do not put any fuel in the fuel
main filter cartridge.
14. Start the engine, check that there is no leakage of fuel from the filter seal surface or water separator mounting
surface, then run for approx. 10 minutes at low idling.
