light up. When removing connector (5), be extremely

• If water sticks to connector (5), dry it completely be-
fore connecting it.
14. Turn valve (1) at the bottom of the fuel tank to OPEN posi-
tion (O).
15. Install drain hose.
16. Fill up the fuel tank with fuel (to the level where the float is
at the highest position).
17. Loosen the knob of feed pump (7), pull it out, then pump it
in and out until the movement becomes heavy.
It is not necessary to remove the plugs at the fuel prefilter
head and at the fuel main filter head.
When the engine runs out of fuel, use the same procedure
to operate feed pump (7) and bleed the air.
18. After bleeding air, push in the knob of feed pump (7).
19. After replacing the filter cartridge, start the engine and run
it at low idle for 10 minutes.
20. Check for leakage of oil from the filter seal surface and
transparent cup mounting face.
If the leakage is noticed, check the filter cartridge for its tightening condition.
If there is still fuel leakage, repeat steps 1 to 6 and remove the filter cartridge. If any damage or pinched foreign
material on the packing surface is found, replace it with a new cartridge, and repeat steps 7 to 12 to install it.
