The sedimenter separates water from fuel. It is integral
with the fuel filter.
When the sedimenter warning light comes on, it
indicates that more than the specified amount of water
has accumulated in the sedimenter. Remove the water
in the following manner:
1. Shut down the engine.
2. Turn the drain cock (plug) 4 or 5 turns to loosen it.
NOTE
Do not loosen the drain cock excessively; otherwise
fuel might spill.
3. Pump the priming pump a few times to drain water
from inside the sedimenter.
4. Tighten the drain cock (plug) securely and pump the
priming pump another few times to make sure there
is no fuel leak from the drain cock (plug) .
CAUTION
Wipe away any spilt fuel from areas around the
sedimenter. There is a danger of causing a fire
hazard.
5. Start the engine and make sure the sedimenter
warning light is off.
