Typical example
1.
Place a suitable container under the water
separator in order to catch any
fl
uid that might
spill. Clean up any spilled
fl
uid. Ensure that the
outer body of the
fi
lter assembly is clean and free
from dirt.
2.
Install a suitable tube onto drain (3). Loosen the
cap (1) in order to allow atmospheric pressure to
act upon the fuel. Rotate the cap 3 and a half turns
in order to allow the vent hole to be accessed.
Open the drain valve (2) and allow the
fl
uid to
drain.
3.
When fuel free of water comes from the drain
valve, close the drain valve and tighten the vent
cap to 30 N·m (22 lb ft)
4.
Remove the drain tube and depose of the drain
fl
uid in accordance with local regulations.

Fuel Tank Water and Sediment
- Drain
NOTICE
Care must be taken to ensure that
fl
uids are contained
during performance of inspection, maintenance, test-
ing, adjusting, and repair of the product. Be prepared
to collect the
fl
uid with suitable containers before
opening any compartment or disassembling any com-
ponent containing
fl
uids.
Dispose of all
fl
uids according to local regulations and
mandates.
Fuel Tank
Fuel quality is critical to the performance and to the
service life of the engine. Water in the fuel can cause
excessive wear to the fuel system.
Water can be introduced into the fuel tank when the
fuel tank is being
fi
lled.
Condensation occurs during the heating and cooling
of fuel. The condensation occurs as the fuel passes
through the fuel system and the fuel returns to the
fuel tank. This causes water to accumulate in fuel
tanks. Draining the fuel tank regularly and obtaining
fuel from reliable sources can help to eliminate water
in the fuel.
Drain the Water and the Sediment
Fuel tanks should contain some provision for draining
water and draining sediment from the bottom of the
fuel tanks.
Open the drain valve on the bottom of the fuel tank
in order to drain the water and the sediment. Close
the drain valve.
