Fuel Tank Water and Sediment - Drain
Illustration 96
(1) Fuel supply connections
(2) Fuel filters
(3) O-ring seal
NOTICE
Do not allow dirt to enter the fuel system. Thoroughly
clean the area around a fuel system component that
will be disconnected. Fit a suitable cover over any
disconnected fuel system components.
NOTICE
Use a suitable container to catch any fuel that might
spill. Clean up any spilled fuel immediately.
1. It may be necessary to relieve residual fuel
pressure from the fuel system before removing the
fuel filter.
Loosen one of the fuel supply connections (1) to
purge any residual pressure.
NOTICE
Do not loosen fuel lines or fittings at the fuel manifold
or ECM. The engine components may be damaged.
2. Remove the used fuel filter.
3. Clean the O-ring sealing surface of the fuel filter
base.
4. Apply clean diesel fuel to the new fuel filter O-ring
seal.
Do not fill the secondary and tertiary fuel filters with
fuel before installing. The fuel would not be filtered
and could be contaminated. Contaminated fuel will
cause accelerated wear to fuel system parts.
5. Install the new fuel filter. Spin the fuel filter onto the
fuel filter base until the O-ring seal contacts the
base. Use the rotation index marks on the filters as
a guide for tightening correctly. Tighten the filter for
an extra 3/4 turn by hand. Do not overtighten the
filter.
Fuel Tank Water and Sediment
- Drain

Care must be taken to ensure that fluids are con-
tained during performance of inspection, mainte-
nance, testing, adjusting and repair of the product.
Be prepared to collect the fluid with suitable contain-
ers before opening any compartment or disassem-
bling any component containing fluids.
Dispose of all fluids 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 filled.
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.
Check the fuel daily. Allow five minutes after the fuel
tank has been filled before draining water and
sediment from the fuel tank.
