Fuel Tank Water and Sediment - Drain
Illustration 93
Typical example
Note: The fuel system has two secondary filters, both
must be replaced.
3. The residual fuel pressure in the fuel system may
need relieving. Wait from 1 minute to 5 minutes
until the fuel pressure has lowered.
4. Use a suitable tool remove the spin on fuel filter
(3).
5. Ensure the sealing surface (1) is clean. Lubricate
the O ring seal (2) on the new spin on filter with
clean diesel fuel.
6. Install the new spin on filter (3) to the filter base.
Spin on the filter until the O ring seal (2) contact
the sealing surface (1). Then, rotate the spin on
filter 1 full turn.
7. Replace the other secondary fuel filter, refer to
step 2 through to step 6.
8. Turn on the fuel supply valve. Dispose of the fluid
and old filters in accordance with local regulations.
9. The primary fuel filter the secondary fuel filter must
be replaced at the same time. Refer to the
Operation and Maintenance Manual, "Fuel System
Primary Filter (Water Separator) Element -
Replace". The engine will need to be purged of air.
With primary and secondary fuel filters replace,
Refer to Operation and Maintenance Manual,
"Fuel System Prime".
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
g06042986
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.
Fill the fuel tank after operating the engine in order to
drive out moist air. This will help prevent
condensation. Do not fill the tank to the top. The fuel
expands as the fuel gets warm. The tank may
overflow.
