Typical example
1.
Locate the thread (7) in the filter element onto the
threads (6). Spin on the new filter element and
tighten the drain valve (3) by hand.
2.
Lubricate the seal on the filter element (5) with
clean engine oil. Do NOT fill the filter bowl (2) with
fuel before the filter assembly is installed.
3.
Do not use a tool in order to install the filter
assembly. Tighten the assembly by hand. Install
the filter bowl (2). Turn the filter bowl clockwise
until the filter bowl locks into position against the
stops.
4.
Filter assembly (A) is now complete. Perform the
same procedure on filter assembly (B).
5.
When both filter elements have been replaced with
new filter elements the fuel system can be primed,
if the primary filter has also been renewed. If
necessary, turn the fuel supply valve to the ON
position.
6.
Prime the fuel system. Refer to the Operation and
Maintenance Manual, “Fuel System - Prime” for
more information.

Fuel Tank Water and Sediment

NOTICE
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 containers
before opening any compartment or disassembling
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.
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.
Some fuel tanks use supply pipes that allow water
and sediment to settle below the end of the fuel
supply pipe. Some fuel tanks use supply lines that
take fuel directly from the bottom of the tank. If the
engine is equipped with this system, regular
maintenance of the fuel system filter is important.
