Caution
♦ Do not remove fuel hoses from the fuel filter.
♦ Pay attention to the notes
⇒ "2.6 Fuel hoses in the engine compartment",
page 222 .
♦ Do not lever the connection fittings.
♦ This leads to leaks and damage to the fuel filter top part.
♦ Ensure that no diesel fuel gets onto other components in
the engine compartment. If this happens, clean affected
components immediately!
Caution
♦ Because of insufficient lubrication by diesel fuel, misfuel‐
ling can cause irreversible damage to high pressure com‐
ponents, particularly the high pressure pump. Damage in
the form of engine seizure and clogging by particles can
be expected. These particles create a risk of further dam‐
age in the pressure control valve and injectors.
Caution
In order to avoid the high pressure pump to run dry and to ach‐
ieve a quick engine start after parts are replaced, the following
points must be observed.
♦ If parts of the fuel system have been removed or replaced,
to bleed the fuel system it is necessary to perform the fuel
system filling/bleeding process
⇒ "1.3 Filling/bleeding the fuel system", page 321
♦ If the fuel pump, fuel line or fuel filter have been removed
or replaced, the fuel system filling/bleeding process must
be performed
⇒ "1.3 Filling/bleeding the fuel system", page 321
♦ If the high pressure pump is removed or replaced, the in‐
itial fuel filling of the high pressure pump must be carried
out before the first engine start
⇒ "1.3 Filling/bleeding the fuel system", page 321
♦ If the high pressure system was opened, it must be
checked for tightness
⇒ "1.4 Check the fuel system for tightness", page 322
When removing and installing the fuel gauge transmitter or the
fuel delivery unit from a full or partly filled fuel tank, pay attention
to the following points:
♦ The extraction hose of an exhaust extraction system which is
switched on, must be positioned close to the assembly open‐
ing of the fuel tank in order to extract the released fuel vapours,
even before the work is commenced. If no exhaust extraction
system is available, a radial fan (motor not in air flow of fan)
with a delivery volume of more than 15 m
♦ Prevent skin contact with fuel! Wear fuel-resistant gloves!
