S08 MAINTENANCE
FUEL SYSTEM
Cleanliness requirements
IMPORTANT !
The whole fuel system is very sensitive to dirt and also
very small particles. Foreign particles in the system can
cause serious malfunctions. It is therefore very impo
tant that everything is as clean as possible when work is
carried out on the fuel system. Wash the engine before
carrying out repair work. If possible, a hot wash should
be used.
It is strictly forbidden to carry out any machining work
or work with compressed air near an open fuel system.
Be extra careful and always use clean, lint-free and
dust-free clothes and gloves when working on the fuel
system. Scania recommends using Tegera 848 gloves.
Clean tools before they are used and do not use any
worn or chrome-plated tools. Material and flakes of
chrome may come off.
Clean connections and the surrounding area before re-
moval. When cleaning, cloths or paper which shed fibres
must not be used. Use clean and lint free cloths, part
number 588 879.
Plug or cover the connections during removal. Also
clean the connections before the components are fitted.
Place removed components on a thoroughly cleaned,
dust-free surface. Scania recommends using a stain-
less steel bench top, part number 2 403 296. Cover the
components with a lint-free cloth.
Checking the fuel level
Check the fuel level and fill with fuel as necessary.
Note:
If the fuel tank has been run dry or if the engine has not
been used for a long time, bleed the fuel system. See the
section Venting the fuel system.

ENVIRONMENT
Use a suitable container. The fuel collected must be dis-
posed of as specified in national and international laws
and regulations.
1. Close the shut-off cock in the fuel pipe and position a
container under the filter.
2. Detach the sensor cables from the contact housings
(1) on the filters.
3. Open the filter drain plugs (2) and allow the fluid to run
down into the container.
4. Unscrew the filters (3) from the filter head (4).
5. Discard the old filters and use new ones.
6. Lubricate the O-rings on the filters with engine oil.
7. Fill the width of the filters with clean fuel.
8. Screw the filters into position until the Orings
rest against the filter head. Tighten the filters another
quarter to three quarter turn by hand.
9. Open the shut-off cock on the fuel pipe and check that
the fuel system is sealed.
10. Connect the sensor cable to the contact housings
on the filters.
11. Bleed the fuel system according to the instructions
in the Venting the fuel system section.
