Maintenance: Fuel system
Fuel system
Use only fuel recommended in the fuel specifications below. Always observe cleanliness when refuelling and
working with the fuel system.
All work concerning the engine injection pump or injectors is to be carried out at an authorised workshop. Break-
ing the seal on the injection pump will void the warranty.
WARNING! Fire hazard. Work performed on the fuel system must be done on a cold engine. Fuel spill on
hot surfaces or electrical components can cause fires. Keep fuel-drenched rags where they are safe in case
of fire.
Fuel specification
Fuel must comply with national and international stan-
dards at the least, e.g.:
EN590 (with national environment and cold require-
ments)
ASTM-D975-No 1-D, 2-D
JIS KK 2204
Sulphur content
Complying with legal requirements in each country. If
the sulphur content exceeds 0.5 wt%, service inter-
vals must be changed, see “Maintenance: Lubricating
system”.
Fuels with low density (city diesel) can result in a loss
of power by approx. 5% and an increase in fuel con-
sumption of approx. 2–3 %.
Fuel delivery pipes
The delivery pipes must not be bent, twisted or ex-
erted to any other forces. Change delivery pipes that
are damaged.
WARNING! Fire hazard! The fuel delivery pipes
must not be bent, twisted or exerted to any other
