Safety precautions when working on the
fuel supply system
WARNING!
The fuel feed line is pressurized! Place a clean
cleaning cloth around the connection point before
detaching hose connections. Reduce pressure by
carefully releasing the connection point.
Pay attention to the following points when removing and
installing the fuel gauge sender or the fuel pump (fuel de-
livery unit) on a fuel tank that is filled or partially filled:
♦
The extraction hose of an exhaust extraction system
which is switched on, must be positioned close to the
assembly opening of the fuel tank in order to extract
the released fuel gases, even before the work is com-
menced. 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
♦
Avoid skin contact with fuel! Wear fuel-resistant
gloves!

Rules of cleanliness

Carefully observe the following „5 rules for cleanliness"
when working on the fuel supply and injection system:
♦
Thoroughly clean the connection points and their sur-
roundings before releasing.
♦ Place removed parts on a clean surface and cover. Do
not use fuzzy cloths!
