Safety precautions

1.1 Safety precautions when working on
fuel supply system
WARNING
When doing any repair work, especially in the engine compart‐
ment, pay attention to the following due to the cramped condi‐
tions:
♦ Route all the various lines (e.g. for fuel, hydraulics, acti‐
vated charcoal filter system, coolant, refrigerant, brake
fluid and vacuum) and electrical wiring in their original po‐
sitions.
♦ Ensure that there is sufficient clearance to all moving or
hot components.
♦ The fuel and the fuel lines in the fuel system can become
very hot (danger of scalding)!
♦ The fuel system is also under pressure! Before opening
the system, place cloths around the connections. Then
carefully loosen connection to release the pressure!
♦ Wear eye and hand protection when performing any type
of repair work on the fuel system!
When removing and installing fuel gauge sender or fuel pump
(fuel delivery unit) from a full or partly full fuel tank, observe the
following:
♦ Before beginning work, place an extraction hose close to
sender opening in fuel tank to extract escaping fuel fumes and
switch on exhaust extraction system. If no exhaust extraction
system is available, a radial fan with a displacement greater
3
than 15 m /h can be used providing that motor is not in air flow.
♦ Prevent skin contact with fuel! Wear fuel-resistant gloves!
