| Safety precautions when working on fuel supply system |
WARNING | When doing any repair work, especially in the engine compartment,
pay attention to the following due to the cramped conditions: |
| t
| Route all the various lines and electrical wiring so that they
are in their original positions. |
| t
| e.g. for fuel, hydraulics, activated charcoal filter system,
coolant and refrigerant, brake fluid, vacuum. |
| t
| Ensure that there is sufficient clearance to all moving or
hot components. |
| t
| The fuel and the fuel lines in the fuel system can become very
hot (danger of scalding)! |
| t
| The fuel system is also under pressure! Before opening the
system, place cloths around the connections. Then carefully loosen
connection to release the pressure! |
| t
| 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: |
| t
| Before starting work, the extraction hose of a switched-on
exhaust gas extraction system must be laid near to the assembly opening
of the fuel tank. This draws away the fuel fumes that escape. If no
exhaust gas extraction system is available, a radial fan with a displacement
greater than 15 m3/h can be used providing that motor
is not in air flow. |
| t
| Prevent skin contact with fuel! Wear fuel-resistant gloves! |
