Safety precautions when working on the fuel supply system
Safety precautions when working on the fuel supply system
  WARNING
When undertaking all assembly work, particularly in the engine compartment due to its cramped construction, please observe the following:
t  Lay lines of all kinds (e.g. for fuel, hydraulic fluid, the active charcoal container-unit, cooling fluid and refrigerant, brake fluid, vacuum) and electrical lines in such a way that the original line guide is re-established.
t  Ensure that there is adequate free access to all moving or hot components.
The fuel delivery unit is activated when the ignition is switched on and by the door contact switch of the driver door. For safety reasons, before opening the fuel system and in the event that the battery is not disconnected:
   
t  Remove fuse No. 61 from the fuse holder.
  S01-0094
t  or disconnect the plug -arrow- from the fuel delivery unit.
Pay attention to the following points when removing and installing the sender for fuel gauge display -G- or the fuel pump (fuel delivery unit) from the fuel tank:
  WARNING
The fuel system is under pressure! Place a clean cleaning cloth around the connection point before detaching hose connections. Reduce pressure by carefully removing the hose.
t  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 vapours, even before the work is commenced. 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 m3/h must be used.
t  Avoid skin contact with fuel! Wear fuel-resistant gloves!
