Safety precautions when working on the fuel supply system
  Caution
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 (e.g. for fuel, hydraulics, activated charcoal filter system, coolant, refrigerant, brake fluid and vacuum) and electrical wiring in their original positions.
t  To avoid damage to lines, ensure sufficient clearance to all moving or hot components.
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 commencing work, switch on exhaust extraction system and place an extraction hose close to the sender opening in the fuel tank to extract escaping petrol fumes. If no exhaust extraction system is available, a radial fan with a displacement of at least 15 m3/h can be used (the fan motor must be clear of the air stream).
t  Prevent skin contact with fuel! Wear fuel-resistant gloves.
