| Safety precautions when working on 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
| All the various lines (e.g. fuel, hydraulic system, active carbon filter system, coolant, refrigerant, brake fluid and vacuum pipes and hoses) and electrical wiring must be installed in their original positions. |
| t
| To prevent damaging the hoses, ensure that all mobile or hot components are easily accessible. |
|
| When fitting or removing the sensor for the fuel gauge -G- or the fuel pump (fuel delivery unit) when the fuel tank is full or partially filled, the following must be observed in all cases: |
WARNING | Fuel system is under pressure! Wear eye protection and gloves to avoid injuries and skin contact. Before loosening hose connections, wrap a cloth around the connection. Then release pressure by carefully pulling hose off connection. |
|
| 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 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
| Avoid skin contact with the fuel! Use fuel resistant gloves! |
