| 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 avoid damage to lines, ensure sufficient clearance to all moving or hot components. |
|
| When removing and installing fuel gauge sender -G- or fuel pump (fuel delivery unit) from a full or partly full fuel tank, observe the following: |
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
| Even before work commences, the extraction hose of an activated fume extraction system has to be placed in the vicinity of the assembly opening of the fuel tank to extract any escaping 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 fuel coming into contact with the skin! Use fuel resistant gloves! |
