| 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/wiring, 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 eliminate the pressure by carefully separating the pipe. |
|
| t
| Already 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 fuel 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! |
