| Safety measures for working on the fuel 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
| In order to avoid damage to the lines, ensure sufficient clearance for all moving or hot components. |
|
| For removal and fitting the fuel level sender or the fuel pump (fuel supply unit) when the fuel tank is full or partially full, 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 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! |
