| Safety rules for work on the fuel supply system |
| When removing or installing the sender for the fuel level gauge or the fuel pump (fuel supply unit) when the fuel tank is full or part full, proceed as follows: |
Caution | The fuel supply lines are under pressure. Before loosening the hose connections, fit a cloth round the connection. Then eliminate the pressure carefully removing the hose. |
|
| t
| Before beginning work, the vacuum tube of a working extractor must be close at hand, near the fuel tank assembly opening, to absorb the fumes given off by the fuel. If an extractor is not available, a radial fan can be used (the engine must be kept out of the flow of air) with an air flow above 15 m3/h. |
| t
| Avoid contact between skin and fuel. Use fuel-resistant gloves! |
| If test and measuring apparatuses are required during a road test, take the following into account: |
| t
| Always place the test and measurement apparatuses in the rear seat and have a second mechanic operate them from there. |
| t
| If the test and measurement apparatuses are operated from the front passenger seat, the operator could be injured if the airbag is activated in the event of an accident. |
