| Safety precautions when working on fuel supply system |
WARNING | When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions: |
| t
| Route all the various lines and electrical wiring so that they are in their original positions. |
| t
| Ensure that there is sufficient clearance to all moving or hot components. |
| t
| The fuel and the fuel lines in the fuel system can become very hot (danger of scalding)! |
| t
| Fuel system is under pressure! The fuel supply system is also under pressure. Before opening the system, place cloths around the connections. Then carefully loosen connection to release the pressure! |
| t
| Wear eye and hand protection when performing any type of repair work on the fuel system! |
|
| 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
| Prepare exhaust gas hose of an activated exhaust gas extraction system before starting work. |
| t
| It should be used to extract released fuel gases in vicinity of fuel tank assembly opening. |
| t
| 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! |
