| Safety precautions when working on the fuel supply system |
| When removing and installing the fuel gauge sender or fuel pump (fuel delivery unit) from a full or partly full fuel tank the following must be observed: |
Caution | Fuel supply pipes are under pressure! Before removing from hose connection wrap a cloth around the connection. Then release pressure by carefully pulling hose off connection. |
|
| 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 fuel fumes. If no exhaust extraction system is available, a radial fan (as long as motor is not in air flow) with a displacement greater than 15 m³/h can be used. |
| t
| Prevent skin contact with fuel! Wear fuel-resistant gloves! |
| t
| For safety reasons fuse No. 40 must be removed from fuse holder before opening the fuel system, otherwise the fuel pump can be activated by the door contact switch in driver's door. |
