Safety Precautions When Working On Fuel System
CAUTION:
There Is a Risk of Injury Because the Fuel Is Under Pressure
The fuel system is under pressure. Injuries are possible from fuel spraying out.
Before opening the fuel system:
-- Wear protective eyewear.
-- Wear safety gloves.
-- Reduce the pressure: Place clean cloths around the connection point and carefully open the connection point.
CAUTION:
Risk of a Fire Due to Leaking Fuel
When the battery is connected, the door contact switch activates the fuel pump when opening the driver door. Leaking fuel can ignite and start a fire.
-- Before opening the fuel system, cut off the fuel pump power supply.
Perform the Following Steps Before Starting Work on the Fuel System:
- The fuel tank must be either completely empty or only partially filled. How much fuel can remain in the fuel tank may be read in the respective procedure description. Drain the fuel tank, if necessary. Refer to FUEL TANK, DRAINING .
- Before starting the procedures, switch on the exhaust extracting system and place an extraction hose near the installation fuel tank opening 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 delivery volume greater than 15 m3 /h can be used.
