Safety Precautions When Working on the Fuel Supply System

Safety precautions when working on the fuel supply system

WARNING! When performing repair work, especially due to the confined conditions in the engine well, pay attention to the following:
^ Route all types of lines (e.g. for fuel, hydraulics, EVAP system, coolant, refrigerant, brake fluid and vacuum) as well as electrical wiring so that the original positions are restored.
^ Ensure sufficient clearance to all moving or hot components.

^ 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:

WARNING! Fuel supply lines are under pressure! Before removing from hose connection wrap a cloth around the connection. Then release pressure by carefully pulling hose off connection.

^ 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 with a displacement greater than 15 m3/h can be used (as long as the motor is not in the air flow).
^ Prevent skin contact with fuel! Wear fuel-resistant gloves!





^ For safety reasons, fuse No. 28 must be removed from the fuse holder before opening the fuel system. The fuel pump can be activated by the door contact switch in driver's door.
