Safety Precautions When Working on Fuel Supply System

Safety Precautions When Working On Fuel Supply System

WARNING:
Observe the following for all installations, especially in engine compartment due to lack of room:
- Route lines of all types (e.g. for fuel, hydraulic, EVAP canister system, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.
- Watch for sufficient clearance to all moving or hot components.
- Fuel system is under pressure. Before opening system, place rags around the connection point. Then release pressure by carefully loosening connection.

Always observe the following when removing and installing the sender for fuel gauge or the Fuel Pump (FP) unit (fuel delivery unit) from full or partially filled fuel tanks:
- Before starting work, switch on exhaust extraction system and place an extraction hose close to the installation opening of fuel tank to extract escaping fuel fumes. If no exhaust extraction system is available, a radial fan (as long as motor is not in airflow) with a displacement greater than 15 cubic m/h can be used.
- Prevent fuel from contacting skin. Wear fuel-resistant gloves.
