Safety precautions when working on the fuel supply system
WARNING: This page does not describe the selected car, but rather 20 other vehicles, including the 2009 Volkswagen Golf, 2008 Volkswagen Golf, 2007 Volkswagen Golf, 2006 Volkswagen Golf, and 2005 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When performing repair work, especially due to the confined conditions in the engine compartment, 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 the fuel pump (fuel delivery unit) the following must be observed:
WARNING:
- The fuel system is under pressure! Before opening the system place a cloth around the connection. Then release the pressure by carefully loosening the connection.
- Always wear eye protection and wear fuel-resistant gloves when disconnecting system connections.
- Before beginning 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 motor is not in air flow).
- Prevent skin contact with fuel! Wear fuel-resistant gloves!
All engines
- For safety reasons, fuse No. 28 must be removed from the fuse holder before opening the fuel system. This is because the fuel pump can be activated by the door contact switch in driver's door.
