Safety precautions when working on fuel supply system
WARNING: This page is about a different car, the 2004 Volkswagen R32. However, it is still accessible from the selected car via links, so may be relevant.
- For safety reasons, fuse No. 28 must be removed from fuse holder before opening fuel system as fuel pump can be activated by door contact switch in drivers door.
CAUTION:
Fuel system is under pressure! Wear eye protection and protective gloves to avoid injuries and skin contact with fuel. Before removing from hose connection wrap a cloth around the connection. Then release pressure by carefully pulling hose off connection.
Always observe the following when removing and installing the sender for fuel gauge or the fuel pump (fuel delivery unit) from full or partially filled fuel tanks:
- Already before starting work, switch on exhaust extraction system and place an extraction hose close to the sensor 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 air flow) with a displacement greater than 15 m 3 /h can be used.
- Prevent fuel from contacting skin! Wear fuel-resistant gloves!
