Fuel Supply System

Fuel Supply System

The fuel lines are under pressure.

Danger of personal injury to eyes and skin.

Wear protective eyewear and protective clothing in order to avoid injury and contact with the skin. Wrap a cloth around the connection before removing a fuel hose. Open the connection carefully and release the pressure.

For safety reasons, interrupt the current to the fuel pump before opening the fuel system. Otherwise, the fuel pump will activate when the drivers door opens or when the ignition is turned on. It is possible to interrupt the current flow by using one of the following possibilities:

• Disconnecting the battery

or

• Removing the fuel pump fuse

or

• Disconnecting the connector on the fuel delivery unit flange

Note the following whenever working inside the engine compartment due to limited space:

• Route all lines and wires in their original locations.

• Ensure sufficient clearance to all moving or hot components.

Always observe the following when removing and installing the fuel level sensor or the fuel pump from a full or partially filled fuel tank.

• Before starting work, switch the exhaust extraction system on and place an extraction hose close to the fuel tank opening to extract the fuel fumes. If no exhaust extraction system is available, a radial fan (as long as the motor is not in the air flow) with a displacement greater than 15 m3/h can be used.

• Prevent fuel from contacting skin! Wear fuel resistant gloves!
