Fuel Supply System Safety Precautions

Fuel Supply System Safety Precautions

CAUTION!
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:

• Route lines of all types (e.g. for fuel, hydraulic, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.

• Ensure sufficient clearance to all moving or hot components.

• The fuel or fuel lines in fuel system can become very hot (danger of scalding)!

• In addition, the fuel system is under pressure! Before opening the system, place rags around the connection area and release pressure by carefully loosening the connection!

• Wear protective goggles and protective gloves when working on the fuel system!

Fuel pump is activated with switching on the ignition and by door contact switch of driver's door. Therefore for reasons of safety, connector - arrow - must be disconnected from fuel delivery unit before opening fuel supply system, if the battery is not disconnected.





Always observe the following when removing and installing the Fuel Level Sensor or the fuel pump (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 air flow) with a displacement greater than 15 m3/h can be used.

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