Fuel Pump: Service Precautions

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, additive, 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!

Always observe the following when removing and installing the sender for fuel gauge or the fuel delivery unit from full or partially filled fuel tanks:

When removing and installing sender for fuel gauge from full or partially full fuel tanks, the following must be observed:

• 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!
