Fuel Pump: Service Precautions
Safety Precautions
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
• Route lines of all types (for example, fuel, hydraulic, coolant, refrigerant, brake fluid and 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 for the fuel system can become very hot (danger of scalding)!
• In addition, the fuel system is under pressure! Before opening the system, place a cloth 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 fuel level sensor or the fuel delivery unit from a full or partially filled fuel tank:
When removing and installing the fuel level sensor from a full or partially full fuel tank, the following must be observed:
• Before starting work, switch on a exhaust extraction system and place an extraction hose close to the opening in the 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!
