Safety Precautions When Working on Fuel Supply System

Safety Precautions When Working On Fuel Supply System

CAUTION: When doing any repair work, especially in the engine compartment, due to the cramped conditions, pay attention to the following:
- Route all sorts of lines (e.g. for fuel, hydraulics, evaporative emissions system, coolant, refrigerant, brake fluid and vacuum lines and hoses) and electrical wiring so that the original positions are restored.
- Make sure sufficient clearance to all moving or hot components.

When removing and installing the fuel gauge sender or fuel pump (fuel delivery unit) from a full or partly full fuel tank the following must be observed:

WARNING: Fuel supply lines are under pressure! Before removing from hose connection wrap a cloth around the connection. Then release pressure by carefully pulling hose off connection.

- Before commencing work, switch on exhaust extraction system and place an extraction hose close to the sender 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 cu.m/h can be used.

- Prevent skin contact with fuel! Wear fuel-resistant gloves.







- For safety reasons, remove fuse 28 from fuse holder before opening fuel system because fuel pump can be activated via driver side door contact switch.
