Warning
|
|
The work involved in removing the fuel pipe requires working with the vehicle's fuel system. The following points should therefore be heeded in conjunction with these measures:
|
|
• Have a class BE fire extinguisher on hand! Be aware of the risk of sparks, i.e. in connection with electric circuits, short-circuiting, etc.
|
|
• Absolutely No Smoking!
|
|
• Ensure good ventilation! If there is approved ventilation for evacuating fuel fumes then this must be used.
|
|
• Wear protective gloves! Prolonged exposure of the hands to fuel can cause irritation to the skin.
|
|
• Wear protective goggles.

Be very thorough in terms of cleanliness when working in the fuel system. Malfunctions can also occur due to very small dirt particles. Prevent dirt from entering the fuel system by cleaning the hoses and plugging the pipes and lines upon removal using 93 161 370 Plug set. Store the components so that contaminants cannot enter.
