Removing fuel delivery line

WARNING: Working on 12 V electrical system.
Risk of short circuits! Risk of fire!

Make sure that there is no charger connected to the jump start terminal in the engine compartment.
Detach battery ground lead from battery.
For auxiliary batteries: Detach battery minus cables from all auxiliary batteries.

WARNING: Working on fuel system.
Risk of fire! Danger of explosion!

When working on the fuel system, make sure the workstation has sufficient ventilation, e.g., by means of extraction.
Tightly seal off open lines and connections; collect any leakage fuel directly at the point of exit.
No fire, sparks, open flames or smoking.

NOTE: RISK OF DAMAGE
Careless handling of tools and sharp-edged components.
Scratches, surface damage.

Protect working area.
Handle tools and components carefully.

NOTE: TECHNICAL INFORMATION
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.

NOTE: TECHNICAL INFORMATION
When the engine is stopped after the completion of trip, it may be necessary to run the electric fan. In rare cases, operation of the electric fan can last up to 11 min. This protects the components. In this case, replacing the electric fan will not remedy the problem!

When working on the fuel system, make sure the workstation has sufficient ventilation, e.g., by means of extraction.
Tightly seal off open lines and connections; collect any leakage fuel directly at the point of exit.
No fire, sparks, open flames or smoking.

CAUTION: On releasing high pressure line, fuel may emerge at high speed.
Injury hazard!

Wear suitable personal protective equipment.
Before performing any installation work, allow cooling system to cool down to less than 40°C.
Note warnings on cylinder head cover.

NOTE: RISK OF DAMAGE
Contaminant or foreign body.
Contamination can result in malfunctions, loss of function or leaks.

Adhere to the utmost cleanliness.
Protect components from contamination e.g. by covering.
Close off line connections with seal plugs.

NOTE: RISK OF DAMAGE
Damage to the ignition coil.
The silicone hose of the ignition coil must not be contaminated by fuel as this can lead to failure of the ignition coil.

When working on the fuel system, cover the ignition coils with suitable materials and remove where required.
Do not oil or grease the silicone tube of the spark plug socket. Do not use any protection or maintenance products (e.g. silicone spray, rubber care products, rust remover, etc.).

NOTE: TECHNICAL INFORMATION
