FUEL SUPPLY CIRCUIT CHECK
The fuel system is highly sensitive. The work must be carried out with the greatest cleanliness and care. Any air in the system could damage the high pressure fuel pump. The vehicle must therefore never be driven with the fuel tank empty.

|---|---|---|
| 1 | Check that the tank contains the correct type of fuel | Remove the contents and wash the tank |
