q | With fuel pressure regulating valve -N276- and fuel pressure sender, low pressure -G410- |
q | In the fuel tank there is an electric fuel pump which sends fuel with a pressure of around 6 bar to the high pressure pump. |
q | When installing the high-pressure fuel pump, it is essential to ensure that no dirt particles enter the fuel system |
q | The fuel pump must be absolutely pressureless; reduce the fuel pressure. → Chapter |
q | The fuel lines must be laid free of stress. |
