| q | 10 Nm |
| 6 - | Fuel pressure regulating valve -N276- |
| 7 - | High-pressure pump |
| 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 fitting the high pressure pump, take care that no dirt enters 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. |
| q | Removing and installing → Chapter |
| 8 - | Connection for the fuel return line to the fuel tank |
| q | Fuel pipe must be free of tension when installed (make sure all parts are clean) |
| 9 - | Fuel supply pipe to fuel rail |
| q | Tighten the connection hose to 30 Nm ( every time the fuel pipe is to be fitted, the hose torque must be verified) |
| q | Do not install fuel line under tension (observe maximum cleanliness). Tightening torque: 27 Nm. |
