Information
- The ignition must be switched off when working on the fuel system.
- Absorb any escaping fuel using a suitable binding material or a cloth.
- Cloths which have absorbed fuel must be disposed of according to the applicable national laws.
- The fuel system must be depressurized before starting work on it.
- Only work on the fuel system in well-ventilated rooms.
- Any seals which have been removed must always be replaced.
- Pull off plug connection for the fuel pressure sensor.
- Place a cloth under the pressure sensor and remove the pressure sensor slowly using a long socket or a similar tool (a/f 24 mm). Relieve the fuel pressure by slowly opening the pressure sensor.
- Visually check the thread and sealing ball to make sure they are not damaged.
