Removal and installation

PERFORMANCE ORDER
1. Disconnect a wire of the minus plug of the accumulator.
2. Uncover the air filter.
3. Gradually turn off connection of a fuel tube on a fuel collector to release pressure and disconnect a tube.
4. Similarly disconnect the remained tubes.
5. Disconnect ventilating hoses from a cover of the valvate mechanism.
6. Disconnect a vacuum hose from the fuel pressure regulator.
7. Disconnect the socket of connection of the sensor of a stream of air. Remove a sealing ring.
8. Disconnect the socket of connection of the sensor of provision of a butterfly valve.
9. Disconnect an accelerator rope.
10. Remove a plait of wires from injectors, having squeezed fixing clips.
11. Turn off two fixing nuts (it is specified by an insole) and remove a fuel collector together with injectors.
12. For removal of an injector (a photo on the right) remove a fixing clip (a photo at the left).
13. If injectors are faulty, replace them.
14. Before installation replace sealing rings on injectors.
15. Installation is carried out upside-down removals.
