Removal

Detachment of the electric socket from a fuel nozzle on system of injection of Multec fuel

Unscrewing of the screw of fastening of the holder of a fuel nozzle

PERFORMANCE ORDER
1. Take off pressure in fuel system.
2. Remove the heater block.
3. Remove a weight wire from the accumulator.
4. Disconnect the electric socket from a fuel nozzle (see rice. A detachment электричес whom the socket from a fuel nozzle on system of injection of Multec fuel).
5. Unscrew the screw, the fixing holder of a fuel nozzle to the top part of the case of a throttle. Remove the holder and a nozzle (see rice. Unscrewing of the screw of fastening of the holder of a fuel nozzle). Remove condense telny rings.

Installation

Arrangement of sealing rings on a fuel nozzle

PERFORMANCE ORDER
1. Installation is made in the sequence, the return to removal taking into account the next moments:

– at installation of a fuel nozzle use new sealing rings, for simplification of installation of a fuel nozzle grease sealing rings (see rice. An arrangement of sealing rings on a fuel nozzle);
– establish a fuel nozzle in such situation that the electric socket of a nozzle was directed to a back part of the car;
– before a vvinchivaniye of the screw of fastening of the holder of a fuel nozzle apply means on a screw carving, I interfere with a neck to unscrewing of the screw;
– include ignition and check fuel system for existence of leaks which need to be eliminated before start of the engine.
