FUEL HIGHWAY AND NOZZLES
Removal and installation
| PERFORMANCE ORDER |
| 1. Remove pressure in fuel system. Remove a weight wire from the accumulator. |
| 2. Remove the top section of an inlet collector. |
| 3. Disconnect electric sockets from four fuel nozzles and remove a plait of wires from the fuel highway. |
| 4. Unscrew connecting nuts and disconnect fuel hoses from the fuel highway. |
| 5. Unscrew three bolts and remove the fuel highway together with nozzles from an inlet collector. Remove the bottom sealing rings from fuel nozzles. |
| 6. Release brackets of fastening and take fuel nozzles from the fuel highway. Remove the top sealing rings from fuel nozzles. |
| 7. Installation is made in sequence, return to removal. Thus on fuel nozzles it is necessary to establish new sealing rings. |
|
PRESSURE REGULATOR
Removal and installation
| PERFORMANCE ORDER |
| 1. Remove pressure in fuel system and remove a weight wire from the accumulator. |
|
|
2. For improvement of access to the fuel highway remove an arm of a plait of wires from an inlet collector. On DOCH engines of 1,6 l the regulator of pressure settles down on the left forward end of the fuel highway. |
| 3. Holding a regulator a wrench, unscrew a connecting nut of a hose of supply of fuel. Disconnect a hose of supply of fuel and a vacuum hose from a regulator. |
| 4. Unscrew bolts and remove an arm of electric wires from the fuel highway. |
| 5. Remove a regulator from an end face of the fuel highway together with a sealing ring. |
| 6. Installation is made in sequence, return to removal. Thus it is necessary to use a new sealing ring. |
|
ENGINE OF MANAGEMENT OF IDLING TURNS
Removal and installation
| PERFORMANCE ORDER |
