For protection of eyes against hit of fuel in them use points. At hit of fuel on skin wash out this place a plentiful amount of water.
Capacity in which there was a fuel contains vapors of fuel and is potentially explosive.
During the work with fuel system observe purity as the dirt which got to canals of fuel system can block them that will break normal operation of the engine.
Removal
Models with the only fuel pump
Arrangement of the fuel pump on models with the only pump
|
And – a connecting bolt;
In – electric sockets |
PERFORMANCE ORDER |
1. The fuel pump is installed under the bottom in a back part of the car. |
2. Take off pressure in fuel system. |
3. Remove a weight wire from the accumulator. |
4. Lift a back part of the car and record on supports. |
5. Unscrew screws and remove the protection cover of the fuel pump, the fuel filter and the accumulator of pressure (see rice. Unscrewing of screws of fastening of the protection cover of the fuel filter). |
6. Mark and disconnect electric sockets from the fuel pump (see rice. An arrangement of the fuel pump on models with the only pump). |
7. Using clips, press the fuel hoses connected to the fuel pump. |
8. Disconnect fuel-supply lines from the fuel pump. When using bayonetny connections remove sealing laying. |
9. Unscrew screws, take a fixing belt and remove the fuel pump from an arm. |

The arrow noted a belt of fastening of fuel pumps. |
PERFORMANCE ORDER |
1. On later models of an ustanavliv two identical fuel pumps yutsyatsya. Removal of fuel pumps is made similarly, as well as on models with the only fuel pump. At the same time it is necessary to consider that the second fuel pump is installed under the first, and they fasten the general belt (see rice. An arrangement of fuel pumps on models with two identical pumps). |

Models with primary and secondary fuel pumps
Arrangement of primary fuel pump
|
And – primary fuel pump;
In – rubber elements of fastening;
With – a differential case |
PERFORMANCE ORDER |
1. On later Station wagon models primary and secondary fuel pumps are installed. Removal of the secondary fuel pump is made similarly, as well as on models with the only fuel pump. |
2. Primary fuel pump by means of rubber elements fastens over a back part of a case of differential (see rice. Arrangement of primary fuel pump). |
3. Take off pressure in fuel system. |
4. Remove a weight wire from the accumulator. |
5. Lift a back part of the car and record on supports. |
6. Disconnect fixing belts and remove the protection cover of the fuel pump and an arm. |
7. Mark and disconnect electric sockets from the fuel pump. |
8. Using clips, press the fuel hoses connected to primary fuel pump. |
9. Disconnect fuel hoses from the fuel pump. When using bayonetny connections remove a sealing ring. |
10. Remove the fuel pump from rubber elements of fastenings. |

Installation
PERFORMANCE ORDER |
1. Installation is made in the sequence, the return to removal taking into account the next moments. |
2. Check that the fixing belt of the fuel pump is correctly established on the anticorrosive plastic isolating tube. |
3. In connections of bayonetny type establish new laying |
4. Start the engine and check that from the pipelines connected to the fuel pump there are no fuel leaks. |
