The fuel pump (the carburettor engine)
| PERFORMANCE ORDER |
|
1. Disconnect the battery from weight, disconnect from the pump hoses, turn away 2 nuts of fastening of the pump. |
| 2. Remove the pump, if necessary displace the pump easy blow on wooden бруску. |
| 3. Remove 2 linings. |
| 4. The pump not folding and to repair is not subject. Installation is carried out upside-down. Replace linings from both parties of the prorate of the pump, without breaking their thickness. |
|
The fuel pump (инжекторный the engine)
The prevention In system of injection L-Jetronic the pumping pump is mounted near to a tank, in system Motronic this pump is mounted in a fuel tank. The gauge of level of fuel is mounted in a fuel tank on the pump of pumping or on the fuel pump.
| PERFORMANCE ORDER |
| Execute декомпрессию and disconnect the battery from weight. |
|
The fuel pump mounted out of a tank
| PERFORMANCE ORDER |
| 1. Lift the car. |
|
2. Remove a cover and disconnect from the wire pump. |
| 3. Press clips fuel hoses of the pump and disconnect them on the pump. |
| 4. Turn away screws of fastening and remove the pump. Installation is carried out upside-down. |
|
The fuel pump mounted in a tank (or the pumping pump)
| PERFORMANCE ORDER |
|
1. Turn away screws and remove лючок (is under a back seat or under a rug in a luggage carrier, depending on model). |
|
2. Disconnect sockets of the pump of pumping (1) and the gauge of level of fuel (2) in early system of injection Motronic. |
|
3. For a socket detachment hook скобу so that dredging was combined with a groove on a latch and dissolve socket parts. |
|
4. On a part of cars to take the pump with the gauge it is necessary to turn this knot counter-clockwise. |
|
5. On a part of cars the knot of the pump with the gauge fastens these nuts. |
|
|
| 6. In early system of injection Motronic at first get the gauge of level of fuel, then get the pump, without disconnecting hoses. |
| 7. On early models turn away fastening screws, take away скобы and remove the pumping pump. |
| 8. Installation is carried out upside-down. If necessary replace a lining between the pump and a fuel tank. |
|
The gauge of level of fuel
Conclusions of the gauge of level of fuel in late system Motronic
|
|
1. Weight of the gauge
2. To a control lamp
3. The gauge
4. Weight of the pump
5. The pump |
| PERFORMANCE ORDER |
| 1. Remove the pump with the gauge. |
|
2. In system of injection L-Jetronic and in early system Motronic check up resistance between the specified conclusions according to the table. Of late system Motronic be convinced that resistance between conclusions 1 and 3 decreases at a raising плунжера the gauge. |
| 3. If resistance differs, the gauge replace. |
| 4. Installation is carried out upside-down. |
