Instructions for replacing a fuel pump with a VAZ 2107
It happens with many drivers that when driving, their VAZ 2107 begins to twitch and the fuel into the carburetor seems to get jerky. Most likely, the reason for this problem is precisely the failure of the fuel pump. In most cases, this part is not repaired at all, but they are trying to replace it with a new one.
Pay attention to the list of the necessary tools that you need for this type of repair:
- socket head 13 mm
- small extension - no more than 10 cm
- ratchet (for more comfortable operation)
- Two screwdrivers: both flat and cross-bladed
To relieve the pressure in the fuel system before starting work, it is necessary to disconnect the petrol hose suitable for the pump and lift it up so that fuel does not leak out. Then start the engine and wait until it spontaneously stalls, that is, all the fuel is used up. Then you can proceed further.
So, we loosen all the clamps of the suitable fuel hoses:
And we pull them off with a little effort:
It remains to unscrew two nuts, one on each side, with which the pump is attached to the cylinder block of the VAZ 2107:
When the nuts are completely unscrewed, the fuel pump can be carefully removed, with medium effort moving it to the side from the studs. It is clearly shown in the photo:
Installation is carried out in the reverse order of removal. Remember to reconnect all fuel hoses that were removed before. The price of a new part is about 300 rubles, although some models with two valves (chambers) cost twice as much.
