If the petrol pump VAZ 2109 carburetor does not work correctly, it affects such an important process as the supply of fuel to the carburetor. Failures lead to a lack of fuel in this car node.
Now we will talk about such a procedure as the replacement of the fuel pump VAZ 2109. But, before starting the process itself - let's deal with the primary diagnosis. To find out the causes, perform the following steps:

A bit simpler than a Frenchman, but not bad. Some drivers install an electric petrol pump on a VAZ 2109 carburetor. Others prefer to install a carburetor with an automatic sub-pump on a VAZ 2109.
The procedure for disassembling the fuel pump and its replacement
- first you need to remove the air filter;
- after that the hose is removed, through which gasoline is fed to the fuel pump. To do this, loosen the clamp;
- the hose that feeds gasoline to the carburetor is removed in the same way;
- unscrew the nuts, fastening the fuel pump.
Remove it as carefully as possible, otherwise you can just ruin the gaskets. We investigate all the details for the presence of cracks and chips. Valves (intake and injection) are checked for leaks. We check the pipes too - they should not turn in their nests.
We look for the diaphragms to be in order - without damage and flaking fragments. Now we wash the parts with gasoline and blow air under pressure.
When you check all parts, you can begin to replace those that have already worn out, the pump gaskets are changed without fail. Worse, believe, from this neither you nor your car will not. During installation, Litol-24 grease is used.

If the distance is greater, the fuel pressure will be greater than necessary.
This, in turn, leads to malfunction of the check valve. When the distance is less than 0.8 mm, in situations where the car is traveling faster or experiencing increased loads, the fuel enters the carburetor in an amount that is not enough.
