To begin with, I’ll say “Yes” twice: -Yes, this is another post about yet another installation of an EBN on a carburetor car, of which there are a dime a dozen here. But why am I worse? -Yes, the Pekar pump is not a plunger pump. It’s an ordinary diaphragm pump. Few people have seen plunger fuel pumps on VAZ.
So, it all started (and subsequently ended successfully) with the fact that a friend in his “nine” got the standard problem of all “chisels” in the heat - the fuel pump located high above the engine, due to overheating in the summer heat, stopped pumping due to excessive different thermal expansion of the valves themselves and their seats. The car “stupided” and stalled while driving. The solution was (temporarily) only by wrapping the pump with a rag, followed by abundant wetting with water. Only under such a “cool” compress did the pump agree to supply us with gasoline. The solution came naturally - to replace the mechanical fuel pump with an electric, low-pressure one. The low-pressure electric pump pumps gasoline into the carburetor at a working pressure of 1 atm. The maximum possible pressure with the outlet line completely closed (the needle is closed, there is no return) is 3 atm. The pump was purchased for 480 UAH in my city + standard 4-pin relay + relay socket. Then it was a small task - install it and connect the electrical part. Installation, pulling wires, crimping terminals and connecting took about 30 minutes. The pump itself was placed bluntly in the “cut” of the standard pump, and secured to it with a bracket that came with the kit. The old pump did not turn off (the rod was not removed), and it works if it is not overheated
