"Sunbathe" in the open field. Remember: before you completely “strike”, the motor became moody when driving and when starting up in a warmed state. And most importantly - gasoline consumption has increased markedly. N-yes, the carburetor is “buggy”. For example, a float is leaking (however, now such a case is a rarity) or the shutoff valve of the float chamber is leaking. Here the exit will require some qualifications …

However, if there was nothing like this in the medical history, and when you thought in the right direction, you found problems in the fuel supply, we proceed to the gasoline pump.

Let’s repeat the feed check - only not with the help of the starter, but with the lever for manual pumping of the fuel pump.

If petrol is supplied by hand normally, the nuts that secure the pump to the engine are likely to loosen. You need to take the key and tighten them tightly.

If gasoline does not come from manual pumping, you will have to loosen the clamp and remove the hose from the inlet fitting on the gasoline pump. Now, with sharp pressure on the swap lever, you can feel how air comes out from the end of the gas pipe that is disconnected from the carburetor. (By the way, the fuel pump creates very little pressure, therefore, when plugging the gas line, you should not force it with your hand; it is enough to close it with your finger moistened with saliva.) Does it not "puff"? The diagnosis is clear.

If it’s puffing properly, the obstacle in the way of gasoline must be sought earlier - in the line from the tank to the pump or in the tank itself.

Whatever your car, you will always get to the top of the gas tank. Inspect this part with an inquiring gaze - and you will see a tube on which a rubber hose of a gas pipeline is put on. Loosen the hose clamp and remove it from the tube. Then release the other end of the gas line - the one that fits the pump. Through a hose removed from the tube of the gas tank, purge the fuel line with a pump. If the air does not pass at all or goes with difficulty - this is bad, there is a hindrance. If it is blown easily - it is necessary to examine a gas tank.

What to look for in pipelines? Most likely, somewhere under the bottom of the car, the tube is damaged, crumpled due to a collision with a bump or from being hit by a stone that jumped out from under the wheel. If possible, inspect the machine from below: it is easy to notice such damage and at least roughly correct the dent with pliers. It is possible that a crack will appear on the rumpled pipe, from which gasoline oozes. It needs to be thickly covered with soap. Not a sealant, of course, but will allow you to safely get to the repair site.
