How to diagnose a car's fuel system with a rubber glove

Any malfunction is easier to prevent than to fix. And therefore, from time to time, it makes sense to diagnose key components and assemblies of the car - in particular, the fuel system. But what if finances sing romances, and the car has not been checked for a long time? Go to the pharmacy and buy the simplest rubber gloves. And what to do with them next - read the material of the portal "AvtoVzglyad".

No wonder they say that it is better to trust car diagnostics to professionals who have the necessary knowledge, experience and equipment. However, the regulars of the forums, who are convinced that all servicemen are ignoramuses and scammers, dissuade other drivers from visiting the service station - they say, why feed the deceivers, if you can carry out many checks yourself. Including the fuel system.

So, what do the "experts" advise their "colleagues"? Armed with a medical glove, open the gas tank hatch and pull the rubber product over the neck. It’s good if you have electrical tape at hand - you can fasten a glove with it so that air doesn’t get inside, and the diagnostics show the true state of things. The next step is to start the engine and let it warm up for a couple of minutes.

Next, carefully inspect the glove pulled over the neck of the fuel tank - what happened to it in a few minutes? There may be several options: the rubber product swells, remains in its original position (that is, it dangles lifelessly), or it clogs inside. The authors of the “unique” technique say that it is possible to judge possible malfunctions of the system based on the state of the glove.

If the glove has retained its original appearance, it means that there are no deviations in the operation of the fuel system - you can sleep peacefully. A product filled with air in a matter of minutes indicates a malfunction of the pressure control mechanism - say, a regulator or fitting - or a clogged adsorber. Or about any other problems requiring urgent solutions.

For normal operation, the fuel system requires sufficient ventilation, in the absence of which a rarefaction of the atmosphere occurs. It, in turn, adversely affects the fuel pump, which pumps fuel with great difficulty. It is possible that you are faced with this misfortune if the glove is "sucked" inside. However, don’t rush to the service: perhaps, the “experts” write, everything is in order, after all, you unscrewed the lid for the experiment, and this greatly affects the result ...

But seriously, it is impossible to diagnose the fuel system of a car with a rubber glove. If you want to know its true state - without delay, go to the service. By the way, quite recently, the AvtoVzglyad portal tested a “folk” method for checking the condition of an engine using an ordinary coin. What came of it - read here.
