Many motorists are often faced with the problem of strong heating of the fuel pump at a speed of 95-100 km / h. As a result, the machine may stop altogether or display some malfunctions. There are several solutions to the problem, it all depends on the design of the car and the specific situation. But there are general recommendations that any motorist can use. The main thing is to know where the fuel pump is located and what operations can be performed with it.

One of the simplest solutions is to replace the fuel pump, but in practice this is often not a complete elimination of the problem. After all, for example, replacing a VAZ fuel pump costs a lot of money, but it can heat up as well as the previous one. In this case, repairing the fuel pump will help. However, you can fix it yourself if you find the cause of the problem. One of the reasons is a malfunction in the car's cooling system. Check all parts, clean parts if necessary. If there is a breakdown in the system itself, it must be replaced. Then, perhaps, the fuel pump will stop heating up. The reason for the heating of the fuel pump can also be its external damage, namely, wear of gears or rollers in volumetric hydraulic blowers, breakage or wear of the impeller in centrifugal ones. As a result, the temperature of the fuel pump rises, the dynamics of acceleration of the car decreases, and the engine power decreases. It is also very harmful to drive, as motorists say, with a "red light", that is, with a small amount of fuel in the tank. Especially at high temperatures outside. In this regard, the fuel pump overheats, the brush holder melts, as a result of which the brushes "hang" without touching the collector. Poor-quality fuel, which contains a lot of sulfur, has almost the same effect. Because of this, the collector gradually becomes covered with a dark coating, contact with the brushes deteriorates, as a result of which the brushes sparkle and the fuel pump overheats. It is also worth checking the condition of the main filter. Its clogging does not lead to the appearance of noise in the fuel pump, but also causes it to overheat and even fail. Finally, the car's gasoline pump can warm up due to short-term and often repeated contact faults in the power supply circuits, which may not appear externally, but because of them, the gas pump starts to work in the starting mode.
