Is it related to temperature that gasoline engines can't pump oil?

In hot weather, the failure rate of gasoline pump is high.

The failure rate of gasoline pump in summer will be higher than that in winter, mainly because of the high temperature and the easy generation of fuel vapor in the fuel tank, which leads to the "gas resistance" problem of gasoline pump.

At present, most manufacturers add activated carbon to gasoline pumps to help the secondary utilization of fuel vapor and try to avoid the occurrence of gas resistance problems.

There is always a shortage of oil, and the gasoline pump is easily damaged.

It is easy to damage the gasoline pump when the fuel tank light is on before refueling. Because when the fuel indicator gives an alarm, there is only a small amount of fuel in the tank. If you don't refuel in time, the motor part will not be cooled and lubricated. Occasionally, once or twice, the oil meter light will alarm to refuel, which will not have much impact on the gasoline pump, but if it is done frequently, it will cause premature damage to the oil pump motor.
