Is the high fuel consumption of vehicles related to gasoline pumps?

The high fuel consumption of vehicles is also related to the gasoline pump. If there is something wrong with the fuel pump, it will pump less oil or more oil. Less engine oil will lead to insufficient internal combustion power and affect engine performance, while more engine oil will inevitably lead to engine oil waste:

1. The function of the automobile electric fuel pump is to suck the fuel out of the fuel tank, pressurize it and deliver it to the oil supply pipe, and cooperate with the fuel pressure regulator to establish a certain fuel pressure;

2. Ensure continuous fuel supply to the fuel injector;

3. The fuel pump is located in the fuel tank of the vehicle and works when the engine is started and running. If the engine is stopped and the ignition switch is still on, the HFM-SFI control module turns off the power of the fuel pump to avoid accidental ignition.
