Is it normal for the fuel tank to buzz after the Lavida is turned off?

This is the sound of the fuel pump working, which is a normal phenomenon. Fuel pump: The fuel pump is a lightweight and compact pump, proposing a fuel pump and equipment with a housing made of aluminum-containing material. Inside this housing is a movable molded part, where this movable molded part is at least partially made of a sinterable, iron-based alloy material containing at least one austenite, and where the molded part made of a sinterable material has a thermal expansion coefficient that is at least 60% of the housing's thermal expansion coefficient. Vehicle pre-fuel supply: To ensure that the engine can ignite immediately upon starting, the vehicle must first store oil pressure, commonly known as pre-fuel supply for 3 seconds. The fuel pump in the tank continuously supplies fuel to the engine, hence the constant sound.
