Reasons for Hearing Fuel Tank Sounds While Driving?

Door water accumulation, such as when the car is frequently targeted by small advertisements and often has cards inserted, can lead to these cards turning into paper pulp once water enters the door, thereby clogging the drainage holes on the inner side of the door. The following is an introduction to the fuel tank: Fuel tank: A container for storing fuel on airplanes or automobiles, specifically designed for storing hydraulic oil or hydraulic fluid in hydraulic systems. Precautions: Fuel tanks can be divided into two types: open tanks and closed tanks. The fuel tank must have a sufficiently large volume; the suction pipe and return pipe should be inserted below the minimum liquid level to prevent air suction and splashing of returning oil, which can create bubbles; the distance between the suction pipe and return pipe should be as far apart as possible, with a partition set between them; to maintain oil cleanliness, the fuel tank should have a sealed cover plate around the perimeter, equipped with an air filter; the bottom of the fuel tank should be at least 150mm above the ground; special attention should be paid to the anti-corrosion treatment of the inner surface of the fuel tank.
I remember always hearing a gurgling sound from the fuel tank when I first bought the car, especially during sharp turns or braking. Later, after consulting with car-savvy friends, I learned this is quite common in many vehicle models. The main reason is fuel movement – when accelerating, decelerating, or turning, the fuel sloshes and impacts the tank walls, creating a sound similar to shaking a water bottle. It's more noticeable when fuel levels are low because the empty space allows sound to reverberate more easily; when the tank is half-full or more, the sound usually becomes much quieter. Vehicle design also plays a role – for example, SUVs with higher ground clearance and poorer sound insulation tend to transmit these sounds into the cabin more easily. Additionally, it's important to check if the fuel pump is functioning properly. If the sound is accompanied by buzzing or knocking noises, it might indicate a faulty fuel pump or debris clogging the tank. However, in most cases it's harmless as long as you maintain adequate fuel levels. If the sound becomes unusually loud or is accompanied by strange odors, it's advisable to have it checked at a professional shop to prevent safety hazards. Regular maintenance like cleaning the fuel tank filter can help reduce these gurgling sounds.
