What Causes the Sound of Fuel Sloshing in the Fuel Tank While Driving?

[RileyMarie]

Liquid sloshing inside a moving container is a normal phenomenon, but if the sound of fuel sloshing in the fuel tank is loud enough to affect the driving or riding experience, it should not be ignored. Under normal circumstances, the sound of fuel sloshing should not be audible inside the car. Many similar cases actually have other underlying causes. The following are some possible explanations: Water Accumulation in the Door: For example, if the car is frequently targeted by small advertisements or often has cards inserted into the door, once water enters the door, these cards can turn into paper sludge, blocking the drainage holes on the inner side of the door. Water Accumulation in the Side Sill: For instance, the drainage outlets of the side sill may be blocked, or the protective adhesive tape over the drainage outlets may not have been removed. Water Accumulation in the Evaporator: If the air conditioning drainage outlet is blocked, it can cause water to accumulate in the evaporator.
