What Causes the Smell of Gasoline in the Air Blown by the Car Air Conditioner?

[RhettLee]

Car air conditioner blowing air with a gasoline smell may be caused by leaks at the gasoline pipe connections or overfilling the fuel tank. Gasoline pipe leakage: The smell of gasoline may enter the car through the air conditioning system. Leaks usually occur at the connections between pipes. Open the engine compartment cover and visually inspect, as leaks will eventually leave a layer of oily residue on the surface over time. Tightening or repair is needed. Overfilling the fuel tank: Overfilling the tank can easily cause a gasoline smell inside the car. If gasoline enters the pipes in the activated carbon canister system, these liquid fuels not only harm the carbon canister itself but can also flow into the intake manifold, causing spark plug flooding. This can lead to serious consequences such as the car stalling when refueling and eventually failing to start.
