What Causes a Strong Gasoline Smell in Cars?

[Herb]

Car gasoline smell may be due to aging rubber hoses of the carbon canister. In cars with high mileage, rubber components in the engine compartment are prone to aging. Here is some related information about strong gasoline smells: 1. Gasoline pipe leakage: If there is indeed a leakage in the gasoline pipe, gasoline may enter the car through the air conditioning system. Leakage usually occurs at the joints between pipes. 2. Overfilling the fuel tank: If the fuel tank is overfilled, gasoline may flow into the carbon canister through the pipes. The carbon canister, originally designed to collect gasoline vapors, will release excess gasoline vapors from the vent when invaded by liquid gasoline. When the air conditioning is in the external circulation mode, the gasoline smell can enter the car.
