Why is there a strong gasoline smell inside the car?

[StLilah]

Reasons for a strong gasoline smell inside the car: 1. Issues with the gasoline vapor canister (charcoal canister). Overfilling the fuel tank for extended periods can saturate the activated carbon in the canister, preventing timely reactivation. 2. Leakage at fuel pipe connections: If there's leakage at fuel pipe joints, gasoline odor may enter the cabin through the air conditioning system. Open the engine hood to check for leaks, and tighten connections or visit a repair shop if necessary. 3. Deterioration of rubber hoses: Rubber hoses in the engine compartment may degrade over time, especially in older vehicles, potentially causing gasoline leaks into the engine bay. The AC system could then draw these fumes into the cabin. 4. Incomplete fuel combustion: Unburned gasoline being expelled through the exhaust system.
