What Causes the Smell of Gasoline Inside the Car After Refueling?
2 Answers
When the gasoline is filled too full, it may flow into the carbon canister through the fuel line. Once the carbon canister is soaked with gasoline, it may excessively release gasoline vapors through the ventilation holes. Below is relevant information about gasoline: 1. Precautions for refueling: Use automotive gasoline; avoid using gasoline containing methanol or alcohol; do not spill fuel on the paint surface to prevent damage; prevent fuel injection due to excessive fuel pressure. 2. Solution: Set the air conditioning to internal circulation mode, drive for a while to allow the gasoline to be naturally consumed, and the gasoline smell will gradually disappear.
I just fixed a car with this exact issue, and the owner also smelled gasoline after refueling. It's mostly because the fuel nozzle wasn't inserted properly during refueling, or the tank was overfilled. When gasoline overflows from the tank opening, the evaporating fuel vapors can enter the cabin through gaps in the chassis. Additionally, a loose fuel cap or a deteriorated seal can cause leaks, especially common in older vehicles. If the charcoal canister is clogged or faulty, gasoline vapors can't be absorbed and will escape directly. After refueling, always check if the fuel cap is tightened properly and avoid overfilling to prevent spills. If the smell persists, promptly inspect the charcoal canister and fuel lines.
