What Causes a Strong Gasoline Smell?

[VanKingston]

Car gasoline smell is heavy, there are the following reasons: 1. Carbon canister rubber hose aging: For cars with high mileage, rubber components in the engine compartment are prone to aging. 2. Gasoline pipe leakage: If there is a leak in the gasoline pipe, the smell of gasoline may enter the car through the air conditioning system. 3. Residual gasoline during fuel pump installation: The installation of the fuel pump must be done inside the car, and during this process, some residue is inevitable. If not cleaned properly, the smell of gasoline may be noticed during use. 4. Overfilling of gasoline: If the gasoline is overfilled, it may flow into the carbon canister through the pipes. The carbon canister, originally used to collect gasoline vapor, will release excess gasoline vapor from the vent when filled with gasoline. When the air conditioning is in the external circulation mode, the gasoline smell enters the car.
