What Are the Reasons for a Strong Gasoline Smell in a Car?

[DelMalia]

There are several main reasons for a strong gasoline smell in a car, which include: 1. Aging of the carbon canister rubber hoses. In 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. Residue during fuel pump removal or installation. The removal and installation of the fuel pump must be done inside the car, and some residue may inevitably remain during this process. If not cleaned properly, the smell of gasoline may be noticeable during use. 4. Overfilling the fuel tank. If the fuel tank is overfilled, gasoline may flow into the carbon canister through the pipes. The carbon canister, which is designed to collect gasoline vapors, may then release excess gasoline vapors through the ventilation holes. When the air conditioning is in the external circulation mode, the gasoline smell can enter the car.
