What Causes Occasional Gasoline Smell When Using Air Conditioning in the Car?

[ClaireDella]

Possible reasons for gasoline smell inside the car: Carbon canister rubber hose aging: This issue commonly occurs in older vehicles. Even the highest-quality rubber hoses in the engine compartment can deteriorate over time. Once aged, gasoline may leak into the engine compartment, allowing the air conditioning system to draw the odor into the cabin. Therefore, aged rubber hoses should be replaced promptly. Gasoline pipe joint leakage: Leaks sometimes occur at gasoline pipe joints, potentially allowing gasoline fumes to enter the cabin through the air conditioning system. If you detect gasoline smell in the car, inspect the gasoline pipe connections. This is easily visible upon opening the engine compartment cover, as prolonged leakage will form a layer of greasy residue on the surface. Recent fuel pump maintenance: If the fuel pump has been replaced or removed for repairs, residual substances left uncleaned after reassembly may cause gasoline odor. In such cases, simply verify proper fuel pump installation and clean any surrounding residues.
