Why Is There a Suction Sound When Opening the Fuel Tank Cap?

The reason for the suction sound when opening the fuel tank cap: It may be due to a malfunction in the carbon canister or solenoid valve, causing the pressure inside the fuel tank to be lower than the external pressure, resulting in the suction sound. If it is only heard occasionally, it is a normal phenomenon; if the sound is frequently heard, it is necessary to promptly check and repair at an auto repair shop. The following are symptoms of a damaged carbon canister: 1. The fuel nozzle jumps when refueling, or gas is ejected when opening the fuel tank cap. 2. Fuel vapor or dripping oil appears at the atmospheric outlet of the carbon canister; or when the carbon canister is removed, it is found to be filled with gasoline. 3. Poor acceleration, jerking, or unstable idle speed. 4. Engine stalling and failure to start, or unusual noises while driving.
