The vents are part of the EVAP for when you fill up, the air displaced goes in to a charcoal canister, the fumes are absorbed and purged by intake vacuum to be re-burned instead of coming out in to the air we breathe, the fumes are a known carcinogen. Not like the old days when pump nozzles had no rubber boot and the displaced air/fumes came right out in your face. They can get clogged. The charcoal can get saturated if canister is not purged and liquid gasoline can back up in to them
