摘要: Methods and systems are provided for vehicle fuel tanks including multiple reservoirs. In one example, a method may include opening a canister purge valve of a fuel system responsive to a fuel level of a fuel tank transitioning above a first threshold fuel level, and closing the canister purge valve after flowing a pre-determined amount of fuel to the fuel tank while the canister purge valve is open.
