  "textContent": "Methods and systems are provided for purging a fuel vapor storage canister in an evaporative emissions system of a vehicle. In one example, a method may include generating vacuum in a fuel tank fluidically coupled to the fuel vapor storage canister during an auto-stop of an engine while the engine spins down to rest, and purging vapors to an intake manifold of the engine during a subsequent restart of the engine. In this way, the fuel tank may be held at a vacuum while the engine is off, enabling more efficient purging of the fuel vapor storage canister when the engine is restarted.",
