  "textContent": "Methods and systems are provided for depressurizing a fuel tank of a vehicle by routing fuel tank vapors to an engine for combustion. In one example, a method may include reducing a pressure in the fuel tank by routing vapors from the fuel tank through a portion of a fuel vapor storage canister and, in response to an indication of a condition of degraded engine stability, re-routing the vapors from the fuel tank through an entirety of the fuel vapor storage canister. In this way, under conditions of degraded engine stability, a rate at which fuel tank vapors are directed to the engine may be reduced, which may thus mitigate the condition of degraded engine stability without aborting the operation to reduce the fuel tank pressure.",
