A system for reducing fuel slosh noise in a storage tank is described. In one particular example, the system comprises a slatted baffle with angularly arranged louvers extending therefrom to reduce sloshing noise in the tank by redirecting fuel waves while preventing surface wave collisions in the tank. In this way, the louvered baffle has the ability to provide different fuel flows based on the direction of flow incident on the slatted baffle, which may enhance the driving experience, particularly in hybrid and start-stop vehicles, where periods exist in the drive cycle where background engine noise is absent.
