A crop sprayer comprises a main frame including a first elongated frame rail and a second elongated frame rail that are spaced apart from each other. A first elongated tank support is secured in fixed relation to the first elongated frame rail and includes a first elongated convex support surface. A second elongated tank support is secured in fixed relation to second elongated frame rail and includes a second elongated convex support surface. The second elongated tank support is spaced apart from the first elongated tank support to define a sump space therebetween. The crop sprayer includes a product tank defining a first cavity that is configured to contain a first quantity of fluid therein. The product tank includes i) a first elongated concave support surface, and ii) a second elongated concave support surface. The first elongated convex support surface is positioned in mating contact with the first elongated concave support surface. The second elongated convex support surface is positioned in mating contact with the second elongated concave support surface. The first elongated concave support surface and second elongated concave support surface define a product sump portion of the product tank. The product sump portion is at least partially positioned in the sump space.
