A float assembly according to an example of the present disclosure includes a guide extending in a first direction that has a stand-up and a shelf. A cover is oriented in a second direction substantially perpendicular to the first direction and welded to the stand-up at a weld joint. An undersurface of the cover abuts the shelf, and the abutment begins at a first distance in the second direction from the weld joint and ends at a second distance in the second direction from the weld joint.
