It always sounds scary to have exposed electrical stuff inside a gas tank, but what I did by connecting the wiper to the ground directly via a wire should be even safer than having the loose connection on the pivot that could theoretically spark. As it is, every fuel sender has the resistance element that the slider slides against, which is much more like a "filament", than a 20-gage stranded copper wire is. The fuel gage itself must limit the current to a value that can't generate a spark no matter what goes wrong with the sender, since I've never heard of a fuel tank blowing up due to a spark caused by the sender.
