If you look carefully you'll notice the red and black hoses as they travel downward through the molded in opening in the lower center of the picture. If you look carefully you will see a bunch of brownish "fuzz" along the top edge of the cutout. What you are looking at are razor sharp fiberglass strands that are resinated and quite stiff, rubbing directly against the hoses. This view not only looks a bit messy, it is a spot where chafe on the hoses will occur over not too much time. Its a workmanship issue. Really sloppy workmanship. I don't know what runs through those hoses, and don't really care either. All I do know is that the hoses will fail long before their normal life expectency is reached because of chafe against this really sharp fiberglass edge.
