Is that the cheap flexible "bilge" pipe from the hardware store behind you tank connecting the overflows? If it is, a word of caution, I used that stuff and after about 2 years noticed it cracking apart in my sump where it was under water. When I went to remove and replace it it literally crumbled into little pieces........
Maybe you already replaced it and I just missed that post.
