That looks great. I was going to suggest what you did, use some old filter parts for a tight elbow. They are hard to find at a hardware store that are as small, especially with a tight radius.
Not being familiar with the sump part of the spec (seen a lot of them, never owned one), would it be possible to turn the pump sideways so you could run the tubing behind the back plastic? That would be really clean looking.
