If each elbow equals 1ft of head that makes 14 feet of head. The pump shuts off at 12'. So this won't work will it?

Another thought, if I use that flex hose there won't be any elbows, will that work better?

First, it is 12' of "head" that the pump stops working at, NOT 12' of pipe, and the frictional losses depend heavily on the pipe size. 1.5" pipe is more than enough for a dart.
Second, are you counting each output elbow of the sea swirl as a inline elbow. You should be counting each elbow in the "path" to the tank.

IE: if your return splits into 8 lines and each has an elbow, you really only have 1 elbow between the pump and the tank.

BTW: I had a dart, and now a snapper and I do love those pumps.
