I started playing with the surge device some more and it will run without a pump if you offset the two siphon breaks more. By placing a piece of PVC in the main opening you increase the distance between the main siphon break and the barb fitting. This allows the barb fitting to start drawing air sooner which means that it will fully break the siphon and create the surge you are looking for.

Now it's a solid-state, self regulating surge device.
