Yes, my reservoir does feed to my pump inlet. In the video, when I show the pump, the white wall it is mounted on is the reservoir, so the pump is at the same level as the res.
I actually figured it out, and you were correct - there was a big air bubble in the pump top between the pump and reservoir. I had to tilt the case completely onto its back to get the air bubbles out
Man, you are like a best answer machine, bro.
