Update:
I re-ran the hoses to the pump so that they went up above the LQ. Both the valve and the flow meter are now above the LQ. I had to add about 2 feet more of hose in order to do this (replaced a smaller section between the flow meter and the check valve). This had a negative effect on my flow. Now I am hardly getting any flow, even with the valve fully open. I even removed the check valve, but it made no difference.
Decided to check and see if the LQ would still drain into the pump, even though the hose ran above it. I used some old OTO that I had to to color the water. I squeezed a bunch right by the outlet valve which turned the water brown. I could see it in the tube heading up to the valve. I then shut the pump off. The flow of the water slowed down, but it was still moving toward the pump. This tells me that no matter where the hose is, you can still get a siphon effect. I'm sure if I left the pump off long enough, it would eventually drain down to the outlet valve, and then let air in line.
So I've decided to get rid of the LQ. Its been a frustrating experience to say the least. I'm only happy that I chose not to drill holes in my lines.
