Disassembled the booster pump last night. O-ring looks good, no clogs in impeller. Re-assembled, and for grins replaced the input hose. Most of the cloudiness is gone. Still getting some air, but I think I am on the right track. I do have a slight water leak in a fitting before the booster pump. I will presume that is where the air is getting in. It will be the weekend before I can dig into repairing that.

Thanks for the advice.

I do have a "cloudy" issue, but I will submit a second post on that one.
