Seem to have plenty of pressure but little flow from my shureflow and varistreem.... should I be able to see air in the strainer? would it work better with the sight glass underneath?

The strainer won't be full of water, there will be air space,

The water comes into the strainer and can travel all around it, then it has to go inside the strainer to the out-let section.
I think without a seal between the mesh and the clear plastic, particals may be able to get to the out-let and then into your pump, keep the clear section up right.

Oops I'll turn it back over.
