Agreed on the peel ply and agreed on the pump. What altitude are you at? My Robinair 15500 will pull a full atmosphere but in at sea level. I can’t see your flow media but you can end it around 1 inch short of your layup or exactly at the edge. Anything beyond that is speeding up the resin for no reason.I’d also add 4 inches more to the distance from the layup to your vacuum line. Can almost avoid a resin trap that way.

Flow media to the edge of the laminate. 
I will try again at the weekend with a better pump and larger peel ply resin break.
I did think about placing the inlet resin spiral in between the 5 layers (just at the start)

I think it is your uni materials too.

You can add a layer of a woven cloth in between the uni layers to help the resin pass through better. 

Does anyone have a suggestion for the material/weight of the material to use in between layers?

Anything woven or stiched  as long as it creates a new feed path through in-between the uni layers.
