When you install the filter, besides mounting it upright, the fuel should enter from the bottom. This will move any air bubbles to the top, where they will get pushed through early in the start process.
If the fuel enters the filter from the top, where do the bubble(s) go? Air always rises.
I use the JetCat plumbing sequence:
UAT to fuel pump, fuel pump to filter, filter to solenoid valve, solenoid valve to ball valve, ball valve to turbine.
This way, any small particles of crud or brass from the fuel pump gear wear always goes through the filter before entering the solenoid valve..
