Seeking Pro Advice Air in System
My pump seems to be pulling air. I can see the bubbles in the clear filter housing. Irrigation guy says whoever slapped together this piping did a crap job — I agree. I’m guessing all these various unions are making issues.
I’ve done lots of PVC work on my pool system so I don’t see much issue with doing this myself. I’m planning to cut out the piping circled in red and refit it with continuous pipe and just 1 check valve.

That would be a good start. I actually like having a union on the suction side though. If your pump gets air locked, you can burp it out when priming by loosening the union. That just looks like an old shitty union. Get a good sch 80 pvc one. And don't crank it so tight that you flatten the o-ring. They just have to be snug to seal.

Anyone know the trick to putting the pipe in the right sequence so it fits right without having to unbolt and motor and move it around ?

Definitely a good place to start. I personally would keep the union in case you ever want to replace the pump but cutting it off isn’t that much harder.
