you need to place that Cartech unit inline with the aeromotive regulator in the return line. The way you have it pictured in your pic is in parrallel. That just won't work. When the cartech unit is trying to add fuel pressure, the aeromotive unit is just bypassing the fuel to return.
The only way the setup will work is if you place the cartech's inlet directly from the aeromotive's outlet to the return (bottom port). Then run the cartech's outlet to the fuel return back to the tank.

P.S. good luck setting up a 2025 unit. I believe that particular unit is for N/A motors getting turbo added to them. The one you should have purchased only had the bleed adjustment without the center base pressure adjustment (2022 unit).
