Hard to say. Some carb style regulators are not designed for a lot of inlet pressure. I've seen several of the cheap round chrome regulators fail with just stock mechanical pump pressures. I switched to Holley style and never had another failure, but I don't think even they are built for a lot of inlet pressure.

The main risk in doing it your way is that if your carb regulator fails, you will be sending very high pressure to the carb and will most likely have gas going everywhere. No guarantee that the Areomotive unit won't fail, but at least it's built to do what you need.
