Been there, done that, didn’t work. My engines did not flood but they could not be tuned to run with the same top end they had before change.

I would and have simply put two 12oz tanks in the center to isolate the two systems. More complex solutions exist which I have not tried.

To complicate matters an 8oz tank is usually adequate for a 46 and 12oz will sometimes create fuel draw problems in a single engine application.
