fuel return placement

Unless you already have factory EFI on your EA81, it is doubtful that your current feed line will be big enough to flow enough fuel for the EA82T.
When Subaru put the EFI into the 85- models, they removed the carb return line, used the carb feed line as the return line, and then installed a bigger line again for the feed.
That sounds so weird that the return line needs to be bigger than the feed line for the regulator to work properly. Why would you need a bigger pipe when most of the fuel coming through the feed line is burnt in the engine, leaving less to go back?
Just becasue a line goes into the bottom of the tank from the outside doesn't mean it stays there once its inside the tank

ok, so I can't guarantee what I said about the lines then is accurate. I have no experience with carb turbos, only EFI, so my statements may or may not be relevant.
