Default Fuel line configuration

Trying to finish up my swap and I am a bit confused on the fuel line routing/configuration.

The car is a 2001 L coupe with an 07 STi swap.

The OEM hard lines the exit the firewall @ the drivers side strut tower are what I need clarification on.

I know the bottom most line is the feed/pressure line, what I need to know is which of the other 2 (middle or top) is the return line?

On the 06 STi service manual I have, it shows:

Bottom line > FEED
Middle Line > EVAP
Top Line > RETURN

I need to know if the earlier Impreza's followed this same convention?

Can anyone point me in the right direction?
