I'll be replacing the fuel line tomorrow, so count me in for reporting findings as well.
(My under-hood fuel lines were replaced with -6AN braided stainless ones, so swapping around is super easy.) Just have to figure out how to properly coil and secure that much hose.
Now, one interesting thing, is that in ATR, I'm only finding ONE load compensation table, not two like there appears to be in the GR STi ECU. Is this correct?
