Fuel line solution for NA to WRX swap

[Muffin15]

Hey all!

I'll be swapping a full STI longblock with all 2006 WRX supporting bits (electrical, turbo, brakes, etc..) into my 06 NA real soon here. The WRXs have the third hard fuel line in the cabin that NAs do not, I believe the high pressure return from the rails. What have people done to add a third line? I've had no luck searching threads, unfortunately.

Options I've thought of:
1) Buying new fuel hard lines for the cabin, but these do not seem to be available on rockauto. I suspect these are near-impossible to remove/install without damaging, either, as it looks like something that's installed before the shell is completely assembled.

2) Doing up some braided 6-an lines/fittings, which seems perfectly doable, but not without also buying an aftermarket fuel rail to allow the lines to mate up with the rail lines

Any thoughts? I'm prepared to purchase rails and 6-an lines/fittings but just curious if anyone else has had any other solutions. I'm a bit skeptical of the durability lines sourced from advanced or o'reilly's

If you have the tank dropped and most interior out, it's not that bad.
I did a similar swap into an 07 impreza sedan from a 04 wrx wagon.

Have you gotten to the wiring part yet of it?

This week has been devoted to tear-down and installation. I opted to just order the additional return line from Subaru as the OEM part is only about $50. Was hoping to salvage the line from the donor shell but the ends where the exit the body are too crusty for me to feel good about. All wiring is swapped except for the harness that goes over the tank and to the charcoal canister! Dropping the tank today to do that last bit

What did you end up doing? I am swapping a 04 xt engine into an 06 impreza and i am having this same problem with that 3rd fuel line and wondering what i need to do.

Thanks!
