You can use the factory line for most of it. Cut off the flared ends and use a -6 a/n adapter (uses a crush type internal collet). Or just weld on the fittings.
I prefer to use teflon hose for the flexible connections as you don't get any fuel vapor smell from it. (and generally smaller outer diameter and looks nicer, in my opinion)
If you used the adapters and a return line could you tell me how many adapters you used?
