For my 72 with a LQ9 swap I ran hard line with 3/8 compression to AN fitting on either end to adapt to a short AN flex line. I heard stories of AN line weeping fuel after time.
For my 78 2wd blazer I used all OEM style nylon line. 3/8 feed and 5/16 return. I used brass fitting at the 87+ EFI tank module. I added a 1996 Impala SS inline fuel filter on the frame rail with OEM quick disconnects. I adapted to EFI rubber hose between the carb and the bypass regulator but that was specific to my application. You can run it all the way to the intake. You should have a fuel pressure regulator at the fuel rail if it had a return line. Just add some heat protection on the nylon line if it runs near exhaust/headers.
