That's what I did and used a C5 corvette fuel tank transfer hose to connect it all.

I just used nylon fuel line with the proper quick connect ends and re plumbed it as needed (not modding any stock lines) instead of cutting the mounting tab. However I like how you cut that. I may re do mine then weld a filler on or screw/bolt a piece to reinforce the cut tab. I won't lie as of now my regulator/filter is fastened to the fuel rail with speed ties

for you guys that are doing this, are you running a -6 back to the tank and adding your own return fitting to the tank or top of the bucket?

Would this work with a NNBS with FPCM?

Heres my take on swapping a nnbs intake into a older return style truck. Granted not the cheapest route to take so most won't do it like this...

Used a set of the Holley rails, Magnafuel boost referenced regulator and -6 lines. This truck will be turbo but won't see but maybe 750 so -6 works fine for my setup. can always go bigger being the rails are -8. I ran my fuel lines to where they just plug right into the factory feed and return lines. Today the correct length spacers should come in and the last few pieces to the intake tomorrow so will hopefully have it installed soon.
