Location of AFPR and assorted fueling tidbits

[(NA)turalyRWD]

Alright i have purchased 20ft of braided stainless in both 6 abd 8 AN sizes for feed and return lines. I have a Mallory pump and 30-100psi AFPR along with a fuel cell.
Heres the Pump

and the AFPR

My understanding is that i need to run the AFPR at the end of the rail with the return headed back to the cell. The pump is external and will be mounted right at the tank where clearances provide. The questions i have pertain to the rail mainly, like what size threadings are on the ends so i know what adpaters to run. My other question is if i set the pressure back to stock nothing "should" change with the AFM correct? That tweakin will be saved for the dyno when its back up and running.

Thanks for the help

PPS 6 or 7m injectors any better for unrestricted and almost 10:1 static CR 5m?

Alright its a little unclear but basicaly i need to know what to do with the fuel once i get it into the engine bay. Like injectors and fuel rail fittings.

Thanks
