BTW: some of those mods will be installed at the same time as the AFPR. currently only have the intake and exhaust and walbro installed.

The stock fuel rail is fine. JBLMK3 sells a complete instalation kit including a mounting plate and the lines you will need to hook it up if you dont feel like sourcing the parts yourself.

i have no idea where you heard you need to upgrade your stock fuel rail. thats crap. you will need to bypass the J fitting on the return side tho- thats no big deal. if you get the jbl kit that will have everything you need.
i had basically the same setup you have except i had a 60 trim.
id start at 35 psi w/o vac line. tune on dyno w/ afc to get flat then adj fuel pressure to get the a/f where you want it. thats what i do and works well.

Depending on what size line you want to run(most run no#6) you will need a 12mm by 1.25 o-ring fitting(thread pitch of the hole left when removing the factory regulator) with the male size of the line you want to run ie. no#6 male to a male 12mm by 1.25 o-ring fitting, a fuel line( I use stainless braided line with a teflon inside liner), a fuel psi regulator, mounting bracket, and another fuel line to run to the factory return hose back to the tank.
