USAF 98 GSX

Background info: 98 GSX, all maintenance completed, minor mods (Intake, exhaust, DSM Link v3 and FMIC), everything else on car is stock.

Future goals: 500-600hp, E85.

Road to goal: I started my journey by completing the most important thing when buying a used car. ALL Maintenance costs and repairs. Car came with FMIC installed when I bought it, I installed intake, test-pipe (removed cat) and the bought DSM Link v3. I recently bought a beautiful rebuilt 14b and Ive decided its time to start my journey with supporting mods. I would like to first start with my fuel system. I would like to have an in-tank 255, in-line 255, full nylon braid fuel line to filter, new filter assy, braided line to rail, upgraded fuel rail, braided line to FPR, upgraded FPR, and a fully braided return line to tank. (I'm honestly not even sure if thats the correct route of fuel lines and components):confused:
I will also be installing 1600cc injectors with all of these parts.

Questions:

With my high HP goal, can I use 8 AN lines all around? Even the return line? (Or is the return line always supposed to be smaller?)

Should I use two 255lph pumps or one 455lph pump?

Believe it or not the fuel system on a DSM is one of the few systems I know very little about. To be honest, I am actually unsure the route of fuel lines and fuel components. I have drawn a simple diagram using Paint which shows what I think is the correct way the fuel flows through our vehicles. Go ahead a laugh. Lol.

Any advice, tips, corrections and comments would be greatly appreciated. I tried to include everything you might need to know to help me out. Thank you in advance!
