Help me decide on a plan for fuel system

I've already got a DC Power 185a alternator, XS D3400 battery, and 1/0 power and grounds, so electrical system is very stout.
I've read that since my truck is flex fuel, that the wiring to the pump is 10ga already. No way to verify this until I lift the bed, but assuming it is, can I use that for one 450 pump? Then run the second off new wire from the battery and use a Hobbs switch or some other device like a boost controller?

Looking for someone to help me with fuel injector heights and eBay rails
I bought a set of the Fasster -8an eBay rails for stock truck intakes. I assumed it would come with brackets to fit stock truck height injectors. Now, I believe my truck came with LS2 style injectors since its flex fuel, but you can see the pictures for how they fit.
I need to buy injectors for my turbo build, so the million dollar question is what type of injectors should I buy? Should I source truck length injectors with an EV6 connector or go for LS2 length ones and use a spacer? Keep in mind I will eventually put a Holley hi-ram on the truck with their rails, which I believe are for LS1 length? What length injectors would you guys order?

Injectors are typically measured oring to oring. Most of the GM ones are 48mm or 60mm, and injector spacers are typically available in 12mm (1/2") and 24mm (1"). Easiest thing for you to do for the moment is to measure that distance from the bracket to the rail and get on mcmaster carr and get some aluminum (or whatever material) spacers the exact height you need along with longer bolts. Use a micrometer to measure.

I'm just curious what type of injectors I should buy knowing what spacers and injector adapters are out there on the market. Are the truck style injectors 48mm and the LS1 60mm?

So after some more research, it looks like there are spacers that take an LS3 short injector to a truck height injector. This would allow me to buy LS3 injectors and use them in the rails I just bought for the stock intake, then when I get the hi ram, I can buy the LS3 to LS1 tall adapters and use the same injectors. What I'm trying to avoid is buying injectors twice, since the ones I'm looking at are around $700-$900
