Go big or??? Pump sizing

+ some kind of regulator (~$150), you are about $500 in ignoring plumbing which will be needed for either option.

Vaporworx module is $430, which just controls the pump.
Not sure what CTS-V fuel pump module assemblies are going for. OEM modules look to be ~$800, aftermarket about the same.
The Tanks Inc tank won't accept an OE style module so you will need to weld in the mounting ring, ~$200 in hardware + installation.
So now you're ~$1500 in. (unless I'm misinterpreting the Vaporworx site)

There is no arguing that the Vaporworx setup is better. Really depends on your intentions with the car as to whether its worth it.

The intentions with the car are 99% street/highway driving.
The other 1% will be AutoX and maybe occasional drag strip trips, with max performance in those areas not required. Just be for fun, not competition.

That's why I figured the 450LPH pump will be sufficient obviously, my main concern is whether it will be too much if I opt to run lower power levels initially. Just don't want to purchase two pump if one will do it with proper control.

+1 on one of Carl's VaporWorx controllers and a CTS-V pump module. I have that (boost referenced) feeding an E-Force blown 6.2L LS. A step up from that is replacing the GM pumps with DW pumps as another poster mentioned. The GM fuel pump buckets are good.

UGH!!!

All this new fangled EFI stuff I have to learn. Maybe I shoulda stuck with carbs

This is what I am running to support 750hp but I also have a tank like will69camaro with one side having a blank for the pump hat for future hp possibilities. I know pump size boosted vs n/a is different. Carl will direct you where you need to go. It is more straight forward than it might seem with Vaporworx.
