FiTech EFI system

I'd have to take a look under my car to verify, but yes, I have the factory unbaffled tank. I'm 99% sure the factory sender is still in place; however, I am unsure where the fuel line exits the tank.

But essentially what you are saying is to remove the current fuel lines and replace them with the kit above. Assuming I have 6AN line, I can use my current setup as a return line back to the tank, correct? Would I use the Holley Blue in the return line or just toss it?

You're looking good right up until you ask about keeping the blue.lol Yes, you take it off and don't use it.

Basically run the kit above, in place of what you have, and if you need MORE line than the kit supplies, and your line you took off is 6AN, then you can use some of it. yes.
