EFI fuel tank module for stock tanks

Yeah you won't need that. The fitec had its own regulator. Just need a standard EFI filter.

Also the the float on the ebody spectra may need a little tweak to reach full. I was messing with the one I have and it appears it contacts the spare tire cut out.

I understand that the fitech unit has a built in regulator, but I don't want to run another line the whole way for a return line. Using this, is no different than using the FCC currently. Inside the FCC is a return/pressure regulator, and there is only one line ran to the TBI. Mounting the GM filter/regulator closer to the tank accomplishes the same thing that is happening inside of the FCC without having the FCC take up room in your engine compartment and also get hot.
