I bought a Boyd's tank from the vendor area on here. I was lucky enough to get in on this years group buy discount. Custom made to fit between the rear frame rails, fully welded .125 aluminum with 0-90ohm sending unit and aeromotive in tank efi fuel pump, The efi tank has extra baffling to keep the fuel at the pump head to keep constant pressure. Here are a couple links on here for the tank I am using.

It cost me about $600 but well worth it.
You will definately need an EFI fuel pump preferrably in tank but many people use Walbro in line pumps on a non baffled tank, just dont let it get below a 1/4 tank to keep constant fuel psi.
I don't know about emissions laws in Co but here we can get by with a lot. That being said most late efi swaps including LS based swaps will eliminate the rear two O2 sensors ( after that cat, and the cats for that matter) Then you will need to have your computer reflashed. If you do not have anyone local the street and performance is highly recommended for reprogramming.

Also on LT1swap.com there are ECM pinouts of our computer, Pinout=what all them wires go to.
Here is a link to that LT1swap.com page

That is about all my brain can dish out at the moment, and that should keep you busy for a little while
