In-tank fuel pump HotRodCity Garage aluminum gas tank help ?

I saw pics in the gen III hemi section, i think its map63vette, but couldnt find his post. I am doing a in tank pump for my hemi, and after seeing his pics, i want to upgrade from the factory tank with a rockvalley pump kit i already have. Those tanks look nice.

As far as with a carb, my understanding is you just need to have proper regulation, and return.
It would be A cleaner install than mounting one someplace else...
