New Quick Fuel carb

If you have a stock style mechanical fuel pump, you will probably need to get an adapter for the pump outlet to convert it from 5/16 inverted flare to 6 AN; this one or similar http://www.summitracing.com/parts/ear-991946erl

To adapt the carb inlet to 6 AN you would need this one or similar http://www.summitracing.com/parts/ear-at991942erl/overview/ You can probably find other brands (like summit or jegs) that perform the same function.

I'm looking into some of this stuff, too, since I'm planning swapping carbs and rerouting my fuel lines a little, and it looks to me like much of the premade stuff assumes you have an aftermarket pump with the various inlet sizes.

I'm not sure if there is a way to convert an existing hardline to an AN fitting. I haven't tried to find fittings for that.
