I dont remember the exact model because I didnt buy it, this was a lucky local find. Guy had a turbo LS 68 Camaro that he was parting out. So the pump is way overkill for me. It was made to support like 700 boosted HP, which means its good for like 900 NA.
Im using the fixed Holley regulator and filter in one setup. Its not adjustable, it sets you at ~60 psi and thats what you get. I have a 1/2 stainless line that runs most of the length of the car. -8 AN line in the engine bay and making up the short return system from the filter/regulator. A couple of very short pieces of injection pressure-rated rubber as jumpers here and there.
On the "why is this better" part of it. It might technically be "better" to have the regulator closer to the carb, but considering so may of the OEMs do it the other way I gotta think better is a relative term. One that can be over-ruled by the convenience of not putting all the extra fuel line in.
