info is a 347, 317s, t76, 18psi, dual walbros, -8 feed line, -6 return
i plan on making 750-800 i need a fuel pressure regulator but pennys are tight from this build already which one do i need without going way over board?
thanks for the help

Wow completly didn't even see that lol I guess that narrows that down but what justifys the hp rating? The 150 one says 700hp and the 230 one says 2000hp. 2000 seems like way over kill but the 700 isn't enough

The smaller unit has a -6 return... Likely the only difference. @ the 2K level,[-8 return] there would obviously be a bigger supply side, [BMF pump[]s], where the 700 unit may not have sufficient return flow w/ a -6.
FWIW, I run -8 supply, and -6 return on my Buick @ about 850FWHP... No control problem[s].
You say U R using a -6 return. Are the Walbro's run w/ a Hobbs sw, so only 1 runs at low/no boost? If so, the the -6 line will handle the return volume, NP.
I use the " psi test" for the regulator and return line. I set the reg at op pressure, then see if I can turn the psi down at least 5psi. If so, all's well. If not, then there's a return side problem to be resolved.
