There is a member, stock48, running same setup. I've been contemplating to do the same setup for long. I have aero 340 intank and it's doing good job at my hp level.

around how much fuel pressure would you need need to keep up with the boost?

does anyone know of a after market regulator that would hook up to factory return lines on 2002 chevy?

i did this same thing. I drilled a hole in the rear of the tank, ran a line up to my "custom" fuel rail crossover. I cut an inlet off another fuel rail and welded it into the stock crossover. Second pump runs off a hobbs switch and stock regulator works fine. Fuel pressure is consistent and rises 1:1 with boost. Works great! Been that way for 3 or 4 years now.

Did you just drill a hole in the bottom or run a rear sump? Any pictures of this?

Drilled a hole in the rear. The pump only runs when I'm above 5psi, and the back of the tank is where all the fuel will always be at that point. I could take a pic sometime if you want. Think I tapped the hole for 3/4 pipe and used some epoxy also. Never leaked or had any issues.
