What would happen if you run the return off of the schrader valve from the stock fuel rails with no regulator? I am just curious because I have seen a car set-up like this before. He had an intank and inline fuel pump and routed the return off of the test port. I thought it was a bad idea but hey I am still routing everything through my ATI FMU that is no longer boost referenced. I just have it tuned to run off of the Racetronix PnP and 60 lb injectors.

and if you have no regulator your will have extremely poor fuel pressure and most likely an extremely tough time making anything useful out of it.
the fmu is a pressure regulator, but it just does it on a ratio and is put ahead of the stock regulator to supercede it.

I think my fuel system is what you describe. I simply removed the shrader from the test port, screwed on a fuel regulator then ran a line to the back of the car to the return. I run dual walbs in the tank.
Really easy and inexpensive to do.
I've been running this setup at the below power level, daily driven during the warm season for the last 3 or 4 years. No problems so far.

I used an aeromotive regulator....I don't know which one. Probably about 1x2" in size. I screwed it right onto the fuel rail.
I used a steel braided line, but not the one from the ATI kit. I went and purchased a rubber lined 6an steel braided line. I ran the line right next to the stock supply line all the way back to the factory return line and joined the two.
My only regret is not getting the teflon lined steel braided line....for some odd reason the rubber lined hose smells like fuel even when there are no leaks. Kind of annoying.
