New Rails... Stock System... Well i purchased aftermarket rails and the all the Nickel Plated AN fittings i would need for the job.. however, my question is how to regulate the pressure using the stock regulator or if that is even possible.
I guess what i am looking for is a layout of the stock system and the wiring that goes to the system near the rail.
All i am looking to do is replace the fuel system from the hardline forward.

I know its not adjustable... I am trying to figure out what i need to keep/how to keep it. with new rails. It appears there is some electrical equipment (sensor maybe?) that the fuel is feeding into as well. How do i go about incorporating or removing this.. there seems to be wires going to it as well.

You don't need anything else for them to work. That silver ring bulbous structure on the rail is a pulse dampner to equalize fuel pulses b/w rails but it's done away with when going to aftermarket rails.

I just finished changing the FPR on an LT1 and figured that was the regulator as well.. they look very similar.
Also... Where do the other fuel lines go.. there is a pack of 3 or so and only one goes to the rails. Or are they not fuel lines? they are all wrapped together.

The line that is positioned next to the main feed line is the fuel evap line that goes to the evap canister. It vents the tank and the vapors are sucked back into the intake. You can remove it and vent to the atmosphere(not a good idea if you've got a visual inspection of the engine bay)or relocate it elsewhere w/a little creativity. I relocated mine to the front of the ABS block to clean up the valve covers when I did aftermarket rails and the coil pack re-lo mod.
