5.3 Return Setup and Routing Options I am looking for a little help with me 5.3.
I have a Carbureted L33 in my 81 caprice that I am in the process of swapping back to fuel injected.
I sourced an intake from a 2001 that has the return style fuel rails with the regulator.
My first question....are these the correct fitings I require to adapt -6 line?

My second question....I am running a Walbro 255lph pump. Is the oem regulator sufficient? Installed in the car right now, I have the Aeromotive Universal Bypass regulator with the low pressure spring (Regulator part number 13301), however, I have the high pressure spring for EFI applications. If I were to use this regulator....would I have to somehow disable the factory rail mounted unit? Or would I rather use it in conjunction with the oem piece?
I am very confused how to plumb my return regulator into return rails lol.
This is what the engine bay looked like before:
