Adjustable fuel pressure regulator help!!
I have a 1990 s5 turbo 2 motor and I’m looking into trying to do my own fuel set up. I bought a fuel pressure regulator off ebay 
I know its ebay crap. But I’ve been looking into how to set up the kit I got and I hit a wall I need someone’s help on how to go about installing it to the fuel rails, And what’s the easiest way to make it work? I already know you have to take the stock fuel pressure reg and cut it off. But do I need to do anything with the stock secondary fuel rail? Also I’m curious to what pressures people have there’s set to. I’m running 17psi right now stock inj any ideas? If you can maybe post pics on how you did yours that would be great please help and thank you.
