fuel ?

Hello,
I am almost done with my s4 to s5 turbo II swap. My motor has a knight sports turbo. So I am starting on my fuel injectors and I am going with two 750cc and two 1000cc and I was wondering I will be using a haltech e8 and I want to use a adjustable fuel pressure regulator. I was wanting to know how some of you guys have hooked up a adjustable fuel pressure regulator to your stock fuel rails. Also if you have pictures of you modified fuel system I would like to see them.

SX / Aeromotive makes good quality FPRs with a diaphragm that acts as a pulsation damper.

Typical fuel system upgrade here:

(Despite what it says on that website, the stock 5/16" lines should really be replaced with 3/8" feed lines for anything much over 300hp. The Aeromotive catalog has a good planning section to help you choose components.)
