hey everyone, I'm getting ready to purchase a fuel system. My setup is a d1x procharger and cenrti cam. I'm pretty set on fore innovations dual pump with -8 feed and return. my question is do I get the system with the fuel rails routed in series and the regulator after the rails? Or do I get the system with the fuel rails routed in parallel and the regulator before the rails? Also wondering if I should get the FC2 or FC3 controller. Any advice from someone with experience is greatly appreciated,
