Im building a 300 with a blow thru carb and an electric fuel pump in a fuel cell. I understand I must run a boost reference fpr im assuming set at 7psi my question is I've noticed some guys run two fuel pressure regulater set at 10psi before and after the carb is this neseccery or what is the theory behind it. I will be running a return style system with a 90 psi pump
