[QUOTE="Powerstroked162, post: 791638, member: 120"] The low pressure fuel system is regulated at 110-120psi to the cp4. I don't have flow ratings on the stock pump BUT I do know it flows a hefty amount. They designed the LP system to cool the HPFP as well as supply it. Pretty neat actually. What I'm interested in knowing is what the workable supply pressure for the cp4 is. Finding a aftermarket pump to handle 100+psi and live a long life is gonna be non-existent. That isn't from H&S though so it may not be right!..... LOL . [/QUOTE]
