What kind of electric fuel pumps are you all running on the street? I need something that will support 550 to 600 HP, I've looked at the Quick Fuel, wondering if it's a fancier Holley, never had no luck with the Holley blue. Then I got to thinking about the Carter 4600, Carters used to last forever. Haven't done the math yet to see how many GPH I need. Trying to findething that I won't need a return, one reason I was looking at the Carter, friend of mine just had to replace his, it was 25 yrs old!
