Trying to get some ideas for the fuel system in my pulling truck so I can do some shopping over the winter. The motor is a 470cu RB with a single 4bbl. Would like to see 700hp out of the motor, but won't know until it hits the dyno. Plan on spinning the motor around 7500 at upwards to 20 seconds a pull. I'll be starting from scratch on the fuel system with a fuel cell behind the cab. My guess is that if the system is adequate for the motor the constant high rpm wouldn't matter, but also wondered if the rpm drop in a car while shifting during a race might give the pump a small window to catch up to the demands of the engine.
So, what would some of you guys recommend for a fuel system?
I use theAeromotive 2000 pump with there matching regulator and there electronic speed controller for the pump.10an fuel supply ,10an return and twin 8an to the carb. Great system with no problems with 750HP@ 6500RPM

I have bought , built and used several different brands of fule pumps, regulators and filter in the last 25 yrs. I like your thinking of overkill, that is the way to go I now use Magnafuel and wish that I had bought the 500 pump to start with instead of cheaping out with the 275 pump because my motor only made 612 HP. I hopped it up later and ended up buying a 300 pump, I now have a motor that makes close to 900 HP and need anther pump Buy the big one now One other thing, call Magnafuel and follow thier instructions on which component, size and location, especially on the fuel filters and micron size ,to the letter for a trouble free system

I didn't know that they sold kits I bought a BG 280 pump first and then saw on here that they where not a street pump and saw a lot of Mopart members on here having troubles with BG pumps I ended up with the Magnafuel 275 pump with a BG 500 fuel filter (10 micron don't do that ) mounted between the tank and pump fed by a #10(5/8 inch) AN line and then #8(1/2 inch) return and # 8 main hard line to the BG four port regulator mounted in front of the motor on the elephant ears I ran a sixpak originally, hence the four port regulator. I really like both of my Mganfuel pumps I just wish that I had been bright enough to buy the Magnafuel 500 pump to start with, I even bought the bare pumps with no filters on them to save money

I run a pair of Holley black 150s in parallel with a pair of #10 lines from the tank to a pair of screen type filters into the pumps, a #10 line forward to a Mallory 4 port return style regulator and a #8 return line... this is for E-85... pressure holds steady at 7.5# with 130 needle and seats front and rear
