Fuel delivery
Hey all,
For you big horse guys, what is your fuel delivery system like? GPH on the fuel pumps, manual or electric, regulated or not? This is going on a Holley carb btw (not the 4500 series).

Pretty intense little system there hahaha is that much necessary or is that just playing it safe?
Would mating up a say, 140gph free flow 14psi max Holley electric fuel pump make sense considering it is a Holley carb? More or less gph here for the 500+ hp?

Im still wondering what was meant by the 8 minute remark? He surely isnt insinuating that a 140 gph fuel pump is going to drain my tank every 8 minutes when Im driving...because...
