7 is fine. any off the rack electric that can make 7-14 psi and pump 7 gph or more. dont forget a regulator so you can run a fuel bypass keeping your fuel cooler
just get a 225 or u could go to 255 but that over kill. 225 supports i think 500hp . stock is usually 190 which supports to 300. dont quote me on hp supports its been awhile. alot of people rock stock pumps( and they got alot done) until they get a turbo or supercharger thats when u gotta update fuel system pumps,injuectors etc. i got a 5.0 with full bolt ons chiped and cammed with a 190 pump and she does just fine.
idk... but psi for a carb with its own float.
I have a 318 mopar that's been upgraded to a 4 barrel holly carb my fuel pump doesn't work and when I took it out it stripped the block so I'm going to an electric fuel pump but I don't know how many gph I need... I just got the car a month ago as a project so I'm not sure how many hp it makes all I know is its a 69 barracuda fastback with 318 that's been upgraded to a holly intake 4barrel holly 600 carb and has headers .. The car was set up for drag racing it has upgraded clutch suspension wheels and it has a kill switch so the motor has most likely been bored out to a 340 can anyone help? Thanx
