Electric fuel pump selection

[BILL-C]

I'm looking for a recommendation from people with real world experience for the best electric fuel pump for a 750 hp N/A carbed drag race application. The Holley blue pump isn't quite keeping up. I just installed a Holley black HP 125 pump and it's defective. Only making 3 psi. I need to be headed to race track in 4 days. No time for totally re engineering fuel system. pump needs to be dead head style like blue and black.

Black should be up to the task, everything else in the fuel system up to the task? (No hard 90’s, 5/16” hose, restrictive fuel filter)

A pair of Carter P4594 pumps in parallel will feed this engine reliabily with room to spare.
Dead head friendly. no regulator is needed.
Both the holley blue and black pumps are unreliable. They don't last long.

Not now nor have I ever been a fan of Holley fuel pumps...regulators work, pumps have issues....I've ran Magnafuel as well and had issues... Now if it's electric the only one I'll run is from Aeromotive....just my preference..

They do have a pump for just about any level of performance that you need and also engineered fuel systems....I'm not a fan of piece mailing fuel systems together with whatever.....I'm also not a fan of deadhead systems unless it's feeding nitrous......

Never buy another pump again........

Carter 4600, 100 gph pump. 750 hp needs 63 gph, so plenty of reserve.

Any electric pumps performance is very dependent on it being able to pull enough current thru the wire and whatever connectors are used to feed it!
What was able to power the blue pump might not cut it for bigger pumps!

I helped a buddy out with a issue like this once and he had his Son crimp on the connections to his terminal block.
The fix was that his Son used Red instead of yellow gauge connectors and to get the gauge wire into those red connectors he cut some strands of wire out.

The end result was the pump could not pull the current it needed thru what was now effectively one gauge smaller wire!
