Fuel pump upgrade

Does anyone know of a fuel pump drop in upgrade for a supercharged 6.4, I have the a2speed now. The problem is it's limited to 700-750WHP, so what are you guys doing over 800 to the wheels? Help please.

I have not seen a single pump that will support over 750 so I'm gonna say dual pump at 725 and up to 1000 on pump 93 and 1200 on race fuel. which is pretty much what Fore recommends.

That's what I went with when switching to E85, get the upgraded lines so you don't have to worrry about fumes in the cabin.

Most of the stuff I’m see is for 15 and up hellcat, will it fit on my 2014 srt8? Is the factory connections the same?

In the same boat I got that Arrington fuel pump says it's good for 700whp just forged 392 and going to 12 to 14 psi on edelbrock sc 1000cc I injectors. But with stock lines most people only get to around 675 whp. Ya got to get that fore dual hat setup costs 2 grand. Iam just gonna roll the dice see what it does car at the tune shop now if it gets 675 or close to 700 with good pressure I mihjt just leave it alone
