Fuel pumps Big HP

Hi all just wondering what fuel pumps, filters,..pressure regulators etc etc people are using for higher horsepower engines... Are surge tanks necessary
photos would be great..

CIS or EFI?

I run an aeromotive A1000 with EFI.
That's on a 930 that has run 700+HP at the wheels on a dyno jet.
Great fuel pump with no issues.
It's able to keep consistent fuel pressure of 42 PSI under all conditions.

A1000 Fuel Pump - Aeromotive

+1 on A1000

Thanks for the reply do you run pre-filter before pump and what pressure regulator do you run.. this is for a EFI motor

[Menmojo]

I have the A1000 mounted on the floor of the front trunk next to the fuel cell.
I can't remember the brand of the regulator and I'm not using a surge tank.
I hope this helps......

I am running dual 044 Bosch motorsports pumps, and an Aeromotive FPR. Thats on a EFI 930. Rock steady 50 PSI

Brad will find out soon enough when he starts running e85 about the 044s and longevity

I've ran an Aeromotive on a different car and twin 044's. These are both plenty for big hp.

Running twin Bosch 044's and a Fuelabs FPR; EFI 544fwhp/514lbft as measured on an engine dyno.

ETA - stock 964 in-tank filter before the first pump, then stock 965 filter after second pump and before the injection rail

Here is my 2 on twin pumps Efi and big boost/ power. If and when you are boosting big and one pump fails you just went lean big time. If your single takes a crap you shut down. I know there are safeguards one can take in the programming but .....

That is a very good point. Better to have to call a flatbed than call Mahle.

Thanks for the input guys ...do these all fit in the standard location or does they have to be relocated... any need for a surge tank.. picks pics...

Porsche race cars always had at least two fuel pumps in parallel. They would run with only one fuel pump but they had 2 or 3 in parallel so if one failed during an endurance or sprint race the car could still finish.
