So now we move into the higher end fuel systems for a Boosted Holley Carb engine. For this system you need to either modify your tank to allow installation of the in-tank fuel pump(s) or but a fuel tank already fabricated by the Tank Manufacturer.

There are two Major Players in the aftermarket [(internal fuel pump(s)] Fuel Tank market. AEROMOTIVE and Tanks Inc.

AEROMOTIVE does a lot of higher horsepower systems whereas Tanks Inc does more of the Enthusiast/road vehicle (fuel system upgrade)
type tanks. Either one makes nice products or you could build (or have fabricated) your own custom system.

So today I will use the AEROMOTIVE parts only because they have some nice schematics on the web.

So here are the schematics:

In the first schematic "Dual Phantom Redundant (single Holley Carb) it states that the system can support 850 horsepower and if one fuel pump were to die on you the system has a second fuel pump installed in the tank like the first one that could allow you to continue on down the road with your 850 HP Boosted Engine vehicle. 850 HP on a true Street Car is a bunch of horsepower. We had a 780 HP "Mule" Boosted EFI vehicle at work and many engineers were not capable of driving it on the street and shifting the manual trans at the same time. Auto trans might be a different story.

In the second schematic "Dual Phantom STAGED (single Holley Carb) it states that the system can support 1700 horsepower and if one fuel pump gets you down the road on the street the system has a second fuel pump installed in the tank like the first one that could allow you to drag race the vehicle with your 1700 HP Boosted Engine fuel system capability. You will not make 1700 hp blowing thru a single 850 cfm Holley Carb in most cases. I know of one case where a 505 chebby was close to that number with a large Dominator carb installed.

All that being said, there are fuel systems out there today that can handle very high HP engines.

The Tanks, inc and Aeromotive tank I believe are made by the same supplier so most of the work could be performed on either basic tank.
