Next up in our fuel system management series is picking the correct regulator. Let’s start with our first fuel pump example: a 1,000-horsepower carbureted system running at 7 psi on 13.5 volts with 500 lbs/hr of fuel, and needing our A1000. There are mathematical equations that can help you determine line size needed, but for sake of ease, let’s reference our diagrams. For an A1000 carbureted system, you need AN-10 lines through the pump and to the regulator, two AN-06 lines from the regulator to the carburetor, and an AN-08 return line. We have multiple regulator options for this kind of situation. One option is our 13204 A1000 carbureted bypass regulator. Our second fuel pump example was as follows: a 1,200 flywheel horsepower EFI system running at 65 psi base + boost on 13.5 volts with 804 lbs/hr of fuel. This example requires our Eliminator pump. For an Eliminator EFI system, you need AN-12 lines into the pump, AN-10 lines after the pump, AN-08 lines through the rails and regulator, and an AN-08 return line to the tank. We have multiple regulator options for this kind of situation. One option is our 13134 Pro-Series Extreme Flow EFI regulator. Our third fuel pump example is as follows: a 1,000 flywheel horsepower EFI system running at 65 psi base + boost on 13.5 volts with 900 lbs/hr of fuel. This system needs our Pro Series pump, which flows up to 1,200 lbs/hr at 65 psi and 13.5 volts. One option is our 13305 Big EFI X1 regulator. We have other stylistic options for all of these set-ups.
