When it comes to powering a 1000hp engine, the fuel pump setup is a crucial consideration. Various factors, such as fuel hose diameter, system electrical voltage, and amperage capabilities, influence the flow capability for horsepower support. While there are differing opinions on the ideal fuel pump configuration, ensuring adequate fuel supply for 100 hp typically requires 10 actual gallons per hour (gph) at working pressure. This means that for a 1000 hp engine, a fuel pump with a flow rate of at least 100 gph is necessary. To achieve this, high-performance fuel pumps, such as the AEM 50-1000 340 LPH High Flow In-Tank Fuel Pump, are designed to deliver reliable performance and a high volume of fuel flow. Additionally, the A1000 In-Line Fuel Pump by Aeromotive is another option that supports up to 1000 HP in naturally aspirated engines.

The pump features a compact 39mm diameter that fits most applications and an offset inlet design that simplifies installation. It is constructed from black-plated steel with laser etching and includes a wiring harness, pre-filter, end cap, and rubber buffer sleeve. The pump also comes with a universal pre-filter, although this may not fit all vehicles.
The AEM 50-1000 is designed for in-tank mounting and is compatible with gasoline vehicles, although pump life may be reduced when used with E85 fuel. It has a minimum voltage input of 6 volts and a maximum of 18 volts, and its flow capability for horsepower support depends on the fuel hose diameter and the system's electrical voltage and amperage capabilities.
The pump weighs 12.5oz (354 grams) and has an outside diameter of 39mm. The inlet fitting measures 7.7mm ID and 11.0mm OD, while the offset inline outlet fitting is designed for an 8mm hose clamp. The impeller uses a single scroll ceramic turbine design. The connector terminal is a 6mm spade with positive and negative connections. The fuse is rated for 20 amps at 13.5 volts, and the power rating is given as 43 PSI at 13.5 volts at the pump terminal with a BSFC of 0.5.
It is important to note that the electrical plug's polarity in your tank must be correct for this pump, and AEM does not recommend modifying the tank to accommodate the pump. The Vehicle Search function on the AEM website can be used to check compatibility with your vehicle.

Calculations for fuel pump setup
When setting up a fuel pump, there are several calculations that need to be considered to ensure optimal performance. Firstly, it is crucial to determine the desired horsepower, fuel pressure, and fuel type. These factors directly influence the fuel pump flow rate required to meet your specific needs.
For instance, let's consider a scenario where you are aiming for 1000 horsepower. The fuel pump's flow capability to support this horsepower depends on factors such as the fuel hose diameter and the electrical system's voltage and amperage capabilities. In this case, a fuel pump with a capacity of around 125 gallons per hour (GPH) at 45 pounds per square inch (PSI) would be suitable, with a maximum pressure of 125 PSI.
Another example of a fuel pump capable of supporting 1000 horsepower is the AEM 50-1000 AEM 340 LPH High Flow In-Tank Fuel Pump. This particular pump delivers a flow rate of 340 liters per hour (LPH) or 84 gallons per hour (GPH) at 40 PSI and can support over 1000 horsepower at 43 PSI.
It is important to note that the fuel pump sizing for your vehicle should be carefully considered before purchasing. Online tools such as vehicle search functions and fuel pump calculators can aid in determining the appropriate fuel pump setup. These tools take into account factors such as induction type (naturally aspirated, turbocharged, or supercharged), fuel type (gasoline, ethanol, methanol, etc.), and fuel pressure to provide an estimated flow rate required for your desired horsepower.
Additionally, it is recommended to refer to a tuner or engine builder for expert advice on the recommended fuel pump and injector size, as calculations and estimations may vary based on specific vehicle and performance requirements.

Fuel pump sizing
For engines with 1000 hp, the fuel pump's flow rate and pressure capabilities become critical. A general rule of thumb is that a naturally aspirated engine with 1000 hp requires approximately 90 gallons per hour (gph) of fuel flow, while a forced induction or turbocharged engine with the same horsepower may demand up to 125 gph or more. These values can vary depending on factors such as fuel type and ethanol content.
To ensure sufficient fuel delivery, it is recommended to choose a fuel pump that exceeds the minimum required flow rate. For example, the AEM 50-1000 AEM 340 LPH High Flow In-Tank Fuel Pump is designed to support over 1000 hp. It delivers a flow rate of 340 litres per hour (lph) or 84 gallons per hour (gph) at 40 pounds per square inch (PSI) and can support over 1000 hp at 43 PSI. This pump is designed for gasoline-powered vehicles and features a compact design that fits most applications.
Another important consideration is the electrical compatibility of the fuel pump with the vehicle's system. AEM's High Flow Fuel Pumps, for instance, require careful assessment of the vehicle's factory fuel pump wiring to ensure it can handle the current draw of the high-flow pumps. Additionally, voltage and amp draw play a significant role in pump performance, with higher voltages typically resulting in increased flow rates.
When sizing a fuel pump for 1000 hp, it is advisable to consult fuel pump calculators and seek recommendations specific to your vehicle. For instance, the A1000 In-Line Fuel Pump by Aeromotive is designed to support up to 1000 hp in naturally aspirated engines and up to 1300 hp in fuel-injected engines. It is crucial to verify the compatibility of the fuel pump with the specific engine configuration and fuel type, as some pumps are not suitable for diesel fuel or emission-controlled vehicles.

Frequently asked questions
The A1000 In-Line Fuel Pump by Aeromotive is a durable and reliable option that supports up to 1000 HP for naturally aspirated fuel-injected engines. Another option is the 91901 1000HP In-Tank Power Module Fuel Pump by FUELAB, which is rated up to 1000HP and is compatible with gasoline, diesel, methanol, and ethanol.
According to Summit Racing, the formula to calculate the optimal GPH is: Optimal GPH = (Max. HP x BSFC) / 6. For example, if your engine has a maximum HP of 200 and a BSFC of 0.50, the calculation would be: Optimal GPH = (200 HP x 0.50) / 6 = 16.67 GPH.
It is recommended to oversize the fuel pump system to ensure sufficient fuel delivery. Nitrous engines, turbochargers, and superchargers require more fuel and pressure. The AEM400 fuel pump is a good option for elevated fuel pressures and outperforms 525lph pumps at 70psi or higher.
It is important to use high-quality components that can handle the required fuel flow and pressure. The fuel lines should be at least 3/8 inches in diameter to minimize flow restrictions. A return-style fuel system can be considered for better fuel delivery and pressure regulation. Additionally, a flex fuel sensor can be used to account for ethanol content variations.
