Helpful Comparison Insights

When you’re looking for the best fuel pumps for Holley 750 carbs, you’ll notice some key differences that can heavily influence your decision.

First off, consider in-tank vs. external pumps. The Holley 19350 and Aeromotive 11104 are both fantastic in-tank options. They shine when it comes to quieter operation, cooler fuel delivery (which prevents vapor lock and cavitation), and a cleaner look under the hood. However, they demand a more involved installation, often requiring you to drop your fuel tank and run a return line, which adds complexity and cost. On the other hand, external pumps like the Holley 12-801-1, Carter P4070, Edelbrock 1792, Holley Mighty Mite, and Mallory 4070M are generally easier to install. You can mount them almost anywhere along the fuel line, but they can sometimes be a bit noisier and more susceptible to heat.

Pressure and flow rate are absolutely critical for your Holley 750. A Holley 750 generally prefers around 6-7 PSI. Pumps like the Holley 12-801-1 (7 PSI), Carter P4070 (6-8 PSI), and Edelbrock 1792 (preset 6 PSI) are well-suited for street performance and moderately modified engines. They provide enough pressure and flow (around 70-100 GPH) to keep your carb happy without overwhelming it. For high-horsepower applications, especially those approaching 500+ HP or forced induction, you’ll need the much higher flow rates offered by the Holley 19350 and Aeromotive 11104 (both 340 LPH, which is roughly 90 GPH but designed for much higher pressure and continuous flow). The Mallory 4070M offers a good middle-ground with 140 GPH and adjustable pressure. The Holley Mighty Mite is strictly for low-demand, stock, or very specific setups due to its low 2-4 PSI and 32 GPH.

E85 compatibility is another important factor if you’re planning to run ethanol-blended fuels. The Holley 19350, Aeromotive 11104, and Mallory 4070M explicitly state E85 compatibility, meaning their internal components are designed to withstand the corrosive nature of ethanol. If you’re running E85, always choose a pump that’s rated for it to avoid premature pump failure.

Finally, think about cost and value. The Carter P4070 and Holley Mighty Mite offer budget-friendly entry points, but with compromises in flow or features. The Holley 12-801-1 and Edelbrock 1792 represent solid mid-range options that deliver excellent performance for most street applications. The high-flow in-tank pumps like the Holley 19350 and Aeromotive 11104 are a larger investment, but they provide superior performance and future-proofing, especially for high-horsepower builds.

Final Verdict

Choosing the right fuel pump for your Holley 750 carb really boils down to your specific needs and what kind of power you’re making.

If you’re after a reliable, no-frills external pump for a street-driven car with mild modifications, you can’t go wrong with the Holley 12-801-1 Red pump or the Carter P4070. Both are proven performers that offer consistent fuel delivery without breaking the bank. The Edelbrock 1792 is also an excellent choice if quiet operation is a top priority, offering that ideal 6 PSI for many Holley setups right out of the box.

For those running higher horsepower engines, considering E85, or simply wanting the best possible fuel delivery and quietest operation, the in-tank options like the Holley Fuel Pump Module Return 19350 or the Aeromotive 11104 Stealth 340 are absolutely worth the extra investment and installation effort. They provide incredible flow and stability, ensuring your Holley 750 is always fed, no matter how hard you push it. These are also smart choices if you’re thinking about future EFI upgrades.

And if you need a pump that offers a versatile balance of flow and adjustable pressure, along with E85 compatibility, the Mallory 4070M Series stands out as a strong performer for many street/strip applications.

Ultimately, invest in a fuel pump that matches your engine’s demands. Your Holley 750 carb will thank you for it with crisp throttle response and consistent power delivery!

FAQ Section

Q1: What PSI do I need for a Holley 750 carburetor?
A: Most Holley 750 carburetors operate optimally with a fuel pressure between 5.5 to 7 PSI. Going much higher than 7 PSI can overwhelm the needle and seat, potentially leading to flooding or inconsistent fuel levels in the float bowls.

Q2: Do I need a fuel pressure regulator with a Holley 750?
A: Yes, it’s highly recommended, and often necessary, especially with electric fuel pumps. Many aftermarket electric fuel pumps (like the Holley 12-801-1 Red pump, which delivers 7 PSI) can exceed the ideal pressure for a Holley 750 carburetor or can fluctuate. A good quality fuel pressure regulator ensures a consistent and controlled pressure to your Holley 750, preventing issues like flooding or fuel starvation and helping optimize performance.

Q3: Can I use an in-tank fuel pump with a Holley 750?
A: Absolutely! In-tank fuel pumps, like the Holley 19350 or Aeromotive 11104, are excellent choices for Holley 750 carbs, especially in high-performance applications. They offer advantages like quieter operation, cooler fuel delivery (reducing vapor lock), and consistent pressure. However, they usually require a return line to the fuel tank and a proper fuel pressure regulator specifically designed for return systems.

Q4: What’s the difference between GPH and LPH for fuel pumps?
A: GPH stands for Gallons Per Hour, and LPH stands for Liters Per Hour. Both are measurements of a fuel pump’s flow rate. To convert between them, remember that 1 gallon is approximately 3.785 liters. So, a pump rated at 100 GPH flows about 378.5 LPH. When selecting fuel pumps for Holley 750 carbs, ensure the flow rate is adequate for your engine’s maximum horsepower demands.

Q5: Is an electric fuel pump better than a mechanical one for a Holley 750?
A: For performance applications with a Holley 750 carburetor, electric fuel pumps often offer advantages over mechanical pumps. Electric pumps provide more consistent pressure, are less prone to heat soak (especially when mounted away from the engine), and can be mounted closer to the fuel tank for better priming. They can also deliver higher flow rates needed for modified engines. Mechanical pumps are simple and reliable for stock or mild applications but might struggle to keep up with a high-performance Holley 750 under heavy load.

Q6: Are these fuel pumps compatible with E85 for Holley 750 carbs?
A: Not all fuel pumps are E85 compatible, but some of the higher-performance options reviewed, such as the Holley 19350, Aeromotive 11104, and Mallory 4070M, are explicitly designed to handle E85 fuel. If you plan to run E85 with your Holley 750, it is crucial to select a fuel pump that is specifically rated for E85 to prevent premature pump failure due to ethanol’s corrosive properties. Also, remember to ensure your entire fuel system (lines, regulator, carburetor components) is E85 compatible.

Q7: How do I know if my fuel pump is failing when using a Holley 750?
A: Common signs of a failing fuel pump when running a Holley 750 carburetor include engine sputtering or misfiring under acceleration (especially at higher RPMs), poor engine performance, difficulty starting (especially when warm), loss of power, or the engine stalling out entirely. You might also notice a decrease in fuel pressure when measured with a gauge. Inconsistent fuel delivery directly impacts the performance of your Holley 750.
