Fuel pump size requirements for 150 shot Foxbody
Selecting the right fuel pump for a 150-shot nitrous oxide (N2O) system in a Foxbody Mustang is critical to ensure both performance and safety. A 150-shot introduces a significant increase in fuel demand, as nitrous oxide requires additional fuel to burn efficiently. The stock fuel pump in a Foxbody is typically rated for around 30-40 psi and flows approximately 30-50 liters per hour (LPH), which is insufficient for the added load. Upgrading to a high-flow fuel pump is non-negotiable, but the exact size depends on factors like engine size, fuel pressure, and injector capacity.
To calculate the required fuel pump size, start by determining the total fuel demand during nitrous activation. A 150-shot system typically requires a 50% increase in fuel flow, meaning the pump must deliver at least 1.5 times the base fuel requirement. For a 5.0L V8 Foxbody, this translates to a pump capable of flowing 150-200 LPH at 43-58 psi. High-performance pumps like the Aeromotive A1000 or Walbro 450 are popular choices, as they can handle the increased demand while maintaining stable fuel pressure. Pairing the pump with a fuel pressure regulator and upgraded fuel lines ensures consistent delivery under high-stress conditions.
While larger pumps may seem better, oversizing can lead to inefficiencies and unnecessary strain on the electrical system. A pump that flows significantly more than required can cause excessive fuel pressure, leading to leaky injectors or fuel boiling in the rail. Conversely, undersizing results in fuel starvation, lean conditions, and potential engine damage. Aim for a pump that meets the calculated demand without exceeding it by more than 20%. For a 150-shot Foxbody, a 255 LPH pump is often ideal, striking a balance between performance and reliability.
Installation considerations are equally important. Ensure the fuel pump is compatible with the fuel type (e.g., E85 requires specific materials) and that the wiring can handle the increased amperage draw. A relay kit is recommended to protect the factory wiring harness. Additionally, an in-tank or external pump setup depends on the fuel cell design and space constraints. External pumps offer easier maintenance but require proper mounting and ventilation to prevent overheating.
In summary, a 150-shot Foxbody demands a fuel pump upgrade to meet the increased fuel requirements of nitrous oxide. A pump flowing 150-200 LPH at 43-58 psi, such as the Aeromotive A1000, is typically sufficient. Avoid oversizing to prevent inefficiencies, and ensure compatibility with fuel type and electrical system capacity. Proper installation, including a relay kit and upgraded fuel lines, guarantees reliable performance under extreme conditions. This approach ensures the engine receives adequate fuel for safe and efficient nitrous operation.

Upgrading fuel lines for 150 shot Foxbody setup
Upgrading fuel lines is a critical step when preparing a Foxbody for a 150 shot nitrous setup. The stock fuel system, designed for naturally aspirated performance, cannot handle the increased fuel demand under boost. A 150 shot introduces roughly 150 extra horsepower, requiring a fuel pump capable of delivering at least 255 liters per hour (LPH) at 43 PSI to maintain proper air-fuel ratios. However, the pump is only as effective as the lines feeding it. Stock fuel lines, typically 3/8-inch or smaller, restrict flow and create bottlenecks, leading to lean conditions and potential engine damage.
Begin by replacing the stock fuel lines with high-flow alternatives. Opt for 5/16-inch or 3/8-inch stainless steel or nylon-reinforced rubber lines, which offer increased diameter and durability. Stainless steel lines resist corrosion and heat, while nylon-reinforced rubber provides flexibility for easier installation. Ensure the lines are rated for ethanol-blended fuels, as nitrous setups often require higher octane fuels containing ethanol. Properly route the new lines away from heat sources like exhaust manifolds and headers to prevent fuel vaporization and pressure drops.
Next, address the fuel filter and fittings. Install a high-flow, inline fuel filter rated for at least 100 microns to prevent contaminants from reaching the injectors. Use AN fittings (e.g., -6 AN) for secure connections and compatibility with aftermarket fuel systems. Double-check all fittings for leaks using a soapy water solution, as even minor leaks can lead to fuel starvation under load. Consider adding a pre-pump filter if your setup includes a high-pressure fuel pump to extend its lifespan.
Finally, integrate a return-style fuel system if your Foxbody doesn’t already have one. A return line allows excess fuel to cycle back to the tank, maintaining consistent pressure and preventing regulator overload. This is especially important for nitrous setups, where precise fuel delivery is critical. Use a fuel pressure gauge to monitor pressure at idle, cruising, and full throttle, adjusting the regulator as needed to maintain 43–45 PSI under boost. Regularly inspect the lines for wear, abrasion, or leaks, particularly after hard launches or high-speed runs.
Upgrading fuel lines is not just about capacity—it’s about reliability and safety. A well-designed fuel system ensures your Foxbody delivers consistent power without risking engine failure. Pair these upgrades with a compatible fuel pump, such as a Walbro 255 or Aeromotive A1000, and a nitrous-specific tune for optimal results. Done correctly, your 150 shot setup will perform reliably, whether on the strip or the street.
