For performance enthusiasts pushing the limits of their Ford Explorer ST, the fuel system is one of the biggest bottlenecks. The stock high-pressure fuel pump (HPFP) and injectors simply aren’t designed to support the kind of power levels that modified Explorer STs can achieve—especially on E85. That’s where the Goliath High-Pressure Fuel Pump from Nostrum High Performance steps in, offering an unparalleled 60% increase in fuel flow over stock and unlocking 750+ wheel horsepower (whp) potential.
If you’re looking to make serious power, reduce fuel starvation, and future-proof your build, this article will walk you through the capabilities, features, and benefits of the Goliath HPFP—and why it’s the ultimate fuel system upgrade for your Explorer ST.
Why You Need a High-Performance Fuel System
The 3.0L EcoBoost engine in the Explorer ST is a powerhouse, but stock fuel system limitations start to show when you increase boost, upgrade turbos, or switch to ethanol-based fuels like E85. Here’s why a high-performance fuel system is crucial for making big power:
✅ Stock fuel pumps max out around 500-550whp, creating a barrier for further tuning.
✅ E85 requires 30-40% more fuel than gasoline due to its lower energy density.
✅ Fuel starvation leads to lean conditions, increasing the risk of knock and engine failure.
✅ Bigger turbos, aggressive tunes, and high-boost setups need more fuel flow to sustain safe and reliable power.
The Goliath HPFP solves all of these problems by providing the highest fuel flow of any pump available for the 3.0L EcoBoost platform.
Key Features of the Goliath High-Pressure Fuel Pump
The Nostrum Goliath HPFP isn’t just an upgrade—it’s a complete fuel system solution designed for reliability and extreme performance.
🔹 60% Flow Rate Increase Over Stock
With a massive 60% increase in fuel flow, the Goliath HPFP allows the Explorer ST to safely run higher boost levels, upgraded turbos, and full E85 fuel. No other HPFP on the market offers this level of fuel capacity.
🔹 Custom Formed Stainless-Steel Hard Line
Fuel line routing is crucial for OEM-like fitment and reliability. Nostrum provides a custom-formed stainless steel hard line for a seamless installation without the need for modifications.
🔹 Fully Stainless-Welded Construction
Unlike some aftermarket pumps, the Goliath HPFP is fully welded with stainless steel, eliminating the risk of fuel leaks and ensuring long-term durability.
🔹 OEM SAE Quick-Connect Fitting
The low-evap quick-connect fitting maintains OEM fuel system integrity, preventing vapor leaks and ensuring proper emissions compliance.
Stage 3 Injectors: The Perfect Pairing for Maximum Performance
A high-flow fuel pump is only one piece of the puzzle. To fully utilize the increased fuel supply, you need bigger injectors. That’s why Nostrum offers their Stage 3 Direct Injectors, which provide a 96% increase in flow over stock—the largest GDI injector available for the Explorer ST.
🔹 96% More Flow → Delivers massive amounts of fuel for high-horsepower builds.
🔹 OEM-Equivalent Spray Pattern → Maintains smooth drivability, prevents cold start issues, and ensures proper combustion.
🔹 Direct Replacement → Installs just like stock injectors with no modifications needed.
Performance Potential: How Much Power Can You Make?
So, what kind of horsepower can you achieve with the Goliath HPFP + Stage 3 Injectors?
| Fuel Type | Estimated HP Potential |
|---|---|
| 93 Octane | 650-700+ whp |
| E85 | 750+ whp |
🚀 With the right turbos and tuning, the Explorer ST can reach supercar-level horsepower!

Installation & Tuning Considerations
🔹 Professional Installation Recommended
Although the Goliath HPFP is a direct-fit upgrade, installation requires specialized tools and knowledge of high-pressure fuel systems. If you’re not experienced with direct injection (DI) fuel systems, have a professional shop handle the install.
🔹 Tuning is Required
Because of the higher fuel flow rates, the ECU must be tuned to account for the increased fuel supply. Without tuning, the vehicle won’t run correctly and could suffer from fuel trims that are too rich or lean.
🔹 Ethanol Fueling Considerations
-
Full E85 is recommended for maximum power.
-
Avoid intermediate ethanol blends (E30-E50)—they can cause fuel additives to separate, leading to clogged injectors.
-
If using intermediate blends, run 93 octane occasionally to clear out any buildup.
Frequently Asked Questions (FAQs)
Q: Why does Nostrum emphasize OEM-equivalent spray patterns?
A bad spray pattern can cause poor drivability, fuel dilution, and even engine wear. Nostrum’s injectors are engineered to match OEM spray characteristics, ensuring:
✔ Smooth cold starts
✔ Stable idling and low-speed drivability
✔ No excessive soot or fuel dilution
Q: Why does E85 make less power than 93 octane in some cases?
E85 has less energy per gallon than gasoline, so while it allows for more aggressive timing and boost, it requires more fuel flow to make the same power. With a fully optimized build, E85 still provides the highest horsepower ceiling.
Q: Can I run straight ethanol with this pump?
✅ Yes! The Goliath HPFP is fully compatible with pump E85.
🚫 Avoid E30-E50 blends, as they can cause fuel additives to separate and clog the fuel system.
