Review AEROMOTIVE Fuel Tank Ford 3.3l Cyl Carb Naturally Aspirated Gas fits MUSTANG 1969–1970
The **Aeromotive VR71F3 Fuel Tank** is a meticulously engineered, high-performance replacement fuel tank specifically designed for the classic 1969-1970 Ford Mustang with a 3.3L inline-six engine featuring a carbureted, naturally aspirated fuel system. Crafted from premium-grade aluminum, this tank is built to deliver superior durability, corrosion resistance, and structural integrity, ensuring it can withstand the demands of both daily driving and spirited performance applications. Unlike stock units, which are often prone to leaks, warping, or inadequate fuel capacity, the Aeromotive VR71F3 is precision-machined to exacting specifications, featuring a seamless, smooth interior that minimizes fuel sloshing and maximizes efficiency. Its robust construction includes reinforced seams and a sturdy mounting bracket system, allowing for a secure and vibration-free installation that preserves the integrity of the fuel line connections and prevents premature wear on critical components.
One of the standout features of this tank is its **increased fuel capacity**, providing a noticeable boost in range and performance compared to the original equipment unit. The Aeromotive VR71F3 is equipped with a **high-flow fuel pickup**, ensuring a consistent and reliable fuel supply to the carburetor, even under heavy throttle demands or during aggressive driving conditions. This design eliminates the risk of fuel starvation, which can lead to stalling, hesitation, or poor acceleration common issues in older Mustangs with aging fuel systems. The tank s **integrated venting system** is also thoughtfully engineered to maintain optimal fuel pressure and prevent vapor lock, particularly in high-temperature environments, further enhancing reliability and performance.
For enthusiasts seeking a seamless upgrade, the Aeromotive VR71F3 is engineered to fit perfectly within the Mustang s engine bay, requiring minimal modifications to existing fuel line routing or mounting hardware. The tank s **clean, modern aesthetic** complements the classic lines of the 69-70 Mustang while offering a practical solution for those looking to extend their vehicle s lifespan or prepare it for high-performance modifications. Whether you're restoring a project car to showroom condition or fine-tuning a daily driver for better fuel economy and power delivery, this tank represents a premium investment in both performance and longevity. Backed by Aeromotive s reputation for quality and precision, the VR71F3 is the ideal choice for Mustang owners who demand nothing less than excellence in their fuel system components.
The Aeromotive VR71F3 fuel tank is a popular aftermarket upgrade for 69-70 Ford Mustangs with a 3.3L carbureted, naturally aspirated engine. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
---
### **Pros of the Aeromotive VR71F3 Fuel Tank**
1. **Increased Fuel Capacity** The stock fuel tank on a 69-70 Mustang holds around 12 gallons, but the VR71F3 expands capacity to approximately 18 gallons. This provides a significant range boost, reducing the frequency of refueling, which is especially useful for long-distance driving or track use.
2. **Improved Fuel Flow and Pressure** The VR71F3 features a high-flow fuel pump and a more efficient fuel line system, which helps maintain consistent fuel delivery to the carburetor. This can reduce fuel starvation issues, particularly during hard acceleration or high-performance driving.
3. **Durability and Quality Construction** Aeromotive is known for producing high-quality aluminum tanks that are resistant to corrosion and leaks. The VR71F3 is designed to handle the stresses of performance driving better than the stock plastic tank.
4. **Compatibility with Performance Modifications** If you plan to add performance upgrades like a hotter camshaft, forced induction, or a larger carburetor, the VR71F3 provides the extra fuel capacity needed to support these modifications without running out of gas.
5. **Easier Installation** While installation requires some mechanical skill, Aeromotive provides detailed instructions, and the tank is designed to fit within the Mustang s frame without major modifications to the chassis or fuel lines.
6. **Reduced Fuel Vaporization** The VR71F3 s design minimizes fuel vaporization, which can help prevent fuel line clogs and ensure a smoother power delivery, especially in hot climates.
7. **Aesthetic Appeal** The sleek aluminum construction looks more premium than the stock plastic tank, which may appeal to those who prioritize both function and appearance.

### **Cons of the Aeromotive VR71F3 Fuel Tank**
1. **Cost** The VR71F3 is significantly more expensive than the stock fuel tank, typically ranging between $300 and $500 depending on the retailer and any additional components needed (such as a new fuel pump or lines). This is a substantial investment for what is essentially a functional upgrade rather than a performance-enhancing one.
2. **Weight Increase** The VR71F3 is heavier than the stock tank due to its aluminum construction. While the weight difference is modest, it may slightly affect the Mustang s handling dynamics, particularly in lighter, sportier applications.
3. **Installation Complexity** Installing the VR71F3 requires removing the stock tank, rerouting fuel lines, and possibly adjusting the fuel sender unit and fuel gauge. This is not a simple weekend project and may require professional assistance, adding to the overall cost.
4. **Potential for Leaks or Improper Sealing** If not installed correctly, the VR71F3 could develop leaks at the fuel line connections or the tank itself. Proper sealing with high-quality gaskets and clamps is critical to avoid fuel spills or vapor leaks.
5. **Limited Benefit for Stock or Mildly Modified Engines** If your Mustang is running stock or with only minor carburetor tweaks, the extra fuel capacity may not be immediately noticeable. The real benefits (longer range, reduced fuel starvation) become more apparent with performance modifications or heavy driving.
6. **Compatibility with Some Fuel Systems** While the VR71F3 is designed for carbureted applications, some older or modified fuel systems (such as those with aftermarket fuel pumps or electronic fuel injection conversions) may require additional adjustments to ensure proper function.
7. **Space Constraints in the Mustang s Bay** The VR71F3 is slightly larger than the stock tank, which means it may rub against other components (such as the exhaust or suspension) in some Mustangs. Careful routing and potential modifications (like extending the fuel lines) may be necessary to avoid interference.
---
### **Conclusion**
The Aeromotive VR71F3 fuel tank is a worthwhile upgrade for 69-70 Mustang owners who prioritize fuel capacity, durability, and long-term reliability especially if they plan to push their engine with performance modifications. The increased range and improved fuel flow can make a noticeable difference in driving comfort and confidence, particularly for track use or long trips. However, the cost, installation complexity, and modest weight increase must be weighed against the benefits.
For owners who primarily drive their Mustangs casually or have no immediate plans for aggressive modifications, the stock tank may suffice, and the extra expense of the VR71F3 could be unnecessary. On the other hand, if you value fuel security, a premium build, and the potential for future upgrades, the VR71F3 is a solid investment.
---
### **Recommendation**
**Buy the Aeromotive VR71F3 if:**- You frequently drive long distances or use your Mustang for track days where fuel range is a concern.
- You plan to add performance modifications (such as a hotter carburetor, forced induction, or a performance cam) that will increase fuel demand.
- You want a durable, corrosion-resistant tank that will last longer than the stock plastic unit.
- You are comfortable with a moderately complex installation or are willing to pay for professional help.
**Skip the VR71F3 if:**- Your Mustang is stock or lightly modified, and you don t need the extra fuel capacity.
- You are on a tight budget and can find alternative ways to extend range (such as carrying extra fuel in a secondary tank).
- You prefer to avoid any modifications that could complicate future repairs or maintenance.
- You are not confident in your ability to install the tank correctly without professional assistance.
Ultimately, the VR71F3 is a practical choice for those who want to future-proof their Mustang s fuel system, but it is not a necessity for every owner. Carefully consider your driving habits and long-term goals before making the decision.
