Review CJ CLASSIC TRUCKS Fuel Tank Conversion Kit Truck Frame Rail Mount Chevy/gmc fits 1967–1972

The **CJ Classic FTK9 Fuel Tank Conversion Kit with Frame Rail Mount** is a meticulously engineered solution designed to transform the fuel system of classic Chevy and GMC trucks from the iconic 1967 through 1972 model years, offering a seamless blend of modern reliability and vintage authenticity. This high-performance conversion kit replaces the original, often problematic fuel tank with a robust, corrosion-resistant **FTK9 aluminum fuel tank**, engineered to deliver superior durability while maintaining an unmistakably classic aesthetic. The tank s sleek, polished finish not only enhances the truck s visual appeal but also ensures longevity, as aluminum resists rust and deterioration far better than traditional steel tanks, a common weakness in older vehicles. The FTK9 is strategically positioned to maximize fuel capacity while accommodating the unique underbody constraints of these legendary trucks, ensuring a snug fit without compromising functionality.

What truly sets this kit apart is its **frame rail mounting system**, a precision-engineered solution that securely fastens the fuel tank to the truck s structural frame rails, eliminating the need for fragile or poorly positioned brackets that can lead to leaks or shifting over time. The mounting hardware is crafted from heavy-duty steel, designed to withstand the rigors of off-road adventures and daily driving alike, while the tank s integrated **quick-disconnect fuel line fittings** simplify maintenance and refueling operations. These fittings are engineered for a secure, leak-proof connection, reducing the risk of spills and ensuring a clean, professional installation that any detail-oriented enthusiast would be proud of.

Beyond its practical benefits, the CJ Classic FTK9 conversion kit is a testament to thoughtful engineering tailored specifically for the needs of classic truck owners. The kit includes all necessary components from the tank itself to mounting brackets, fuel lines, and clamps along with detailed, step-by-step installation instructions that guide users through the process with clarity. Whether you re restoring a show-worthy C10 or upgrading a daily driver, this conversion kit not only addresses the reliability concerns of aging fuel systems but also preserves the iconic character of your truck. With its combination of modern performance enhancements and timeless design, the FTK9 is more than just an upgrade it s a statement of craftsmanship and attention to detail, ensuring your Chevy or GMC remains as legendary in the road ahead as it was on the day it rolled off the assembly line.

The **CJ Classic FTK9 Fuel Tank Conversion Kit with Frame Rail Mount** is designed for 1967 1972 Chevy/GMC trucks, particularly those with the classic C10/C20/C30/C40/C50/C60/C70/C80 bodies. This kit replaces the stock fuel tank with a larger, more durable aftermarket unit and includes frame rail mounting hardware. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

1. **Increased Fuel Capacity**

The FTK9 kit typically offers a larger fuel tank than the stock unit, providing more range between refills. This is especially beneficial for long-distance driving, towing, or off-road use where fuel efficiency may be compromised.

2. **Improved Durability and Safety**

Aftermarket fuel tanks are often constructed from heavier-gauge steel or aluminum, making them less prone to corrosion, leaks, or damage from impacts. The frame rail mounting ensures a secure installation, reducing the risk of shifting or detachment during rough driving.

3. **Compatibility with Modern Fuel Systems**

Many aftermarket fuel tanks include features like improved fuel line routing, better sealing, and compatibility with modern fuel pumps or injectors. This can help prevent vapor lock or fuel starvation issues that older trucks may experience.

4. **Easier Maintenance and Accessibility**

The FTK9 kit is designed for straightforward installation, often requiring minimal modifications to the truck s frame or body. The frame rail mount eliminates the need for welding or extensive fabrication, making it a DIY-friendly upgrade.

5. **Aesthetic and Functional Upgrades**

Some kits include polished or customizable fuel tanks that enhance the truck s appearance while maintaining functionality. The frame rail mount also provides a cleaner look by hiding the tank securely beneath the truck.

6. **Reduced Risk of Fuel Leaks**

Stock fuel tanks on older trucks are notorious for developing leaks due to age, rust, or improper sealing. A new, properly installed aftermarket tank significantly reduces this risk, especially in trucks used for heavy-duty or off-road applications.

7. **Support for Performance Modifications**

If you plan to modify your truck with a turbocharger, supercharger, or other performance upgrades, a larger fuel tank can help accommodate increased fuel demand without running out of gas mid-journey.

---

### **Cons**

1. **Cost**

The FTK9 kit is not a cheap upgrade. Depending on the brand and additional accessories (fuel lines, gauges, or mounting hardware), the total cost can range from **$300 to $800 or more**. This is a significant investment for a single component, though it may be justified for trucks used heavily or for long-term reliability.

2. **Installation Complexity**

While the kit is designed for ease of installation, it still requires some mechanical skill. You ll need to:

- Remove the stock fuel tank and related components (lines, sender unit, etc.).

- Install the new tank, ensuring proper fuel line routing and sealing.

- Mount the tank securely to the frame rails, which may involve adjusting or modifying existing hardware.

If you re not comfortable with basic automotive work, you may need to pay a mechanic for installation, adding to the cost.

3. **Potential for Improper Fitment**

Not all 1967 1972 Chevy/GMC trucks are identical, and frame rail configurations can vary slightly between models (e.g., C10 vs. C20 vs. C30). While the FTK9 kit is designed to fit a wide range of trucks, there s a chance you may encounter fitment issues with your specific build, requiring additional modifications or adjustments.

4. **Weight Considerations**

A larger fuel tank adds weight to the truck, which can slightly reduce fuel economy and handling responsiveness. However, this is usually negligible unless you re running an extremely heavy load or high-performance engine.

5. **Fuel Line Routing Challenges**

Depending on your truck s body style or modifications, routing fuel lines from the new tank to the engine or fuel pump may require creative solutions. This could involve cutting or relocating existing lines, which adds complexity to the installation.

6. **Potential for Aftermarket Parts Compatibility Issues**

If your truck has non-standard fuel system components (e.g., an aftermarket fuel pump, custom fuel lines, or a modified sender unit), you may need to source additional parts to ensure compatibility with the FTK9 kit. This could increase the overall cost and time required for the upgrade.

7. **Limited Customization Options**

While some kits offer slight variations in tank size or finish, the FTK9 is a standardized product. If you re looking for a highly customized or unique fuel tank design, you may need to explore other options or work with a fabricator.

---

### **Conclusion**

The **CJ Classic FTK9 Fuel Tank Conversion Kit with Frame Rail Mount** is a solid choice for owners of 1967 1972 Chevy/GMC trucks who want to improve fuel capacity, durability, and reliability without undertaking a major fabrication project. The benefits such as increased fuel range, reduced leak risks, and easier installation outweigh the drawbacks for most users, especially those who prioritize long-term functionality and off-road or heavy-duty use.

However, the kit is not without its challenges. The upfront cost, potential fitment issues, and the need for some mechanical skill to install it properly are factors to consider. If you re comfortable with basic automotive work and your truck falls within the supported range, the FTK9 is a worthwhile investment. For those on a tight budget or with limited DIY experience, the cost and complexity may be prohibitive, and alternative solutions (such as a smaller aftermarket tank or a stock replacement) might be more practical.

---

### **Recommendation**

**Buy the CJ Classic FTK9 Kit if:**

- You own a 1967 1972 Chevy/GMC truck (C10/C20/C30/C40/C50/C60/C70/C80) and want to replace your stock fuel tank.

- You prioritize increased fuel capacity, durability, and a secure installation over cost savings.

- You re willing to invest the time and effort into installation, either yourself or with the help of a mechanic.

- Your truck is used for heavy-duty, towing, or off-road use where fuel range and reliability are critical.

- You want a relatively straightforward upgrade that doesn t require extensive fabrication.

**Avoid the FTK9 Kit if:**

- You re on a tight budget and cannot justify the cost of a new fuel tank.

- Your truck has highly modified or non-standard fuel system components that may not be compatible with the kit.

- You lack basic mechanical skills or tools and are unwilling to pay for professional installation.

- You re only planning light-duty use and don t need the increased fuel capacity.

- You prefer a more customized or minimalist fuel tank solution.

**Alternatives to Consider:**

- **Smaller Aftermarket Tank:** If you don t need the maximum capacity, a less expensive aftermarket tank (e.g., from **CJ Classic, Fuel-Tech, or local fabricators**) may suffice.

- **Stock Replacement:** If your stock tank is still functional but leaking, replacing it with a new OEM-style tank (from a junkyard or parts supplier) could be cheaper.

- **DIY Fabrication:** For a highly customized solution, you could fabricate your own tank from steel or aluminum, though this requires welding skills and more time.

- **Fuel Tank Extenders:** Some kits offer extenders or auxiliary tanks that can be added to your existing tank without a full replacement.

**Final Verdict:**

For most owners of 1967 1972 Chevy/GMC trucks seeking a reliable, high-capacity fuel tank upgrade, the **CJ Classic FTK9 Kit is a strong recommendation**. It strikes a balance between performance, durability, and ease of installation, making it one of the best aftermarket options available for this generation of trucks. Just be prepared for the cost and ensure your truck s fitment aligns with the kit s specifications.
