Review MOPAR Nos 1976-9 Fuel Tank Roll Over Valve Chrysler Plymouth Dodge fits CJ8

The **Mopar 4002012 NOS (New Old Stock) Fuel Tank Roll Valve** is a meticulously preserved, high-performance component designed specifically for classic Chrysler, Plymouth, and Dodge vehicles from the 1976 to 1979 model years, including the iconic CJ-8 Jeep. This roll valve, also known as a fuel shutoff valve, is a critical safety and operational feature that prevents fuel from spilling out of the tank when the vehicle is tilted or inverted, such as during off-road driving or rollovers. Crafted from durable, corrosion-resistant materials, this NOS part retains its original factory specifications, ensuring a perfect fit and reliable function without the need for modifications. The valve operates smoothly, allowing fuel to flow freely when the vehicle is upright while sealing tightly when tipped, thus maintaining fuel integrity and reducing the risk of leaks or spills. Ideal for enthusiasts restoring or maintaining their vintage vehicles, this roll valve is a must-have for those seeking authenticity and performance. Its pristine condition and direct compatibility with the 1976 1979 fuel tanks make it a seamless upgrade or replacement option, preserving the original character of the vehicle while ensuring optimal fuel system reliability. Whether used in a classic muscle car, a rugged off-roader, or a restored CJ-8, this NOS roll valve exemplifies the quality and precision of Mopar s aftermarket solutions, delivering both functionality and historical accuracy.

### **Pros and Cons of Buying a NOS (New Old Stock) Mopar 4002012 Fuel Tank Roll Valve (1976 199 Fuel Tank Compatible for Chrysler, Plymouth, Dodge CJ8)**

1. **Authentic Fit and Functionality** The NOS roll valve is a direct replacement part designed specifically for the 1976 199 fuel tanks used in Chrysler, Plymouth, and Dodge vehicles (including the CJ8). It ensures proper fuel flow and prevents spillage when the vehicle is tilted.

2. **High-Quality Construction** Mopar NOS parts are known for their durability and reliability, often made from the same materials and standards as original equipment. This reduces the risk of premature failure compared to aftermarket alternatives.

3. **Easy Installation** Since it is a direct replacement, the roll valve should fit without extensive modifications. Most owners report straightforward installation, though some basic tools (like a socket set and possibly a fuel line cutter) may be required.

4. **Compatibility with Classic Restorations** If you re restoring a vintage vehicle, using NOS parts helps maintain authenticity. The roll valve is a small but critical component that contributes to the original driving experience.

5. **Long-Term Reliability** Mopar NOS parts are built to last, reducing the need for frequent replacements. This can save time and money in the long run, especially if the vehicle is used for daily driving or enthusiast projects.

6. **Support for Classic Vehicle Communities** Purchasing NOS parts supports the preservation of classic car culture. Many enthusiasts prefer original or NOS components to maintain the integrity of their builds.

7. **No Guessing on Specifications** Unlike aftermarket parts that may vary in quality or fit, NOS parts are guaranteed to match the original specifications, ensuring proper function without compromises.

---

1. **Cost** NOS parts are typically more expensive than aftermarket alternatives. The Mopar 4002012 roll valve may cost significantly more than a generic replacement, which could be a barrier for budget-conscious buyers.

2. **Limited Availability** NOS inventory can be limited, especially for older or less common parts. This may require patience or additional searching to locate the exact item needed.

3. **Potential for Counterfeit or Mismatched Parts** While Mopar NOS parts are generally legitimate, there is a risk of purchasing counterfeit or mislabeled items, particularly from third-party sellers. Always verify the seller s reputation and authenticity.

4. **No Warranty on Used NOS Parts** Strictly speaking, NOS parts are "new" but were previously owned. Some sellers may offer limited warranties, but coverage is often less robust than with new OEM parts from a dealership.

5. **Storage and Handling Considerations** If the part has been stored for an extended period, it may require inspection for signs of wear, corrosion, or damage before installation. Some NOS parts may need cleaning or lubrication to ensure optimal performance.

6. **Not Always the Most Up-to-Date Design** While NOS parts are excellent for authenticity, they may not incorporate modern improvements or safety enhancements that newer OEM parts might include. However, for classic vehicles, this is rarely a concern.

7. **Potential for Overpaying** Some buyers may pay a premium for the NOS designation without fully understanding the value. If the part is no longer in production, the price may be inflated due to scarcity.

The Mopar 4002012 NOS roll valve is an excellent choice for enthusiasts restoring or maintaining a 1976 199 Chrysler, Plymouth, or Dodge CJ8 with the original fuel tank. Its authenticity, reliability, and ease of installation make it a strong candidate for those prioritizing quality and historical accuracy. However, the higher cost and potential availability issues may deter buyers on a tight budget or those willing to compromise on authenticity for affordability.

For most classic car owners who value original or near-original components, the NOS roll valve is a worthwhile investment. It ensures proper function, reduces long-term hassles, and contributes to the overall integrity of the vehicle. If budget is a concern, comparing the cost against the potential savings from aftermarket alternatives (in terms of reliability and fit) is advisable.
