**Pros and Cons of buying a Spectra FN1139 Fuel Tank Filler Neck**
The Spectra FN1139 is a popular aftermarket fuel tank filler neck designed for various applications, including trucks, SUVs, and off-road vehicles. Below is a detailed breakdown of its advantages and disadvantages.
### **Pros**
1. **Durability and Weather Resistance** The Spectra FN1139 is constructed from high-quality, UV-resistant polypropylene, making it resistant to cracking, fading, and degradation from exposure to sunlight, rain, and extreme temperatures. This ensures a longer lifespan compared to some cheaper alternatives.
2. **Compatibility with Multiple Applications** This filler neck is designed to fit a wide range of vehicles, including Ford F-Series trucks, Chevy Silverado/GMC Sierra, Ram 1500, and other full-size trucks and SUVs. It is also commonly used in off-road and custom builds where stock filler necks may not suffice.
3. **Easy Installation** The Spectra FN1139 is designed for straightforward installation, often requiring minimal modifications. It typically includes mounting hardware, and many users report that it can be installed in a few hours with basic tools. The included gasket ensures a secure seal without excessive effort.
4. **Improved Fuel Flow and Reduced Spillage** The design of the Spectra FN1139 helps minimize fuel splashing and spillage during refueling, which can be particularly beneficial in off-road or high-use applications where fuel containment is a concern.
5. **Aesthetic Appeal** The filler neck comes in a sleek, modern design that can enhance the appearance of a vehicle, especially when paired with custom fuel caps or trim. It is available in matte black, which is a popular choice for many builds.
6. **Corrosion Resistance** Unlike some metal filler necks, the Spectra FN1139 does not rust, making it ideal for vehicles exposed to salt, moisture, or harsh environments.
7. **Positive User Feedback** Many reviews from customers highlight reliability, ease of installation, and long-term performance. It is often recommended in forums and online communities for its balance of quality and affordability.
8. **Compatibility with Aftermarket Fuel Systems** The Spectra FN1139 works well with aftermarket fuel pumps, lines, and other modifications, making it a versatile choice for custom fuel systems.

### **Cons**
1. **Limited Color Options** While the Spectra FN1139 is available in matte black, some buyers may prefer other colors (e.g., gray, silver, or custom finishes) that are not offered as standard options.
2. **Potential Fitment Issues** Although the Spectra FN1139 is designed for a broad range of vehicles, fitment can vary slightly depending on the specific model and year. Some users may need to adjust mounting brackets or use spacers to achieve a perfect fit. Always verify compatibility with your vehicle s make, model, and year before purchasing.
3. **Price Point** While the Spectra FN1139 is reasonably priced compared to some high-end aftermarket parts, it may still be more expensive than generic or no-name filler necks. However, the quality justifies the cost for most buyers.
4. **Fuel Cap Compatibility** The Spectra FN1139 is designed to work with standard fuel caps, but some users may need to purchase a compatible aftermarket cap for an improved look or additional features (e.g., locking mechanisms). Ensure the cap you choose matches the thread size and style of the filler neck.
5. **Installation May Require Modifications** In some cases, minor modifications to the fuel tank or surrounding area may be necessary to accommodate the Spectra FN1139, such as trimming excess material or adjusting mounting points. This is not unique to this product but is a common consideration with aftermarket parts.
6. **Availability of Alternatives** While Spectra is a well-regarded brand, there are other high-quality filler necks from competitors (e.g., Flowmaster, ACDelco, or local manufacturers) that may offer slight variations in design or pricing. Researching alternatives can help ensure you are getting the best option for your specific needs.

### **Conclusion**
The Spectra FN1139 fuel tank filler neck is a well-rounded product that excels in durability, ease of installation, and compatibility with a wide range of vehicles. Its resistance to weather, corrosion, and wear makes it a reliable choice for both daily drivers and off-road applications. While it may not offer the widest color selection or require minor adjustments for perfect fitment in some cases, its overall performance and positive user feedback outweigh these minor drawbacks for most buyers.
For those seeking a high-quality, long-lasting filler neck that balances functionality and aesthetics, the Spectra FN1139 is a strong recommendation. It is particularly well-suited for truck and SUV owners, off-road enthusiasts, and anyone looking to upgrade their fuel system with a durable, modern component.
### **Recommendation**
If you are replacing a stock filler neck or upgrading your vehicle s fuel system, the Spectra FN1139 is an excellent choice. Before purchasing, verify that it is compatible with your specific vehicle model and year, and consider whether you need additional accessories like a custom fuel cap. For most applications, the Spectra FN1139 will provide years of trouble-free service with minimal maintenance.
