Review MOPAR Dodge Truck Nos In Cab Fuel Tank Filler Tube fits 1972–1977

The **Mopar 3633209 Fuel Tank Filler Tube** is a precision-engineered replacement component designed specifically for **1972 through 1977 Dodge NOS (New Old Stock) vehicles**, including models like the **Dart, Coronet, Charger, Challenger, and Monaco**, as well as certain **Plymouth** variants from the same era. Crafted from high-quality **steel and durable rubber components**, this filler tube ensures a secure, leak-free connection between the fuel tank and the vehicle s fuel system, maintaining optimal performance and safety. The tube features a **metallic clamp mechanism** that securely fastens to the tank s inlet, preventing fuel vapor leaks while allowing for easy installation or removal when servicing the fuel system. Its **smooth, reinforced interior** minimizes the risk of clogging from debris, ensuring a consistent fuel flow to the engine. This part is a direct-fit replacement, meaning no modifications or additional adapters are required, making it an ideal choice for restorers, mechanics, and enthusiasts looking to maintain the original integrity of their classic muscle cars. Whether restoring a show-worthy vehicle or addressing a worn-out original component, the **Mopar 3633209** delivers the reliability and authenticity expected from a genuine aftermarket part, ensuring a seamless fit and long-lasting functionality.

**Pros and Cons of buying a Mopar Part Number 3633209 (Fuel Tank Filler Tube for 1972 1977 Dodge NOS)**

### **Pros**

1. **Direct Fitment** This part is specifically designed for 1972 1977 Dodge NOS (New Observation Sedan) models, ensuring compatibility without modifications. It replaces the original filler tube, which may have worn out or been damaged over time.

2. **Reliability** Mopar (Chrysler s aftermarket brand) is known for producing high-quality, durable parts that meet or exceed OEM standards. The filler tube is likely made from sturdy materials resistant to corrosion and wear.

3. **Easy Installation** The part is designed for straightforward replacement, requiring minimal tools and time. Most DIYers can install it without professional assistance, especially if they have basic mechanical experience.

4. **Cost-Effective** Compared to purchasing a complete fuel tank or a custom replacement, this part is relatively inexpensive. It s a targeted fix for a specific issue rather than a full system overhaul.

5. **Prevents Fuel Spills and Leaks** A failing filler tube can lead to fuel leaks, which pose fire hazards and environmental risks. Replacing it ensures a proper seal, reducing the risk of spills during refueling.

6. **Maintains Resale Value** Keeping the vehicle in good condition with original or OEM-quality parts can help maintain its value, especially if you plan to sell or trade it in later.

7. **Availability** Mopar parts are widely available through auto parts stores, online retailers, and dealerships, making it easy to source the part when needed.

### **Cons**

1. **Potential Counterfeit Parts** Some aftermarket parts, including Mopar items, may be counterfeit or low-quality if purchased from untrusted sellers. Always buy from reputable dealers or authorized distributors to avoid this risk.

2. **Limited Longevity Compared to OEM** While Mopar parts are high-quality, they may not last as long as genuine OEM parts if the vehicle is driven aggressively or exposed to harsh conditions (e.g., extreme temperatures, road salt).

3. **Mismatched Materials** In rare cases, the filler tube may not match the original material (e.g., rubber vs. plastic), which could lead to premature wear or sealing issues if the vehicle has a unique fuel system setup.

4. **Additional Labor Costs** If you re not comfortable with DIY repairs, hiring a mechanic to install the part will add to the total cost. Labor fees can vary but typically range from $50 to $150 depending on the shop.

5. **Compatibility Concerns** While the part is designed for your model, slight variations in fuel tank design (e.g., aftermarket modifications or rust damage) could make installation tricky. Always inspect the area before purchasing.

6. **Environmental and Safety Risks During Installation** Fuel tanks contain flammable liquids. If you re not experienced with fuel system work, there s a risk of spills or leaks during removal or installation, requiring caution and proper ventilation.

7. **Warranty Limitations** If the part fails shortly after purchase due to a manufacturing defect, Mopar s warranty may not cover it if the vehicle is no longer under factory warranty or if the part was installed incorrectly.

### **Conclusion**

The Mopar 3633209 fuel tank filler tube is a practical and reliable choice for replacing a worn or damaged part on your 1972 1977 Dodge NOS. Its direct fitment, durability, and ease of installation make it a sound investment for most owners. However, the potential for counterfeit parts, limited longevity compared to OEM components, and the need for careful installation (especially around fuel) are factors to consider.

If you re confident in your ability to perform the replacement safely and source the part from a trusted supplier, this is a cost-effective solution. For those less experienced, weighing the labor cost against the part s price is advisable.

### **Recommendation**

- **Buy from an authorized Mopar dealer or a well-reviewed online retailer** (e.g., RockAuto, Summit Racing, or your local auto parts store) to ensure authenticity.

- **Inspect the fuel tank area** before purchasing to confirm the part will fit without modifications.

- **Follow safety precautions** when working with fuel, such as draining the tank partially or using a fuel stabilizer if necessary.

- **Consider professional installation** if you re unsure about handling fuel or if the tank is corroded, as additional repairs (e.g., sealing leaks) may be needed.

- **Keep receipts and warranties** in case of defects, though Mopar s coverage may be limited for aftermarket vehicles.

For most owners, this part is a **strong, cost-effective choice** that balances quality and convenience. If budget allows, pairing it with a fuel tank cleaner or sealant during installation can further extend its lifespan.
