**Pros and Cons of Buying a BMW 16-11-7-220-745 Fuel Tank**

The BMW 16-11-7-220-745 fuel tank is a part commonly associated with the E38 7 Series (1994 2001), specifically the M7 (745i) variant. Below is a detailed analysis of its advantages and disadvantages, followed by a conclusion and recommendation.

---

### **Pros**

1. **Compatibility and Fitment**

- This fuel tank is designed specifically for the BMW E38 7 Series, ensuring a perfect fit without modifications. It is commonly used in restorations or replacements for original tanks that may have failed or been damaged.

- The 745i model often requires high-quality parts due to its performance-oriented nature, and this tank is a reliable choice for maintaining authenticity or improving fuel system integrity.

2. **Durability and Build Quality**

- BMW s fuel tanks from this era were constructed with sturdy materials, including reinforced plastic and metal components, which were designed to withstand the stresses of high-performance driving and long-term use.

- The tank s design reduces the risk of leaks or cracks, especially if it is an original or high-quality aftermarket replacement.

3. **Performance Considerations**

- A properly functioning fuel tank ensures consistent fuel delivery to the engine, which is critical for maintaining the 745i s power output and reliability. A failing tank can lead to fuel starvation, stalling, or even engine damage.

- Some aftermarket versions of this tank may incorporate improvements such as better sealing or corrosion resistance, which can enhance longevity compared to original units.

4. **Availability of Parts and Support**

- The E38 platform is a well-documented model, and parts like this fuel tank are widely available through BMW specialty shops, online marketplaces, and aftermarket suppliers. This makes sourcing and installation relatively straightforward.

- The community of E38 enthusiasts is active, offering forums, guides, and troubleshooting support for common issues, including fuel system problems.

5. **Aesthetic and Restoration Value**

- For collectors or restorers, using an original or high-quality replica tank preserves the vehicle s authenticity. This can be particularly valuable if the goal is to maintain or increase the car s resale or show value.

- The tank s design aligns with the 7 Series luxury and performance aesthetic, making it a desirable component for enthusiasts who prioritize both function and form.

---

### **Cons**

1. **Age and Potential Wear**

- The E38 7 Series is now over 25 years old, and original fuel tanks may exhibit signs of aging, such as cracks, corrosion, or degraded seals. Even if the tank appears intact, prolonged exposure to fuel, heat, and road debris can compromise its integrity.

- Over time, the plastic components may become brittle, increasing the risk of failure during installation or use.

2. **Corrosion and Rust**

- Older BMWs, especially those driven in harsh climates or exposed to road salt, are prone to corrosion. The fuel tank s metal components or welds may rust, leading to leaks or structural weaknesses.

- Rust can be difficult to detect internally until the tank fails, which can result in sudden fuel leaks or contamination.

3. **Cost of Replacement**

- While the fuel tank itself may not be extremely expensive (typically ranging from $200 to $600 depending on quality and source), labor costs for installation can add up, especially if the job requires additional work such as rerouting fuel lines or replacing related components like the fuel pump or sender unit.

- For enthusiasts restoring a high-end model like the 745i, the cumulative cost of replacing or upgrading multiple components (including the fuel tank) can be significant.

4. **Compatibility with Modern Fuel Standards**

- Modern fuels often contain additives or higher ethanol blends that can degrade plastic components over time. While this tank was designed for fuels available in the 1990s, prolonged exposure to contemporary fuel may accelerate wear or cause compatibility issues.

- Some aftermarket tanks may not be explicitly rated for modern fuel standards, which could pose long-term risks.

5. **Installation Complexity**

- Replacing a fuel tank in an E38 7 Series requires careful disassembly of surrounding components, including the fuel lines, sender unit, and sometimes the fuel pump. This process can be time-consuming and may require specialized tools or expertise.

- Improper installation can lead to leaks, air in the fuel line, or damage to adjacent systems, such as the fuel rail or injectors.

6. **Risk of Counterfeit or Low-Quality Parts**

- The aftermarket for BMW parts is vast, and there is a risk of purchasing a counterfeit or poorly manufactured fuel tank. Low-quality tanks may fail prematurely, leak, or not fit correctly, leading to further complications.

- It is essential to source parts from reputable suppliers with good reviews and warranties to mitigate this risk.

7. **Environmental and Safety Concerns**

- Fuel tanks, especially older ones, may contain residual fuel or contaminants that can pose environmental or safety hazards during handling or disposal. Proper ventilation and disposal methods are required to avoid spills or fires.

- If the tank has been previously damaged or repaired, there may be hidden risks such as residual stress or weak welds that could fail unexpectedly.

---

### **Conclusion**

The BMW 16-11-7-220-745 fuel tank is a practical and widely available component for the E38 7 Series, particularly the 745i model. Its primary advantages lie in its compatibility, durability, and the support available from the BMW enthusiast community. For owners seeking to restore or maintain their vehicle s performance and authenticity, this tank offers a reliable solution. However, potential buyers must weigh these benefits against the risks associated with the tank s age, potential corrosion, installation complexity, and the cost of labor. Additionally, sourcing high-quality parts and ensuring proper installation are critical to avoiding future issues.

For collectors or restorers, the tank s value extends beyond mere functionality it contributes to the vehicle s historical accuracy and resale potential. For performance-focused drivers, a well-maintained or upgraded fuel tank ensures consistent fuel delivery, which is vital for the 745i s power output and reliability.

### **Recommendation**

1. **Source the Part Carefully**

- Purchase the fuel tank from a trusted supplier, such as a BMW specialty shop, a well-reviewed online retailer, or a reputable aftermarket brand known for quality. Avoid overly cheap options that may be counterfeit or poorly made.

- If restoring an original E38, consider using an original or high-quality OEM replacement to preserve the vehicle s value.

2. **Inspect for Damage**

- Before installation, thoroughly inspect the tank for signs of corrosion, cracks, or leaks. If the tank has been previously damaged or repaired, proceed with caution or opt for a new unit.

- Check the fuel lines, sender unit, and fuel pump for wear or failure, as these components are often replaced simultaneously with the tank.

3. **Professional Installation**

- While experienced DIYers may attempt the installation, replacing a fuel tank in an E38 7 Series can be complex. If unsure, consult a professional mechanic or BMW specialist to ensure proper installation and avoid common pitfalls such as air in the fuel line or improper sealing.

- Consider upgrading related components (e.g., fuel pump, sender unit, or fuel lines) during the process to improve long-term reliability.

4. **Maintain the Fuel System**

- Regularly check the fuel system for leaks, corrosion, or performance issues. Use high-quality fuel additives to protect the tank and lines from degradation over time.

- Monitor the fuel sender unit and ensure it is functioning correctly to avoid issues with the fuel gauge or fuel management system.

5. **Balance Cost and Value**

- Weigh the cost of the fuel tank against the overall restoration or maintenance budget. While the tank itself may be affordable, labor and additional components can add up. Prioritize spending on critical upgrades that directly impact performance or reliability.

- If the vehicle is intended for daily driving, focus on durability and ease of maintenance. If it is a collector s item, prioritize authenticity and long-term preservation.

The BMW 16-11-7-220-745 fuel tank is a sound choice for E38 7 Series owners, particularly those restoring or maintaining a 745i. With careful sourcing, thorough inspection, and professional installation, it can significantly enhance the vehicle s reliability and performance. However, buyers should be mindful of the tank s age-related risks and the importance of supporting components. For most enthusiasts, the benefits outweigh the drawbacks, making it a worthwhile investment.
