### **Pros and Cons of buying a Porsche 911 Fuel Tank (Part No. 911.201.904.00 Dan Fuel Tank for 1965 1973 911s)**
#### **Pros:**1. **Authentic Fitment** This is a genuine Dan Industries fuel tank, designed specifically for the 1965 1973 911 series. It ensures a perfect fit without modifications, preserving the car s original integrity.
2. **High-Quality Construction** Dan Industries is known for producing durable, corrosion-resistant fuel tanks. The material used is typically aluminum or a high-grade plastic, which is less prone to degradation compared to original rubber or early plastic tanks.
3. **Improved Safety** The original fuel tanks from this era were prone to cracking, leaking, or failing due to age, fuel quality, or road debris. A new Dan tank eliminates these risks, reducing the chance of fuel spills or fire hazards.
4. **Compatibility with Modern Fuel** Older tanks were not designed for modern fuel additives or ethanol blends, which can degrade rubber and plastic over time. A new Dan tank is built to handle contemporary fuel without premature failure.
5. **Easier Installation** While installation still requires some mechanical skill, Dan tanks come with clear instructions and are designed to fit modern 911s without major modifications (though wiring and mounting points may need attention).
6. **Long-Term Reliability** A new tank eliminates the uncertainty of an aging original part. With proper maintenance, it can last the lifetime of the car, reducing the risk of unexpected failures.
7. **Enhanced Performance** Some owners report slight improvements in fuel delivery and engine performance after replacing an old, clogged, or leaking tank.
8. **Resale Value Preservation** Restoring a 911 with original components can be costly. Replacing a failed fuel tank with an aftermarket part like the Dan tank is often cheaper than sourcing an original and can make the car more appealing to buyers who prioritize reliability over authenticity.

#### **Cons:**1. **Cost** A new Dan fuel tank is significantly more expensive than a used or salvaged original tank. Prices typically range between **$800 $1,500**, depending on the seller and additional components (e.g., fuel pump, sender unit, or wiring harness).
2. **Installation Complexity** While not extremely difficult, installing a fuel tank requires careful handling of fuel lines, wiring, and mounting brackets. It may also involve removing the rear seat, floor mats, and possibly the rear bumper. Owners without mechanical experience may need to pay for professional installation, adding to the cost.
3. **Wiring and Compatibility Issues** Some Dan tanks come with updated wiring or sender units that may not match the original 911 s gauge or computer systems. Retrofitting may require additional modifications or the purchase of compatible gauges or ECU updates.
4. **Ethanol Concerns** While Dan tanks are generally ethanol-compatible, some owners report that long-term exposure to high-ethanol fuels (e.g., E30 ) can still cause swelling or degradation in plastic components. This is less of an issue with aluminum tanks but requires monitoring.
5. **Originality vs. Restoration Purists** Some 911 enthusiasts prefer to use original components or period-correct replacements to maintain the car s historical accuracy. A Dan tank, while functional, is not an original part and may not appeal to collectors focused on 100% authenticity.
6. **Potential for Counterfeit Parts** The aftermarket for 911 parts has seen an increase in counterfeit or low-quality replicas. Buyers should purchase from reputable sellers (e.g., Porsche Parts Direct, Dan Industries official distributors, or trusted 911 specialists) to avoid receiving substandard or unsafe products.
7. **Additional Costs** Beyond the tank itself, owners may need to replace:- Fuel pump (if the original is failing)
- Fuel sender unit (if the gauge is not compatible)
- Fuel lines or clamps
- Mounting brackets or brackets (if worn)
- Wiring harness or connectors
These extras can push the total cost closer to **$1,500 $2,500** depending on the car s condition.
8. **Time-Consuming Project** For a weekend warrior, this is a multi-day project. It requires draining the fuel system, disconnecting components, and ensuring no fuel residue is left behind (to avoid fire hazards during installation).

### **Conclusion:**Replacing the fuel tank in a 1965 1973 911 with a **Dan Industries part (911.201.904.00)** is a **highly recommended upgrade** for most owners, especially those who prioritize reliability, safety, and long-term ownership. The risks of a failing original tank such as fuel leaks, engine stalls, or fire hazards far outweigh the drawbacks of the aftermarket part. The Dan tank is a well-engineered, durable solution that modernizes a critical safety component without sacrificing performance.
However, the decision should be weighed against budget constraints and personal priorities:- If **originality is paramount**, sourcing a used original tank (if available) or accepting the risks of the existing tank may be preferable.
- If **reliability and peace of mind** are the top concerns, the Dan tank is the clear choice, despite the higher upfront cost.
- For **budget-conscious buyers**, a used original tank (if found in good condition) or a lower-cost aftermarket alternative (e.g., a non-Dan aluminum tank) could be considered, though with increased risk.
