Review MERCEDES benz Fuel Gas Tank Reservoir Assembly Oem fits W212 E63S E63 AMG 2014–2016

The **Mercedes-Benz A2184700501 Fuel Gas Tank Reservoir (E63 AMG, W212, 2014 2016)** is a precision-engineered component designed to ensure optimal fuel delivery and system integrity within the high-performance E63 AMG S-Class sedan. This critical part serves as the primary reservoir for the fuel gas system, housing the fuel rail and injectors while maintaining structural stability under the demanding conditions of aggressive driving and high-performance applications. Crafted from high-grade, corrosion-resistant materials, the reservoir is engineered to withstand the thermal and mechanical stresses associated with the E63 s twin-turbocharged M279 V8 engine, which produces an impressive 510 612 horsepower depending on the model year and configuration. The design incorporates seamless integration with the fuel lines, pressure regulators, and fuel pump assembly, ensuring minimal resistance and maximum efficiency in fuel flow. This component is essential for maintaining consistent fuel pressure and preventing leaks, which could compromise engine performance or lead to costly repairs. Whether installed in a meticulously restored classic or a meticulously maintained daily driver, the A2184700501 reservoir is a vital part of preserving the E63 AMG s legendary power, responsiveness, and reliability. For enthusiasts seeking to restore or upgrade their vehicle s fuel system, this OEM-quality reservoir ensures compatibility with the original specifications, delivering the same level of precision and durability expected from Mercedes-Benz engineering.

### **Pros and Cons of Buying a Mercedes-Benz W212 E63 S AMG Fuel Gas Tank Reservoir (2014-2016, Part Number A2184700501)**

1. **Performance and Reliability** The E63 S AMG is a high-performance luxury sedan known for its powerful 6.2L V8 engine (producing around 503 513 hp in these models), which remains a strong and reliable powerplant if properly maintained. The fuel system, including the gas tank reservoir, is part of the vehicle s core fuel delivery mechanism, ensuring consistent performance.

2. **Aftermarket Availability** The W212 platform (2005 2013, with some 2014 2016 models) has a large aftermarket presence. This means parts like the fuel gas tank reservoir (A2184700501) are relatively easy to find, either new or refurbished, and often at competitive prices.

3. **Luxury and Comfort** Mercedes-Benz is synonymous with premium interiors, advanced driver aids, and refined ride quality. If you value luxury and driving dynamics, the E63 S AMG delivers an exceptional experience.

4. **Potential for Modifications** The E63 S AMG is a favorite among tuning communities. Upgrading the fuel system (including the gas tank reservoir) can improve fuel flow, especially if you plan to modify the engine for higher performance.

5. **Resale Value (Compared to Others)** While not as high as newer Mercedes models, the E63 S AMG retains decent resale value due to its reputation for performance and desirability among enthusiasts.

6. **Durability of the Fuel System** The original gas tank reservoir (A2184700501) is designed to last the lifespan of the vehicle if there are no leaks, cracks, or contamination issues. Replacing it with an OEM or high-quality aftermarket part can prevent future fuel-related problems.

7. **Compatibility with Other Mods** If you re upgrading other components (e.g., fuel injectors, fuel pump, or ECU tuning), replacing the gas tank reservoir ensures the entire system works harmoniously.

1. **Age and Wear** The 2014 2016 W212 models are now over a decade old. While the E63 S AMG is robust, older vehicles may require more frequent maintenance, especially if the fuel system hasn t been serviced recently. Rust, degraded seals, or fuel line failures can occur over time.

- **Fuel pump failures** (common in AMG models due to high power demands).

- **Leaking fuel lines or injectors** (especially if the vehicle has been modified).

- **Contaminated fuel** (if old fuel sits in the tank for extended periods).

The gas tank reservoir (A2184700501) itself may develop cracks or leaks if the tank is old or improperly installed.

3. **Cost of Replacement** While the part (A2184700501) is reasonably priced (typically $100 $300 for an aftermarket or OEM equivalent), labor costs for replacement can add up, especially if the tank needs to be removed due to rust or other issues.

4. **Potential for Counterfeit Parts** Due to the aftermarket s popularity, there is a risk of purchasing low-quality or counterfeit fuel system components. Always buy from reputable suppliers (e.g., Amazon, RockAuto, or Mercedes-Benz approved dealers) to avoid issues.

5. **Environmental and Safety Concerns** Fuel tanks, especially older ones, can develop leaks, posing a fire or contamination risk. Proper disposal of old fuel tanks is also important due to environmental regulations.

6. **Compatibility with Modern Tuning** If you plan to heavily modify the engine (e.g., forced induction, turbo upgrades), the stock gas tank reservoir may not handle the increased fuel demand. Upgrading to a larger or high-flow reservoir (e.g., from companies like **BMS, FuelTech, or AMG Performance**) may be necessary.

7. **Maintenance Overhead** Unlike newer vehicles with advanced diagnostics, troubleshooting fuel system issues on an older AMG can be time-consuming and may require specialized tools or knowledge.

The **Mercedes-Benz W212 E63 S AMG fuel gas tank reservoir (A2184700501)** is a **practical and necessary upgrade** if you own or plan to modify one of these high-performance sedans. The part itself is **reliable and widely available**, making it a smart choice for maintaining or enhancing fuel delivery efficiency.

However, **buying this part should be part of a broader maintenance or modification strategy**. If your vehicle has **high mileage, signs of fuel system wear, or you plan aggressive tuning**, replacing the reservoir is a **proactive step** to prevent future failures. Conversely, if the vehicle is **well-maintained and used for daily driving without modifications**, the stock reservoir may suffice for now but monitoring for leaks or performance drops is crucial.

- **Proceed with the replacement** if you notice **fuel delivery issues, spills, or poor engine performance**. A **high-quality aftermarket or OEM replacement** (e.g., **BMS, FuelTech, or Mercedes-Benz genuine**) is ideal.

- **Inspect the entire fuel system** (lines, pump, injectors) during replacement to catch any hidden problems.

- **Upgrade to a high-flow gas tank reservoir** (e.g., **AMG Performance or BMS**) to handle increased fuel demands.

- **Consider a full fuel system refresh** (pump, lines, injectors) to ensure compatibility with modifications.

- **Get a pre-purchase inspection** (especially of the fuel system) before buying the part.

- **Check for rust, leaks, or fuel contamination** these can indicate deeper issues beyond just the reservoir.

- **OEM (Mercedes-Benz genuine)** Most reliable but expensive.

- **Aftermarket (BMS, FuelTech, RockAuto)** Good balance of quality and cost.

- **Avoid unknown sellers** to prevent counterfeit or low-quality parts.

- You own an E63 S AMG and need to **replace a failing reservoir**.

- You plan **modifications that require better fuel flow**.

- You want to **prevent future fuel system failures**.

- The vehicle is **already showing severe fuel system issues** (e.g., pump failure, major leaks) that require more than just the reservoir.

- You **lack mechanical knowledge** to properly install or diagnose related problems.

Treat this as part of a **larger maintenance or upgrade plan**. If done correctly, replacing the gas tank reservoir will **extend the life of your E63 S AMG s fuel system** and ensure optimal performance whether stock or modified.
