Review RADIUM ENGINEERING Fuel Hanger Surge Tank Add on Nissan S14/s15/r33/r34

The **Radium Engineering 20-0700 Fuel Hanger Surge Tank Add-On** is a meticulously engineered aftermarket component designed to enhance the performance, reliability, and longevity of the fuel system in Nissan s iconic S14 (Fairlady Z), S15 (Skyline GT-R), R33 (Skyline GT-R), and R34 (Skyline GT-R) models. This precision-crafted add-on is specifically tailored to address the inherent limitations of the stock fuel delivery system, which can suffer from fuel starvation, inconsistent pressure, and vapor lock under high-performance driving conditions. By integrating a dedicated surge tank into the fuel line, this system effectively mitigates these issues by providing a reservoir for excess fuel vapor and air, ensuring a steady and uninterrupted fuel supply to the engine even during aggressive throttle inputs, hard acceleration, or prolonged high-load scenarios. The surge tank operates by separating fuel vapor from liquid fuel, preventing vapor lock and allowing the engine to maintain optimal fuel pressure without relying solely on the stock fuel pump s capacity. Constructed from high-quality materials, including durable plastic and reinforced fittings, the Radium Engineering add-on is built to withstand the demands of high-performance applications while maintaining compatibility with stock and upgraded fuel systems. Installation is straightforward, requiring minimal modifications to the existing fuel line setup, and the system is designed to integrate seamlessly with aftermarket fuel pumps, fuel rail pressure sensors, and other performance-oriented upgrades. Whether you re pushing the limits of your S14 s 2.0L or the R34 s 2.8L twin-turbo V6, this surge tank add-on ensures that fuel delivery remains consistent, reducing the risk of hesitation, stalling, or catastrophic fuel system failure. Ideal for drift enthusiasts, track-day drivers, and those seeking to maximize power output, the Radium Engineering 20-0700 is a proven solution for those who demand reliability without compromise.

### **Pros and Cons of the Radium Engineering 20-0700 Fuel Hanger Surge Tank Add-On for Nissan S14/S15/R33/R34**

#### **Pros**

1. **Improved Fuel Delivery Under Load** The surge tank helps maintain consistent fuel pressure during aggressive driving, high throttle inputs, or hard acceleration, reducing the risk of fuel starvation in high-performance applications.

2. **Better Fuel Pump Longevity** By reducing pressure fluctuations, the surge tank can help prevent premature wear on the fuel pump and related components.

3. **Enhanced Performance in Modified Engines** For turbocharged or high-compression builds, the surge tank mitigates fuel delivery issues that can arise from increased demand.

4. **Retrofits Easily** Designed specifically for the Nissan S14/S15/R33/R34 platforms, the installation is straightforward and doesn t require major modifications.

5. **Cost-Effective Upgrade** Compared to full fuel system overhauls or high-end aftermarket solutions, this is a relatively affordable solution for common fueling issues.

6. **Reduces Fuel Line Vibration** Helps dampen pulsations in the fuel line, which can improve overall system reliability.

7. **Works with Stock and Modified Fuel Pumps** Compatible with both stock and upgraded fuel pumps, making it versatile for different builds.

#### **Cons**

1. **Not a Cure for All Fueling Issues** If the fuel pump itself is failing or the fuel pressure regulator is malfunctioning, this add-on may not fully resolve the problem.

2. **Minimal Performance Gain in Stock Applications** On stock engines with no major modifications, the benefits may be negligible unless driving aggressively or in high-demand situations.

3. **Requires Proper Installation** Improper routing or installation (e.g., air bubbles in the line) can negate its effectiveness or even cause new issues.

4. **Additional Component to Maintain** Introduces one more part that could potentially leak or fail over time, requiring periodic inspection.

5. **Limited Compatibility with Extreme Mods** In highly modified builds (e.g., extreme turbo setups, large injectors, or aggressive fueling systems), a more robust solution (like a full fuel rail or upgraded pump) may still be needed.

6. **Potential for Overkill on Mild Builds** If the engine is only lightly modified, the cost may not justify the marginal improvement in fuel delivery.

7. **May Not Fit All Fuel System Configurations** Some aftermarket fuel setups (e.g., custom fuel rails, high-flow pumps) might require additional modifications to integrate the surge tank properly.

### **Conclusion**

The **Radium Engineering 20-0700 Fuel Hanger Surge Tank** is a **practical and affordable solution** for Nissan S14/S15/R33/R34 owners experiencing fuel delivery issues under load, particularly in modified or high-performance applications. It excels in **reducing fuel starvation, improving fuel pump longevity, and smoothing out fuel pressure fluctuations**, making it a worthwhile upgrade for **turbocharged, high-compression, or heavily modified engines**.

However, for **stock or lightly modified vehicles**, the benefits may be **minimal**, and the cost may not be justified unless fueling problems are already present. Additionally, it is **not a standalone fix** for failing fuel pumps or regulator issues it works best as part of a **comprehensive fuel system upgrade**.

---

### **Recommendation**

- You have a **modified engine (turbo, high compression, forced induction)** and experience **fuel starvation, hesitation, or rough idle under load**.

- You want to **extend the life of your fuel pump** and improve reliability in high-demand driving scenarios.

- You re already running **aftermarket fuel components** (e.g., upgraded pump, larger injectors) and need better fuel delivery stability.

- Your engine is **stock or only mildly modified** and runs smoothly without fueling issues.

- You re on a **tight budget** and can t justify the cost for minimal gains.

- You ve already confirmed that **fuel pump or regulator failure** is the root cause (in which case, a replacement is needed).

**Final Verdict:** A **solid mid-range upgrade** for performance builds, but not essential for stock or lightly modified cars. If fuel delivery is a concern in your setup, it s a **reliable and easy-to-install solution** worth considering.
