The **NS55P2** fuel tank is a popular aftermarket replacement for the stock fuel tank in the 1985-1989 Toyota 4Runner, particularly for those looking to improve fuel capacity, reduce weight, or enhance performance. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
---
### **Pros of the NS55P2 Fuel Tank**
1. **Increased Fuel Capacity** The NS55P2 holds approximately **25 gallons**, compared to the stock tank s **23-24 gallons**, providing a modest but noticeable increase in range. This is especially useful for long-distance off-roading or overlanding.
2. **Lightweight Construction** Made from aluminum, the NS55P2 is significantly lighter than the stock steel tank (which can weigh around 50-60 lbs). This reduction in weight can improve fuel economy slightly and reduce overall vehicle weight, potentially enhancing acceleration and handling.
3. **Improved Fuel Flow and Efficiency** The design of the NS55P2 is optimized for better fuel delivery, reducing the risk of fuel starvation during aggressive driving or off-road use. Some users report smoother engine performance, particularly in high-demand situations.
4. **Durability and Corrosion Resistance** Aluminum resists corrosion better than steel, which is beneficial in environments where salt, moisture, or harsh chemicals are present. This can extend the lifespan of the tank and prevent leaks over time.
5. **Compatibility with Modifications** The NS55P2 is designed to fit standard 4Runner fuel systems, including the stock fuel pump and lines. It is also compatible with aftermarket fuel pumps and upgrades, making it a versatile choice for modified vehicles.
6. **Easier Installation** While installation requires some mechanical skill, the NS55P2 is generally considered straightforward to install, especially for those familiar with basic automotive work. The kit typically includes all necessary hardware and instructions.
7. **Aesthetic Appeal** The sleek, modern look of the aluminum tank can enhance the appearance of a heavily modified or restored 4Runner, especially when paired with other aftermarket components.

### **Cons of the NS55P2 Fuel Tank**
1. **Higher Upfront Cost** The NS55P2 is more expensive than the stock tank, typically ranging between **$300 and $500**, depending on the retailer and additional components included. This cost can be prohibitive for budget-conscious buyers.
2. **Potential for Leaks or Weaknesses** While aluminum is corrosion-resistant, it is not immune to damage from sharp objects or improper handling. Some users report that the tank can dent or crack if struck hard, particularly in off-road conditions. Additionally, the welds or seams in some aftermarket tanks have been known to fail over time if not properly maintained.
3. **Compatibility Issues with Some Modifications** If the vehicle has been heavily modified (e.g., with a turbocharged engine, large fuel injectors, or a high-flow fuel pump), the stock fuel system may struggle to keep up with the increased demand. While the NS55P2 improves capacity, it does not inherently upgrade the fuel delivery system, so additional modifications (like a high-capacity fuel pump) may still be necessary.
4. **Installation Complexity** While the NS55P2 is designed for ease of installation, it requires careful attention to detail. Improper installation can lead to fuel leaks, electrical issues, or even fire hazards. Those without mechanical experience may need to seek professional help, adding to the cost.
5. **Potential for Fuel Sloshing** The larger capacity can cause more fuel sloshing during sharp turns or off-road maneuvers, which may affect fuel delivery and engine performance. Some users report occasional fuel starvation or rough idling as a result.
6. **Limited Availability of Parts** Aftermarket aluminum tanks like the NS55P2 may not have as many readily available replacement parts or accessories as the stock steel tank. This could make repairs or upgrades more difficult in the long run.
7. **Potential for Voiding Warranty** If the vehicle is still under manufacturer warranty, installing an aftermarket fuel tank may void certain coverage, particularly if the modification is deemed "non-standard" by the dealership or Toyota.

### **Conclusion**
The **NS55P2 fuel tank** is a solid choice for 1985-1989 Toyota 4Runner owners who prioritize increased fuel capacity, weight reduction, and improved durability over cost savings. It excels in scenarios where range, off-road capability, or corrosion resistance is critical, and it integrates well with most stock and aftermarket fuel systems. However, the higher upfront cost, potential for installation errors, and risks of physical damage must be carefully considered.
For owners who are primarily concerned with reliability and do not require the extra capacity, the stock tank may be sufficient. Conversely, those planning extensive off-roading, overlanding, or performance modifications will likely benefit significantly from the NS55P2.

### **Recommendation**
**Install the NS55P2 if:**- You frequently drive long distances or engage in off-roading where extra fuel capacity is advantageous.
- You want to reduce vehicle weight for better performance or fuel efficiency.
- You operate in corrosive environments (e.g., coastal areas, salted roads) and prefer a tank that resists rust.
- You are comfortable with mechanical work or have access to a professional installer.
**Avoid the NS55P2 if:**- You are on a tight budget and the stock tank meets your needs.
- Your vehicle has been heavily modified with a high-performance fuel system that requires additional upgrades (e.g., a high-flow fuel pump).
- You are not confident in your ability to install the tank correctly, as improper installation can lead to serious issues.
- You prioritize warranty coverage and are unwilling to risk voiding it.
**Final Verdict:** The NS55P2 is a worthwhile upgrade for most 1985-1989 4Runner owners who want to enhance their vehicle s capabilities without sacrificing too much in terms of reliability. Pair it with a high-quality fuel pump and proper installation to maximize its benefits.
