### **Pros and Cons of buying a Auto 890-4073-20 20-Gallon Gas Tank for 1973 1981 GM C/K Trucks**

#### **Pros:**

1. **Increased Fuel Capacity** The 20-gallon tank provides a significant fuel range improvement over the stock 12 15-gallon tanks found on many older GM C/K trucks, reducing the frequency of refueling stops, especially on long trips or in remote areas.

2. **Better Fuel Efficiency on Long Hauls** With more fuel capacity, you can carry extra fuel for backup or emergencies, which is useful for off-road use, towing, or extended travel without needing frequent stops.

3. **Compatibility with Aftermarket Modifications** Many modern trucks and performance builds require larger fuel tanks to support higher fuel consumption, especially with turbocharged engines, larger engines, or heavy-duty applications.

4. **Durability and Quality** Auto 890 is a reputable manufacturer known for producing reliable fuel tanks for classic and performance vehicles. Their tanks are typically made from high-quality materials and designed to withstand the stresses of off-road use or heavy-duty applications.

5. **Easier Installation** The tank is designed specifically for 1973 1981 GM C/K trucks, meaning it should fit without major modifications to the frame or fuel lines, assuming the vehicle s fuel system is compatible.

6. **Reduced Fuel Stop Frequency** For daily drivers or those who frequently travel long distances, a larger tank means fewer trips to the gas station, which can be convenient and time-saving.

7. **Potential for Increased Resale Value** If you plan to restore or modify your truck, a larger fuel tank can be seen as a desirable upgrade, potentially increasing its value in the classic truck market.

#### **Cons:**

1. **Limited Stock Availability** Aftermarket parts, especially for older GM trucks, can be difficult to source. You may need to order from a specialty supplier, which could take time or require shipping costs.

2. **Potential Weight Increase** A 20-gallon tank is significantly heavier than a stock 12-gallon tank, which could slightly reduce fuel economy due to the added weight. However, this is usually negligible compared to the benefits of increased range.

3. **Compatibility Issues with Stock Fuel Lines** While the tank is designed for your truck, you may need to adjust or replace fuel lines, fittings, or the fuel pump to ensure a proper fit. This could add to the cost or complexity of installation.

4. **Cost** The price of a high-quality aftermarket fuel tank like the Auto 890 can be higher than a basic replacement part. You ll also need to factor in labor (if installing professionally) or additional materials (fuel lines, clamps, etc.).

5. **Potential for Leaks or Damage** Fuel tanks, especially in older vehicles, can develop leaks or corrosion over time. While the Auto 890 is durable, improper installation or rough handling during installation could lead to issues.

6. **Reduced Cargo Space** If your truck has a bed that s already tight on space, a larger fuel tank may take up room that could otherwise be used for cargo or tools. This is less of an issue in larger C/K beds but worth considering.

7. **Mileage Impact (Minor)** While not significant, carrying more fuel can slightly reduce the truck s overall fuel efficiency due to the extra weight. However, this is usually outweighed by the convenience of longer range.

---

### **Conclusion:**

The **Auto 890-4073-20 20-gallon gas tank** is a worthwhile upgrade for **1973 1981 GM C/K trucks**, particularly if you prioritize **long-range capability, off-road use, or daily driving convenience**. The benefits of reduced refueling stops, improved emergency fuel reserves, and compatibility with aftermarket builds far outweigh the minor drawbacks, such as added weight or potential installation complexity.

If you re planning to use your truck for **long trips, towing, or heavy-duty applications**, this tank is an excellent investment. For **casual drivers or those who rarely travel far**, the upgrade may not be as necessary, but it still offers peace of mind and practical advantages.

---

### **Recommendation:**

- **Buy it if:** You need more fuel capacity for long-distance driving, off-roading, or towing, and you re willing to invest in a high-quality, long-lasting solution.

- **Skip it if:** Your truck is used primarily for short trips, you re on a tight budget, or you re unsure about installation complexity.

- **Consider alternatives:** If the Auto 890 is unavailable or too expensive, look for **OEM replacement tanks** (if compatible) or **other aftermarket brands** like **Spicer or Ford-compatible tanks** (if your truck shares similar mounting points).

For most **1973 1981 GM C/K owners**, this tank is a **smart upgrade** that enhances usability without major trade-offs. Just ensure proper installation and maintenance to maximize its lifespan.
