Review PLYMOUTH MOPAR Gas Gauge Nos Factory Oem Fuel fits 1938

The **Plymouth Mopar 678346 1938 Gas Gauge (No-Signal Fuel Level Indicator)** is a meticulously crafted, vintage automotive component designed to replicate the original functionality and aesthetic of the classic 1938 Plymouth fuel gauge assembly. This high-quality, no-signal gauge is a sought-after restoration piece for enthusiasts aiming to preserve the authentic look and feel of early Mopar-era vehicles, particularly those from the late 1930s. Crafted with precision, the gauge features a sleek, chrome-plated housing that exudes the polished elegance of the era, complete with a rounded, retro dial face that seamlessly integrates with the vintage dashboard styling of the time.

This gauge is not merely a functional replacement but also a nostalgic nod to automotive history, ideal for collectors, restorers, and drivers who appreciate the artistry of early 20th-century automotive design. Whether installed in a meticulously restored 1938 Plymouth or a modern classic with a retro-inspired interior, this gauge adds a touch of authenticity and charm, bridging the gap between past and present with timeless precision.

### **Pros and Cons of Buying a 1938 Plymouth Mopar 678346 Gas Gauge (NOS Fuel)**

#### **Pros**

1. **Historical Significance and Rarity**

The 1938 Plymouth gas gauge (part number 678346) is a classic automotive component from an early Mopar vehicle. Original, No-Stock (NOS) parts from this era are highly sought after by collectors and restorers, making this a valuable piece for enthusiasts.

2. **Functional and Aesthetic Value**

The gauge is likely part of a vintage instrument cluster, which adds to the authenticity of a restored vehicle. Original gauges enhance the authenticity of a classic car, making it more desirable to purists.

3. **Potential for Investment**

NOS parts, especially from the 1930s, tend to appreciate over time. If preserved properly, this gauge could be worth more in the future, particularly if demand for vintage automotive parts continues to grow.

4. **Compatibility with Restoration Projects**

If you are restoring a 1938 Plymouth or another Mopar vehicle from the same era, this gauge would be an ideal match. It ensures historical accuracy and avoids the need for aftermarket replacements.

5. **Craftsmanship and Design**

#### **Cons**

1. **Age and Wear**

The gauge may show signs of aging, such as rust, cracked glass, or worn wiring. If it is not in perfect condition, restoration or replacement of internal components may be required, adding to the cost.

2. **Functionality Issues**

Vintage gauges can be finicky. The mechanism inside may not work properly due to dried-out lubricants, corroded contacts, or failing springs. Testing and possibly rebuilding the gauge could be necessary.

3. **Limited Availability of Replacement Parts**

Finding replacement parts for a 1938 gauge can be difficult. If the gauge fails, sourcing a compatible replacement may require searching through specialty suppliers, eBay, or restoration shops, which could be time-consuming and expensive.

4. **Cost of Restoration**

If the gauge is not fully functional or is damaged, restoring it to working order may require professional help. Labor costs for vintage automotive restoration can be high, and the time investment should be considered.

5. **Market Saturation and Value Fluctuations**

While NOS parts can appreciate, the market for vintage automotive gauges is niche. There may be oversaturation of similar parts, leading to lower resale value than anticipated. Prices can also fluctuate based on collector demand.

6. **Potential for Counterfeit or Rebuilt Items**

Buying NOS parts online or from less reputable sellers carries a risk of receiving a rebuilt or counterfeit item. Ensuring authenticity may require verification from a trusted source or expert.

---

### **Conclusion**

Buying a 1938 Plymouth Mopar 678346 gas gauge (NOS) is a decision that hinges on whether you prioritize historical authenticity, investment potential, or the joy of restoring a classic piece. If you are a collector or restorer with the patience and resources to evaluate and repair the gauge, it can be a rewarding purchase. However, if you are not prepared for potential restoration challenges or the uncertainty of resale value, the risks may outweigh the benefits.

---

### **Recommendation**

If you are certain about the gauge s authenticity and condition, and you have the skills or access to restoration expertise, purchasing this NOS part could be a worthwhile investment for a vintage car project. Here s how to proceed:

1. **Verify Condition and Functionality**

Inspect the gauge closely for signs of damage, rust, or mechanical issues. If possible, test it in a known-good circuit to ensure it operates correctly. If it is non-functional, factor in the cost of restoration.

2. **Research Market Value**

Check recent sales of similar gauges to gauge its current market value. Websites like eBay Sold Listings, classic car forums, or specialty auction sites can provide benchmarks.

3. **Consider Professional Restoration**

If the gauge requires rebuilding, consult a vintage automotive specialist to assess the scope of work and associated costs. This will help you determine whether the restoration is feasible within your budget.

4. **Buy from a Trusted Source**

Purchase from a reputable seller with a history of authentic NOS parts. Request documentation or verification of the gauge s origin if possible.

5. **Balance Passion with Practicality**

If you are buying primarily for a restoration project, ensure the gauge fits within your overall budget and timeline. If you are investing for resale, be realistic about the market demand and potential appreciation.

**Final Verdict:** This gauge is ideal for dedicated collectors or restorers who value authenticity and are prepared for the challenges of working with vintage automotive parts. For casual buyers or those without restoration experience, the risks may not be justified. Proceed with careful consideration of the gauge s condition, market value, and your own capabilities.
