Buying a replacement fuel tank cap for a 1951-1959 GMC 250 gas storage air system (specifically a Motorad C699 model from 2015-2018) can be a practical solution if your original cap is damaged or incompatible. Below are the key pros and cons of this approach, followed by a conclusion and recommendation.

---

1. **Compatibility with Modern Standards** The Motorad C699 cap is designed for modern fuel systems, which may include better sealing mechanisms, corrosion-resistant materials, and potentially EVAP (Evaporative Emission Control) compatibility. Older GMC models may lack these features, making a newer cap a safer upgrade.

2. **Durability and Longevity** Motorad parts are generally built to withstand wear and tear better than aftermarket or generic replacements. The materials used in their caps are often more resistant to cracking, rust, and fuel degradation over time.

3. **Ease of Installation** The Motorad cap is likely designed with straightforward installation in mind, featuring clear mounting points and a secure fit. This can reduce the risk of improper sealing, which could lead to fuel leaks or vapor loss.

4. **Fuel Vapor Control** If your GMC s original cap lacks an EVAP system or proper sealing, the Motorad cap may include features to reduce fuel vapor emissions, improving fuel efficiency and reducing environmental impact.

5. **Warranty and Reliability** Motorad is a reputable brand with a track record of producing reliable automotive parts. Purchasing from them may come with a warranty, offering peace of mind in case of defects.

6. **Aesthetic and Functional Consistency** If you re restoring or maintaining the appearance of your GMC, a Motorad cap may blend better with modern or aftermarket fuel systems while still functioning correctly.

---

1. **Potential Size or Fit Issues** The Motorad C699 cap is designed for a specific fuel tank configuration (likely for modern vehicles). A 1951-1959 GMC 250 may have a different tank shape, venting system, or mounting hardware. Without exact measurements or a clear adapter solution, there s a risk the cap won t fit properly, leading to leaks or improper sealing.

2. **Incompatibility with Original Vapor System** Older GMCs may rely on a simple venting system rather than an EVAP system. A modern cap with EVAP features could disrupt the original airflow, potentially causing fuel starvation or other engine performance issues if not properly integrated.

3. **Cost Consideration** Motorad parts are often priced higher than generic or aftermarket alternatives. If the original cap is still functional or easily replaceable with a vintage part, the cost may not justify the upgrade.

4. **Lack of Vintage-Specific Features** Older vehicles may require specific venting or pressure-release mechanisms that a modern cap doesn t accommodate. Without modifications to the tank or fuel system, the cap might not perform as intended.

5. **Potential for Overkill** If your GMC s fuel system is in good condition and the original cap is merely worn or rusted, replacing it with a modern cap could be unnecessary. A simple replacement of the original cap (if available) or a vintage-compatible aftermarket part might suffice.

6. **Installation Challenges** If the Motorad cap requires additional modifications (e.g., cutting or adapting the tank s venting system), the installation process could be more complex than anticipated, requiring mechanical expertise.

---

Buying a Motorad C699 fuel tank cap for a 1951-1959 GMC 250 is a viable option if you prioritize modern durability, EVAP compatibility, and ease of installation. However, the decision hinges on whether the cap will physically and functionally integrate with your vehicle s original fuel system. If your GMC s tank and venting setup are compatible with the Motorad cap (or can be easily adapted), this upgrade could be a sound choice. Conversely, if the original cap is still serviceable or a vintage replacement is readily available, the added cost and potential fitment issues may not be worth it.

---

1. **Verify Compatibility** Measure the fuel tank s vent opening and compare it to the Motorad cap s dimensions. Check if the cap s threading or mounting style matches your GMC s tank. If in doubt, consult a mechanic or a vintage vehicle restoration specialist.

2. **Assess Fuel System Needs** Determine whether your GMC s fuel system requires EVAP features or if a simple vented cap will suffice. If the original system is functional, a vintage or aftermarket cap designed for your GMC s era may be a better fit.

3. **Consider Alternative Sources** Explore aftermarket vendors specializing in vintage GMC parts. Some may offer caps designed specifically for 1950s models that balance compatibility, cost, and performance.

4. **Test Fit Before Finalizing** If possible, borrow or purchase the cap to test-fit it on your tank. This will confirm whether modifications (e.g., cutting a new vent hole) are needed.

5. **Prioritize Function Over Form** If your primary concern is fuel leaks or a worn seal, focus on a cap that ensures a tight, vapor-tight fit. If aesthetics or modern features are your main goal, weigh the practicality against the potential drawbacks.

**Final Verdict:** Proceed with the Motorad cap only if you re confident in its compatibility with your GMC s fuel system and are willing to address any necessary modifications. Otherwise, opt for a vintage-compatible or aftermarket replacement that aligns better with your vehicle s original specifications.
