Review CHRYSLER Plymouth Oem Fair Of Fuel Tank Straps fits PROWLER 1997–2002

The **Chrysler 4786639 Plymouth Prowler (1997 2002) Fair Fuel Tank Straps** are a critical yet often overlooked component designed to ensure the structural integrity and proper alignment of the fuel tank assembly in one of the most iconic and customizable sports cars of the late 1990s and early 2000s. These high-quality, heavy-duty straps are engineered to securely fasten the fuel tank to the chassis, preventing excessive movement, vibration, or shifting especially during aggressive driving, off-road excursions, or after modifications that alter the vehicle s weight distribution or suspension geometry. Crafted from durable, corrosion-resistant materials, these straps are built to withstand the rigors of daily use while maintaining a tight, consistent seal around the tank s mounting points. Whether you re restoring a classic Prowler to its original glory, preparing it for track days, or simply ensuring long-term reliability, these straps provide the necessary support to keep the fuel system stable, reducing the risk of leaks, damage to fuel lines, or even catastrophic failure under extreme conditions. Their precise fitment and robust construction make them an essential upgrade for enthusiasts who demand both performance and peace of mind, bridging the gap between stock reliability and high-performance modifications.

### **Pros and Cons of Buying Chrysler 4786639 Plymouth Prowler (1997 2002) Fuel Tank Straps**

#### **Pros:**

1. **Reliability for a Classic Muscle Car** The Plymouth Prowler was designed as a modern take on the classic muscle car, and while it has quirks, its mechanical components (including the fuel system) are generally robust for its era. The fuel tank straps (part #4786639) are a common wear item, but they are straightforward to replace, preventing leaks that could damage the fuel system or pose a fire hazard.

2. **Easy to Source and Install** This part is widely available from aftermarket suppliers, Chrysler dealerships, and online retailers. It is a bolt-on replacement with minimal tools required, making it a DIY-friendly fix. Many Prowler owners report that replacing these straps is a simple weekend project.

3. **Prevents Fuel Leaks and Contamination** The original fuel tank straps degrade over time due to exposure to heat, vibration, and fuel vapors. Replacing them ensures the tank remains securely fastened, reducing the risk of fuel leaks, which could contaminate the fuel system or create a safety hazard.

4. **Cost-Effective Fix** Compared to other potential fuel system issues (e.g., a cracked fuel tank or failed fuel pump), replacing the straps is relatively inexpensive. The part itself is affordable, and labor costs are minimal if done at home.

5. **Maintains Resale Value for Enthusiasts** While the Prowler is not a common daily driver, its cult following means that well-maintained examples (especially with original or restored components) can hold value among collectors. Keeping up with routine maintenance like fuel tank straps ensures the car remains in good condition for potential buyers.

6. **Prevents Long-Term Damage** If the straps fail completely, the fuel tank could shift, leading to damage to the tank itself, fuel lines, or surrounding components. Replacing them proactively avoids costly repairs down the line.

#### **Cons:**

1. **Potential for Counterfeit or Low-Quality Parts** Some aftermarket suppliers sell knockoff or poorly manufactured fuel tank straps that may not last as long as OEM or high-quality replacements. Buyers should purchase from reputable sellers (e.g., RockAuto, Summit Racing, or direct from Chrysler) to avoid this issue.

2. **Rust and Corrosion Risks** The Prowler s fuel tank and surrounding components are susceptible to rust, especially if the car has been exposed to moisture or driven in harsh conditions. Even with new straps, rust in the tank or mounting points could still be a concern, requiring additional inspections.

3. **Time-Consuming Installation for Inexperienced DIYers** While the straps themselves are easy to replace, accessing the fuel tank may require removing the rear seats, floor mats, or parts of the interior trim. First-time installers might find the process more involved than expected, especially if they lack experience with fuel system work.

4. **Limited Longevity of the Fix** Fuel tank straps are not designed to last indefinitely. While replacing them extends their lifespan, they will eventually degrade again, requiring future replacements. This is a recurring maintenance cost for Prowler owners.

5. **Potential for Overlooking Other Issues** Some owners focus solely on the fuel tank straps and neglect other critical maintenance items (e.g., fuel pump, fuel lines, or electrical components). A thorough inspection of the entire fuel system is recommended to avoid overlooking other problems.

6. **Environmental and Safety Concerns** Fuel systems involve flammable liquids, so any work around the tank requires caution. Improper handling of fuel or tools near the tank could pose a safety risk. Owners should follow proper fuel system safety protocols (e.g., relieving fuel pressure before working).

---

### **Conclusion:**

The Chrysler 4786639 Plymouth Prowler fuel tank straps are a practical and necessary part to maintain for any owner of this vehicle. The pros such as ease of replacement, cost-effectiveness, and prevention of leaks outweigh the cons, which are largely manageable with proper sourcing, installation care, and awareness of the car s maintenance needs. This part is a smart investment to avoid more serious (and expensive) fuel system failures.

For most Prowler owners, replacing these straps is a routine and worthwhile task that extends the life of the vehicle and ensures safe operation. However, it should be part of a broader maintenance plan that includes checking for rust, inspecting fuel lines, and addressing any other signs of wear in the fuel system.

---

### **Recommendation:**

- **Buy the part from a trusted supplier** (e.g., RockAuto, Summit Racing, or an authorized Chrysler parts dealer) to ensure quality and compatibility.

- **Follow proper fuel system safety procedures** when replacing the straps, including relieving fuel pressure and working in a well-ventilated area.

- **Inspect the fuel tank and surrounding components** for rust or damage while the straps are removed. Address any issues immediately to prevent future problems.

- **Consider upgrading to high-quality aftermarket straps** if available, as they may offer better durability than OEM parts.

- **Keep a record of maintenance** to track when the straps were last replaced and plan for future replacements as needed.

- **If unsure about installation**, consult a professional mechanic familiar with Prowler models to ensure the job is done correctly.

For the average Prowler owner, replacing these straps is a straightforward and beneficial maintenance task that should not be overlooked. It balances practicality, cost, and safety, making it a recommended part to keep in stock or replace as part of regular upkeep.
