Review CHEVROLET 6.2l V8 L99 Fuel Tank Pump Oem fits CAMARO LS3 SS 2010–2012

The **Chevrolet 22790878 2010 2012 Camaro 6.2L V8 LS3 L99 Fuel Tank Pump** is a precision-engineered, direct-replacement component designed specifically for the high-performance LS3 V8 platform found in the iconic second-generation Camaro (C6) from 2010 through 2012. This fuel pump is a critical part of the vehicle s fuel delivery system, responsible for maintaining optimal pressure and flow to the engine s fuel injectors, ensuring consistent performance, throttle response, and overall drivability. Built to meet or exceed OEM specifications, this pump is engineered with a robust **12-volt electric motor** and a **high-flow impeller**, capable of delivering a steady 60 70 pounds per square inch (psi) of fuel pressure, which is essential for the LS3 s high-compression, high-output engine. The pump is housed in a **durable, corrosion-resistant housing** and features a **sealed, self-lubricating design**, reducing wear and preventing leaks over time. It is compatible with the **L99 fuel system**, which utilizes a **high-flow fuel rail and larger injectors** compared to earlier LS engines, making this pump a vital upgrade or replacement for owners seeking reliability and performance. Whether replacing a failed OEM unit or upgrading for enhanced fuel delivery, this fuel tank pump is a direct bolt-on solution that integrates seamlessly with the Camaro s fuel tank assembly, including the **integrated fuel level sender unit** for accurate gauge readings. Built to withstand the demands of aggressive driving, track use, or extended high-performance applications, this component is a testament to Chevrolet s engineering legacy while providing the durability and efficiency modern enthusiasts demand.

### **Pros and Cons of Buying a 2010 2012 Chevrolet Camaro (L99 Fuel Tank Pump, 6.2L LS3 V8) with Part Number 22790878**

#### **Pros**

1. **Performance and Power**

The 6.2L LS3 V8 engine is one of the most capable engines in the Camaro s history, producing **402 420 horsepower** (depending on the year) and **406 lb-ft of torque**. This makes it a strong choice for enthusiasts who want a high-revving, naturally aspirated V8 experience. The LS3 is known for its durability, especially when properly maintained.

2. **Strong Aftermarket Support**

The LS3 platform has a massive aftermarket presence, meaning you ll have easy access to performance parts, upgrades, and tuning solutions. Common modifications include cold air intakes, exhaust systems, ECU tuning, and suspension upgrades, which can enhance both power and handling.

3. **Classic Camaro Styling**

The **C6 generation (2010 2015)** is widely regarded as one of the most stylish Camaros ever made, with sharp lines, aggressive front fascias, and a muscular stance. The **L99** trim (available in 2010 2012) often includes unique features like **blacked-out badging, unique wheels, and a sportier interior**, making it a standout model.

4. **Potential for High Resale Value**

If well-maintained, a **low-mileage LS3 Camaro** can hold its value well, especially in the collector market. The **2010 2012 models** are still sought after by enthusiasts, and rare trims (like the **SS, ZL1, or L99**) can appreciate over time.

5. **Reliability (When Properly Maintained)**

The LS3 is a **forged-crank, aluminum-block engine** designed for durability. With **regular oil changes, cooling system maintenance, and proper fuel system care**, many LS3 engines easily exceed **200,000 miles**. However, neglect can lead to costly failures (e.g., **fuel pump, water pump, or head gasket issues**).

6. **Driving Experience**

The **LS3 s power delivery** is smooth and linear, making it enjoyable for both **daily driving and track use**. The **manual (6-speed) or automatic (6-speed) transmissions** are well-matched to the engine, and the **stiff chassis** provides a sporty ride when paired with performance tires.

7. **Fuel Tank Pump Replacement (Part #22790878) is a Common Upgrade**

The **L99 fuel tank pump** (a **Delco brand pump**) is known to fail over time, often around **50,000 100,000 miles**. Replacing it with an **aftermarket high-flow pump** (like a **Delco 22790878 or a better alternative**) can **improve fuel delivery, reduce stalling, and support performance mods**. This is a **relatively affordable fix** compared to other LS3 issues.

8. **Modularity for Future Upgrades**

The LS3 can be **easily upgraded** with **superchargers, turbochargers, or even a twin-turbo setup** (as seen in the **ZL1**). The **LS3 s architecture** allows for **forged internals, high-flow heads, and supporting mods**, making it a great platform for **future power gains**.

---

#### **Cons**

1. **Fuel Pump Reliability Issues**

The **Delco fuel pump (part #22790878)** is a **common failure point**, especially in higher-mileage examples. While replacing it is **relatively cheap ( $100 $200 for parts)**, the **original pump may fail suddenly**, leading to **stalling or no-start conditions**. Some owners report **multiple pump failures** over time, which can be frustrating.

2. **Cooling System Weaknesses**

The **LS3 s cooling system** (especially in early 2010 models) has been criticized for **underpowered water pumps, small radiators, and poor thermostat performance**. This can lead to **overheating, especially under heavy loads (e.g., track use or aggressive driving)**. Upgrades like a **high-flow water pump, larger radiator, and upgraded thermostat** are often necessary for reliability.

3. **Head Gasket and Cylinder Head Issues**

While **less common than in earlier LS engines**, some **2010 2012 LS3s** have reported **head gasket leaks or cylinder head warping**, particularly if the engine was **overheated or neglected**. Proper **cooling system maintenance** is critical to avoid these issues.

4. **Transmission Wear (Automatic Models)**

The **6-speed automatic transmission (6L80)** in the Camaro can **wear out prematurely**, especially if the **fluid was never changed or was neglected**. Some owners report **slipping, rough shifting, or complete failure** around **100,000 150,000 miles**. **Regular transmission fluid changes** are essential.

5. **Suspension and Steering Wear**

The **stock suspension (especially on higher-mileage examples)** can become **soft and worn**, leading to **poor handling and excessive body roll**. Upgrading to **coilovers, sway bars, or performance bushings** is common for enthusiasts who want a **stiffer, more responsive ride**.

6. **Interior Quality and Durability**

The **2010 2012 Camaro interiors** (especially in base trims) use **cheap plastics and soft-touch materials** that can **wear out quickly**. The **manual shifter (if equipped)** can also become **stiff or worn** over time, requiring replacement.

7. **Fuel Economy is Poor for a V8**

The **LS3 Camaro gets around 12 15 MPG in the city and 18 22 MPG on the highway**, which is **not great for a V8**. If fuel efficiency is a priority, a **turbocharged or hybrid alternative** might be more practical.

8. **Maintenance Costs Can Add Up**

While the **LS3 itself is durable**, **aftermarket upgrades (cooling, suspension, exhaust, etc.)** can become expensive. If you re not **mechanically inclined**, **labor costs** for maintenance and repairs can be high.

9. **Rust and Body Issues (Especially in Snowy Climates)**

The **C6 Camaro is prone to rust**, particularly in **wheel wells, rocker panels, and undercarriage areas**. If the car was **exposed to salt or moisture**, rust repairs can be **costly and time-consuming**.

10. **Depreciation (If Not a Collector s Model)**

While **low-mileage LS3 Camaros hold value**, most **used examples depreciate significantly** after a few years. If you re buying one **primarily for daily use**, the **resale value may not justify the purchase price** compared to newer performance cars.

---

### **Ending Conclusion**

The **2010 2012 Chevrolet Camaro (LS3, L99 trim)** is a **fantastic choice for enthusiasts** who want a **high-performance, stylish, and mod-friendly muscle car**. Its **6.2L LS3 engine** delivers **strong power, durability, and aftermarket support**, making it one of the best V8 Camaros ever made. The **L99 trim** adds **unique styling and sporty features**, while the **fuel tank pump replacement (part #22790878)** is a **common and manageable upgrade** to prevent future issues.

- **Fuel pump failures** (a **must-replace item** if buying used)

- **Cooling system limitations** (needs upgrades for track use)

- **Transmission and suspension wear** (regular maintenance is key)

- **Higher fuel costs and depreciation** (not ideal for daily commuting)

If you **inspect the car thoroughly, address the fuel pump and cooling system**, and **budget for maintenance**, a **well-maintained LS3 Camaro** can be an **excellent investment** both for **driving enjoyment and long-term appreciation**.

---
