In recent years, the use of E85 fuel has gained popularity among performance enthusiasts and eco-conscious drivers alike. However, with the benefits of using E85 come certain challenges, particularly when it comes to fuel system compatibility and performance. One of the most commonly used systems for flex fuel applications is the AEM Flex Fuel Kit. This article will explore common problems associated with the AEM Flex Fuel Kit and provide troubleshooting tips and fixes.
Understanding E85 Fuel
E85 is a fuel blend containing 85% ethanol and 15% gasoline. It is known for its higher octane rating and potential for increased horsepower. However, ethanol can be corrosive and can cause issues in fuel systems not designed for it. Understanding the properties of E85 is crucial for troubleshooting fuel system issues.
- Higher octane rating
- Potential for increased horsepower
- Corrosive properties
- Different fuel delivery requirements
Common Problems with the AEM Flex Fuel Kit
The AEM Flex Fuel Kit is designed to allow vehicles to run on varying ethanol blends. However, several common problems can arise that may affect performance and reliability.
1. Inaccurate Ethanol Content Reading
One of the primary functions of the AEM Flex Fuel Kit is to accurately measure the ethanol content in the fuel. If the readings are inaccurate, it can lead to improper tuning and performance issues.
- Check sensor connections for corrosion or damage.
- Ensure the sensor is calibrated correctly.
- Inspect the wiring for any shorts or breaks.
2. Fuel Pump Issues
The fuel pump is crucial for delivering the correct amount of fuel to the engine. E85 can be more demanding on fuel pumps, leading to premature failure.
- Check for fuel pump noise; a loud or whining sound may indicate a problem.
- Inspect the fuel filter for clogs or restrictions.
- Verify that the fuel pump is rated for E85 use.
3. Injector Compatibility
Standard fuel injectors may not be suitable for E85 due to its corrosive nature. Using the wrong injectors can lead to leaks or poor performance.
- Ensure injectors are rated for E85 compatibility.
- Inspect for leaks around the injector seals.
- Check for proper spray patterns and flow rates.
4. Fuel Line Issues
Fuel lines that are not designed for ethanol can degrade over time, leading to leaks and performance issues.
- Inspect fuel lines for cracks, swelling, or leaks.
- Replace any non-ethanol compatible lines with suitable alternatives.
- Check all connections for tightness and integrity.
Troubleshooting Steps
If you encounter issues with your AEM Flex Fuel Kit, follow these troubleshooting steps to identify and resolve the problem.
- Start by checking the ethanol content readings and sensor functionality.
- Inspect the entire fuel system for any signs of wear or damage.
- Verify that all components are compatible with E85.
- Test the vehicle under various conditions to isolate issues.
Preventative Measures
Taking preventative measures can help avoid potential issues with the AEM Flex Fuel Kit and E85 fuel systems.
- Regularly inspect fuel system components for wear and tear.
- Use E85-compatible parts and materials throughout the fuel system.
- Keep the fuel system clean and free from contaminants.
- Consider using a fuel additive designed for E85 to improve system performance.
Conclusion
While the AEM Flex Fuel Kit offers great flexibility for running on E85, it is essential to be aware of the common problems and troubleshooting steps outlined in this article. By understanding the potential issues and taking preventative measures, you can ensure a smoother experience with your flex fuel system and enjoy the benefits of E85 fuel.
