The compatibility of E85 fuel with metal components in fuel systems depends on the age of the system. Older vehicles, particularly those manufactured before 1994, may have fuel systems that are not resistant to ethanol. In such cases, E85 fuel can cause corrosion and damage to fuel lines, fuel pumps, and other components. However, for vehicles with newer fuel systems or those installed with ethanol-safe kits, E85 fuel is generally considered safe and compatible.
It is worth noting that fuel cell manufacturers often include foam in the fuel cells for crash protection. While E85 fuel may not cause immediate issues with the foam, it can break down over time, regardless of the type of fuel used. Therefore, it is recommended to consult the manufacturer for specific guidance on fuel cell foam compatibility and safety considerations.
Precautions and considerations:
To ensure compatibility and prevent corrosion, it is important to use Viton seals, which are impervious to degradation caused by alcohol exposure. Additionally, fuel lines, pumps, regulators, rails, tank seals, and the fuel tank itself should be rated for use with E85 fuel. Regular maintenance and monitoring for leaks or corrosion are also crucial to mitigate any potential issues.
In conclusion, while E85 fuel may react with certain metals, causing corrosion, it can be safely used with modern fuel systems that are designed to be ethanol-resistant. Proper precautions, such as using compatible parts and maintaining the fuel system, can help prevent issues and ensure the safe and efficient use of E85 fuel.
