The EVIL ENERGY inline fuel filter is a high-flow, precision-engineered fuel filter designed for a wide range of modern and performance-based fuel systems.

Built for durability and versatility, the EVIL ENERGY fuel filter is compatible with gasoline, E85, ethanol blends, and race fuels. You can choose between 10 micron and 100 micron fuel filter elements, depending on whether you're filtering before or after the pump.
An inline fuel filter is one of the most important components for protecting your engine from dirt, rust, and fuel-borne debris.
