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. Whether you're building an LS swap fuel system, tuning a turbocharged EFI setup, or upgrading your car fuel filter, this filter delivers clean, uninterrupted fuel flow and consistent pressure.

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.

Common symptoms include engine hesitation, reduced power, hard starts, and even stalling. In EFI systems, a clogged filter can reduce fuel pressure and cause injector misfires.

Can a fuel filter cause a car not to start?
Yes. A completely clogged fuel filter can restrict fuel flow and prevent your engine from starting.

How often should a fuel filter be replaced?
Replacement depends on your fuel type and system. Most filters should be inspected every 12,000 to 15,000 miles. Our inline fuel filter can be cleaned and reused.

Can I clean my EVIL ENERGY inline fuel filter?
