Fuel Filters

About

A clogged or failing fuel filter is one of the fastest ways to choke off horsepower, foul your fuel injectors, or burn out an expensive fuel pump. Whether you're running a daily driver, an LS swap, or a full race build, Evil Energy's fuel filters are built from aircraft-grade aluminum and washable stainless steel mesh to keep dirt, rust, and sediment out of your fuel system — without the recurring cost of disposable OEM cartridges. Inline, AN & High-Flow Fuel Filters for Every Fuel System Not every engine filters fuel the same way. Our universal inline fuel filter bolts into almost any setup with swappable 6AN, 8AN, and 10AN adapters or barb fittings (5/16", 3/8", 1/2"), making it the easiest starting point for carbureted and classic-car builds. For braided-line performance builds, our AN fuel filter models thread straight into 6AN, 8AN, or 10AN lines for EFI conversions, LS swaps, and turbo setups. For high-horsepower and boosted applications that need maximum fuel volume with minimal pressure drop, our high flow fuel filter housings offer more filtration surface area than a typical OEM canister. And because every element is E85-, gas-, and diesel-compatible, the same performance fuel filter platform works whether you're running pump gas or flex fuel. How to Choose the Right Micron Rating Micron rating should match where the filter sits in your fuel system, not just your budget. As a general rule: Micron Rating Best For Typical Placement 100 Micron Pump protection, coarse pre-filtration Before the fuel pump (pre-filter) 30–40 Micron Carbureted engines After the pump, before the carburetor 10 Micron EFI fuel filter applications, fuel injectors After the pump, before the fuel rail Because Evil Energy filters use a removable, washable stainless steel element instead of a sealed paper cartridge, you're not stuck replacing the entire housing every 30,000–60,000 miles — just clean or swap the element and keep running.
