In Line Fuel Filter -6AN Ends Black

The In Line Fuel Filter -6AN Ends Black by Billet Specialties is a critical component for any serious engine builder, street machine enthusiast, or performance mechanic looking to protect fuel system integrity. Whether you're running a carbureted classic, EFI swap, or modern high-flow fuel system, this inline filter sits between your fuel pump and carburetor or injector rails to trap contaminants before they reach sensitive engine components. A quality fuel filter isn't optional—it's insurance against injector clogs, carburetor varnish buildup, and premature fuel pump wear that can derail a build or leave you stranded.

This Billet Specialties unit features a 40-micron stainless steel filter element—fine enough to catch rust, dirt, and debris while maintaining adequate flow for both stock and modified fuel systems. The all-aluminum body is anodized black for corrosion resistance and a clean engine bay aesthetic that complements custom fuel lines and show-quality builds. Dual 6AN male ports accept standard -6 hose or hard-line connections, giving you flexibility in fuel system routing whether you're installing it under the hood, in a custom engine bay, or as part of a fuel cell setup. The compact 5.25 x 1.55 x 6-inch footprint and lightweight 0.25 lbs design make it easy to mount in tight spaces without adding bulk or weight to your build.

This filter is ideal for vintage muscle car restorations, street rod fuel system upgrades, and performance engine swaps where OEM filter housings don't fit your new layout. Professional mechanics and DIY builders alike rely on 40-micron filtration to extend the life of expensive fuel injectors, regulators, and carburetors—especially critical when running ethanol blends or reconditioned fuel system components. The 6AN connection standard pairs seamlessly with AN-style braided hose, making integration straightforward for any fuel system upgrade project. Install it close to the fuel pump outlet for maximum protection, and expect hassle-free performance across naturally aspirated and forced-induction applications.
