6an Inline Fuel Filter 40 Micron 2in OD Black

The 6AN Inline Fuel Filter 40 Micron 2in OD Black from Aeromotive is a critical component for any fuel system requiring reliable contamination control and flow consistency. Whether you're building a high-performance street engine, upgrading a carbureted classic, or tuning a fuel-injected platform, this inline filter protects injectors, carburetors, and fuel pumps from particulate damage that accumulates in tanks and fuel lines. Mechanics and engine builders trust Aeromotive's precision engineering to maintain system integrity under demanding conditions.

This 40-micron filter element removes particles down to 40 microns, the threshold where fuel injector spray patterns degrade and carburetor needles stick—making it ideal for carbureted and naturally aspirated engines as well as modest boost applications. The compact 2-inch outer diameter (OD) design fits tight engine bays, bracket mounts, and underseat installations without requiring extensive chassis modification. AN-6 (JIC -6) hose connections provide leak-free, vibration-resistant attachment to braided stainless or rubber fuel line, and the black powder-coated aluminum body resists corrosion while maintaining weight savings critical to performance builds.

Street rods, resto-mods, vintage race cars, and fuel-injected swap projects benefit most from this filter's balance of filtration and flow. Installation requires basic hose routing skills and attention to fuel pressure specifications—mount the filter between the tank and pump for pre-pump protection, or post-pump for final injection system defense. The 0.67 lb weight and compact 3.2 x 2.2 x 8.3 inch footprint make placement flexible across engine configurations, from under-hood rack systems to rear-mounted fuel cell setups.
