Fuel Filter In-Line 3in 6 Micron Fiberglass 6AN

The Fuel Filter In-Line 3in 6 Micron Fiberglass 6AN from FUELAB FUEL SYSTEMS is engineered for fuel system protection in performance and street vehicles that demand reliable filtration without sacrificing flow. This compact in-line filter addresses a critical need: stopping contaminants before they reach your fuel injectors, carburetor, or fuel pump, while maintaining consistent pressure and volume under all operating conditions. Whether you're running a turbocharged engine, carbureted classic, or fuel-injected platform, this filter provides the barrier your fuel system requires to prevent wear and costly damage.

Built with a 6-micron fiberglass element, this filter captures particulates smaller than typical paper elements, offering superior contaminant removal while the microglass media resists fuel degradation and moisture absorption over extended service intervals. The 3-inch housing is constructed from black anodized aluminum, delivering corrosion resistance and a finished appearance that integrates seamlessly into engine bays and fuel system layouts. Dual 6 AN male inlet and outlet ports ensure compatibility with standard -6 hose and fitting configurations, allowing straightforward integration into both carburetor and EFI fuel systems without adapter complications.

This filter excels in applications where fuel purity directly impacts performance and reliability—from vintage hot rods and street machines to modern fuel-injected engines prone to injector clogging. Its compact 4.4 x 3.35 x 7.7-inch footprint fits tight engine compartments and custom fuel system layouts, while the aluminum construction keeps system weight minimal. Installation between your fuel pump and carburetor or fuel rail is straightforward; ensure flow direction follows arrow markings on the housing, and confirm proper 6 AN hose sizing for leak-free operation and maximum filtration efficiency.
