#6AN Stainless Fuel Filter

The #6AN Stainless Fuel Filter from KLUHSMAN RACING PRODUCTS is a vital component for any serious fuel system modification or high-performance engine build. Designed for racers, street performance enthusiasts, and mechanics upgrading fuel delivery systems, this filter sits between your fuel pump and engine fuel rail to remove particulates and contamination that can damage fuel injectors or restrict flow. Whether you're running a carbureted classic, a turbocharged street car, or a dedicated race engine, a quality fuel filter rated for your AN hose size is non-negotiable for reliability and longevity.

Stainless steel construction provides superior corrosion resistance compared to aluminum or plastic-bodied filters, especially in salt-air environments or long-term storage scenarios common in collector and race vehicles. The #6AN port size accepts standard -6 AN hose fittings, allowing seamless integration into modern braided or PTFE fuel lines that are common in engine swaps and fuel system upgrades. The compact cylindrical design (2.5 x 2.2 x 12.7 inches) fits tight engine bay layouts where space is premium, and its 0.78 lb weight contributes minimal parasitic load. KLUHSMAN RACING PRODUCTS engineers their filters for high flow rates while maintaining fine filtration, balancing pressure drop against contamination removal—critical when feeding high-horsepower fuel injectors that demand clean fuel.

This filter is ideal for turbocharged and supercharged applications, fuel-injected retrofits, and any fuel system running boost or aggressive tuning where fuel quality directly impacts combustion stability and component life. Installation requires AN-compatible hose barbs or fittings (sold separately) and a secure mounting location away from excessive heat sources; many builders use stainless steel brackets or magnetic clamps to secure the filter body. Mechanics and tuners routinely specify this filter for customer builds because its stainless body eliminates concerns about corrosion-induced failures mid-season or during off-season storage, and the established KLUHSMAN RACING PRODUCTS reputation ensures consistent performance across builds.
