3-1/4in Aluminum Filter #8 x 3/8in

The 3-1/4in Aluminum Filter #8 x 3/8in (model 650170) is a competition-grade fuel filter engineered for high-performance fuel systems where flow efficiency and reliability are non-negotiable. Designed as an in-line filter, this component protects fuel injectors and carburetors from particulate contamination while maintaining the fuel delivery volume critical to racing engines, street performance builds, and precision fuel management applications. The anodized aluminum construction resists corrosion and thermal stress, making it suitable for both traditional gasoline circuits and demanding motorsports environments.

This fuel filter features a stainless steel element rated at 40 microns, a filtration standard that captures contaminants without restricting fuel flow—a critical balance in competition applications where fuel pressure stability directly impacts engine performance. The housing combines aluminum for lightweight efficiency with blue and red anodized finishes that provide both aesthetic appeal and corrosion resistance. The filter accommodates an 8 AN male inlet fitting and a 3/8 inch NPT male outlet, allowing seamless integration into existing fuel systems with standard AN and NPT port configurations commonly found in fuel rails, pumps, and distribution blocks.

Buyers upgrading fuel systems on performance vehicles, fuel-injected engines, or competition builds will benefit most from this filter's ability to maintain clean fuel flow under sustained high RPM conditions. Installation requires compatible AN-to-NPT adapters if port types do not match existing plumbing, and the compact 3.8 x 2.2 x 5.65 inch footprint makes routing straightforward in tight engine bays. Regular element inspection and replacement every 10,000–15,000 miles under heavy use ensures sustained filtration performance and engine protection.
