The Filter End Cap Inlet 16 AN 400 Series by Peterson Fluid is a precision-engineered fuel filter component designed for high-performance and racing fuel systems. This aluminum inlet cap serves as a critical interface in fuel filtration assemblies, directing incoming fuel through the filter element while maintaining structural integrity under pressure. Built for serious motorsports applications, off-road vehicles, and custom fuel system builds, this end cap is essential for anyone running Peterson's 400 series fuel filter housings who demands reliability and professional-grade construction.

Manufactured from aluminum and finished in vibrant red anodizing, the Filter End Cap Inlet 16 AN 400 Series provides corrosion resistance and visual identification within fuel system layouts. The 16 AN male inlet port utilizes industry-standard AN (Army-Navy) sizing, ensuring compatibility with braided fuel hoses and fittings throughout the motorsports community. Anodized finishes on aluminum components offer superior protection against fuel degradation and environmental exposure, while the compact design (3.6 x 2.55 x 4.5 inches) integrates seamlessly into tight engine bays. At just 0.24 lbs, this lightweight component adds minimal mass to your fuel system without sacrificing durability or pressure ratings.

This inlet cap is ideal for fabricators, engine builders, and enthusiasts upgrading fuel delivery on naturally aspirated or forced-induction platforms. Peterson 400 series filters see frequent use in circle track racing, drag racing, and street performance applications where fuel purity and consistent flow are non-negotiable. Direct replacement or upgrade installations benefit from the standardized 16 AN inlet, eliminating fitment guesswork. Verify your existing filter housing model matches the 400 series specification before ordering to ensure proper seating and seal integrity.
