Fuel Filter End Cap -12

The Fuel Filter End Cap -12 AN Male to 1-13/16-20 in Male O-Ring by Allstar Performance is a precision hydraulic adapter engineered for high-performance fuel filtration systems in racing and performance automotive applications. This end cap serves as a critical connection point in in-line fuel filter assemblies, directing pressurized fuel flow while maintaining system integrity under demanding conditions. Designed for builders and technicians who require reliable, leak-free fuel system components, this adapter bridges two different connection standards with the same dependable engineering found across professional racing platforms.

Manufactured from lightweight aluminum and finished in black anodize, the Fuel Filter End Cap -12 provides corrosion resistance and durability in fuel-saturated environments while minimizing parasitic weight. The -12 AN male thread (1.75-inch SAE standard) couples with the 1-13/16-20 inch male O-ring port, allowing seamless integration between Allstar in-line filter housings and remote-mounted filtration stages. The anodized finish protects against oxidation and fuel degradation, critical for maintaining system cleanliness and preventing contamination that can damage fuel injectors and carburetors. At just 0.18 lbs, this component adds negligible mass while delivering full flow capacity without pressure drops.

This end cap is ideal for race car builders, engine shops, and performance enthusiasts installing Allstar Performance fuel filter systems in EFI conversions, carbureted hot rods, and circle-track competition vehicles. Installation requires compatible -12 AN hose fittings on the inlet side and a mating 1-13/16-20 female port on the filter housing outlet. Verify your system's thread specifications before ordering to ensure proper fitment; this adapter is sold individually and pairs with standard Allstar filter cartridges and housings. Compact dimensions ensure fitration in tight engine bay installations common in vintage and modern performance builds.
