Carb. Adapter

The EARLS Carb. Adapter (model 991956ERL) is a precision-engineered fuel system fitting designed for high-performance carburetor and fuel pressure applications. This straight adapter bridges 6 AN male connections to 18 mm x 1.50 male O-ring ports, making it essential for custom fuel delivery systems, race vehicles, and engine swaps where OEM fuel lines cannot accommodate modern aftermarket carburetors or fuel management components. Whether you're building a fuel system for a classic engine conversion or upgrading carburetor compatibility on a competition platform, this adapter ensures leak-free, secure connections under pressure.

Constructed from aluminum and finished in blue anodized coating, this carburetor adapter resists corrosion while maintaining a lightweight profile ideal for performance builds. The blue anodize protects against oxidation in high-heat engine bay environments and provides a professional appearance in visible fuel system installations. The 6 AN male to 18 mm x 1.50 male O-ring configuration ensures compatibility with standard AN fuel line hose and adapters on one end while accepting metric O-ring face seal fittings on the other, eliminating the need for multiple adapter chains and reducing potential leak points in your fuel system architecture.

This adapter is ideal for fuel system integrators, engine builders, and performance enthusiasts working with hybrid fuel delivery systems that combine modern AN-standard components with metric-threaded carburetors or fuel injection units. Its compact dimensions (1.2 x 1.05 x 2.85 inches) allow installation in confined engine compartments without requiring extensive rerouting of fuel lines. Ensure your fuel delivery system pressure rating matches the adapter's rated capacity, and use with compatible O-ring seals for optimal performance and reliability under sustained operation.
