Carb Fitting w/washer 7/8-20 to -6 Male Blue

The Carb Fitting w/washer 7/8-20 to -6 Male Blue is a precision carburetor inlet adapter designed for fuel system installations on carbureted engines, particularly Holley carburetors. This straight fitting serves as the critical bridge between fuel supply lines and carburetor inlet ports, making it essential for any serious engine builder or restoration enthusiast working with traditional carbureted powerplants. Whether you're upgrading a classic street rod, restoring a vintage muscle car, or tuning a high-performance competition engine, this adapter ensures proper fuel delivery with a secure, leak-free connection.

Constructed from aluminum with blue anodized finish, this carb fitting combines durability with corrosion resistance—a critical consideration in engine bays subject to heat cycling and moisture exposure. The fitting converts a 7/8-20 male thread (the standard Holley carburetor inlet port) to a -6 AN male port, which accommodates standard braided fuel lines and fittings used throughout modern fuel system configurations. The included washer ensures a proper seal at the carburetor, preventing fuel seepage and maintaining consistent fuel pressure delivery to the engine. Straight configuration allows for direct, unobstructed fuel flow without flow-restricting bends, maximizing carburetor responsiveness during acceleration and load changes.

Mechanics and engine builders rely on this fitting when converting older fuel systems to standardized AN plumbing, upgrading fuel delivery on vintage Holley carbs, or troubleshooting inconsistent fueling on restored engines. The blue anodized finish provides clear visual identification in engine compartments and integrates seamlessly with modern fuel system aesthetics. Installation is straightforward: thread directly into the carburetor inlet port with the included washer, then connect your -6 AN fuel line using appropriate hose and fittings. This adapter is compatible with all Holley carburetor models featuring standard 7/8-20 inlet threads, making it a universal solution for fuel system modernization and repair.
