Carb Adapter Fitting #8 x 7/8-20

The Carb Adapter Fitting #8 x 7/8-20 from FRAGOLA is a precision carburetor inlet fitting engineered for custom fuel system installations in high-performance street rods, vintage hot rods, and race vehicles. This adapter bridges the critical connection between modern fuel lines and traditional carbureted engine platforms, making it essential for builders transitioning to aftermarket fuel delivery systems or upgrading carburetor fuel inlets. Its straight design eliminates flow restrictions while the O-ring seal ensures leak-free operation under varying pressure conditions.

Constructed from lightweight aluminum with blue anodized finish, this fitting resists corrosion and integrates seamlessly into custom engine bays while maintaining a professional appearance. The 8 AN male connection accepts standard braided stainless steel fuel lines, while the 7/8-20 male O-ring seal threads directly into carburetor inlet ports, eliminating the need for additional adapters or barbed fittings that can weigh down fuel system plumbing. FRAGOLA's precision manufacturing ensures concentricity and thread concentricity, critical factors for maintaining fuel line angles and preventing vibration-induced wear or leakage at high RPM.

Mechanics and engine builders favor this carb adapter fitting for Holley, Edelbrock, and other aftermarket carburetors featuring 7/8-20 inlet ports. It's ideal for fuel-injected engine swaps into carbureted platforms, custom fuel system upgrades, and competition builds where clean plumbing and reliable sealing are non-negotiable. The compact footprint (measuring 1.65 x 1.25 x 4.1 inches) allows flexible routing in tight engine compartments, while the minimal weight of 0.03 lbs keeps fuel system mass low for weight-conscious builds.
