The #8 Dual Feed Holley Black carburetor inlet fitting is a precision-engineered fuel delivery component designed for serious engine builders and performance enthusiasts running Holley carburetor systems. This straight adapter bridges the gap between your fuel line and carburetor inlet, converting an 8 AN male thread connection to a 7/8-20 inch male port with exacting tolerances. Whether you're tuning a classic muscle car, street rod, or modern fuel-injected engine conversion, reliable fuel delivery starts with a robust, properly-sized inlet fitting that won't leak or restrict flow.
Machined from lightweight aluminum and finished in black anodize, the #8 Dual Feed Holley Black fitting resists corrosion while maintaining a clean, professional appearance under the hood. The straight configuration minimizes turbulence and pressure drop, critical for consistent fuel atomization and carburetor performance across the RPM range. Black anodized aluminum provides superior durability compared to bare aluminum or plated finishes, especially in high-vibration engine compartments where fuel fittings endure constant stress and temperature cycling. The dual-feed designation indicates this fitting integrates into dual-circuit fuel delivery systems common in high-performance applications requiring redundant or staged fuel supply.
Technicians and engine builders choose this fitting when upgrading carburetor fuel systems on classic vehicles, race engines, and high-displacement street applications. The 8 AN to 7/8-20 conversion accommodates both modern braided fuel lines (8 AN spec) and original Holley carburetor inlet ports, making it ideal for retrofitting newer fuel delivery technology onto vintage or stock carburetors. Compact dimensions (3.55 x 1.8 x 4.65 inches) ensure hassle-free installation in tight engine bay layouts, and the lightweight 0.11 lb construction adds negligible mass. Proper installation with thread sealant and correct torque specifications ensures leak-free operation and years of dependable fuel delivery.
