Holley Fuel Inlet Fitting -8an

The Moroso Holley Fuel Inlet Fitting -8AN is a precision carburetor inlet fitting engineered for high-performance fuel delivery in Holley carburetors. This straight-design adapter connects -8 AN male fuel lines directly to the 7/8-20 inch male carburetor port, providing a secure, leak-free transition in fuel-injected and carbureted performance builds. The black anodized aluminum construction resists corrosion while maintaining lightweight efficiency—essential for serious engine builders and hot rod enthusiasts who demand reliability under sustained high-flow conditions.

The -8 AN sizing accommodates substantial fuel flow rates required by carburetors operating in turbocharged, supercharged, and high-displacement naturally aspirated applications. The straight configuration eliminates unnecessary bends in the fuel line path, reducing pressure drop and turbulence at the inlet junction. Anodized aluminum provides dimensional stability and resists the chemical degradation common in fuel systems, while the precisely machined threads ensure repeatable engagement with standard 7/8-20 carburetor inlets found across Holley's carb lineup. This fitting arrives as a pair, allowing symmetric fuel inlet configuration on dual-carb setups or providing a spare for maintenance.

Street rods, vintage race cars, and fuel-system rebuilds rely on these fittings to bridge modern -8 AN hose standards to original Holley carburetor ports. Professional engine shops and DIY fabricators select Moroso fuel inlet fittings for their proven fit and durability across temperature swings and fuel composition variation. Whether plumbing a fresh carb installation or restoring a vintage fuel system to period-correct performance standards, this adapter delivers the precision connection serious builders expect when every component matters.
