Straight Fuel Bowl Fitting (600 Style)

The Advanced Engine Design Straight Fuel Bowl Fitting (600 Style) is a precision brass carburetor inlet adapter engineered for Holley 4160 carburetors and compatible fuel system configurations. This straight fitting delivers reliable fuel delivery from supply line to carburetor bowl with zero obstruction or flow restriction, making it essential for both street and performance applications where fuel consistency matters.

Built from natural brass, the fitting features a 9/16-24 inch male thread on the carburetor inlet side and a 3/8 inch hose barb on the fuel line side. The straight design eliminates the pressure drops and turbulence that can occur with angled fittings, promoting steady fuel pressure and preventing vapor lock in high-heat or high-performance engine bays. The machined brass construction resists corrosion and provides years of trouble-free service in both mild and aggressive tuning scenarios.

This fitting serves rebuild, restoration, and performance carburetor work where OEM or aged fittings have cracked, stripped, or corroded. Mechanics and engine builders choose it for dry-sump conversions, fuel system upgrades, and competition builds where fuel delivery integrity is non-negotiable. The compact 3.8 x 0.75 x 4.4 inch footprint allows installation in tight engine compartments without requiring additional adapter stacks.

Compatible with Holley 4160 carburetors and similar fuel bowl inlet configurations, this fitting is a direct replacement for damaged or worn originals. It ships individually, allowing you to order exactly what your project requires without bundled extras.
