Fuel Inlet Fitting 6an Ano-Tuff w/Pro-Lite Hose

The Holley Fuel Inlet Fitting 6AN Ano-Tuff w/Pro-Lite Hose is engineered for carbureted fuel systems requiring reliable, high-flow fuel delivery to Holley 4150-style carburetors. This fitting serves as the critical junction point between your fuel line and carburetor inlet, designed for builders who demand durability and leak-free operation in street, strip, and performance applications. Whether you're upgrading a classic muscle car or tuning a dedicated drag racer, this component handles the pressure and vibration cycles that come with aggressive fuel delivery demand.

Constructed from aluminum with black anodized finish, the Ano-Tuff fitting resists corrosion and oxidation from fuel exposure and engine bay heat cycles. The fitting features a 6 AN male inlet connection paired with dual 6 AN female outlets, allowing you to split fuel flow or accommodate dual-feed carburetors with a single fuel line source. The included Pro-Lite braided nylon hose provides flexibility without kinking while maintaining structural integrity under sustained pressure—critical when dealing with mechanical or electric fuel pumps pushing consistent volume at elevated PSI. This hose assembly eliminates the need for separate crimping or custom fitting fabrication.

Mechanics and engine builders favor this fitting for Holley 4150 carburetors—the industry standard for naturally aspirated and supercharged applications. Installation requires only AN-compatible hose connections and standard wrenches, making it accessible for both professional shops and experienced DIY tuners. The compact 6.1-inch length (0.6 lbs) integrates cleanly into tight engine bay layouts without interference with intake manifolds or valve covers. Verify your fuel pump outlet size and carburetor inlet specifications match 6 AN before purchase to ensure proper fitment and optimal system flow rates for your build.
