#6 > 7/8-20 Dual Feed Hl

The #6 > 7/8-20 Dual Feed HL carburetor inlet fitting is a precision-engineered adapter designed for fuel system integration on Holley carburetors. Built for enthusiasts and professional tuners who demand reliability in high-performance fuel delivery, this straight fitting connects AN fuel lines to Holley carb inlets with zero compromise on flow or safety. Whether you're building a custom fuel system for a street rod, race engine, or restoration project, this fitting ensures leak-free connections that withstand pressure and vibration over thousands of miles.

Manufactured by EARLS, a trusted name in fuel system components, the #6 > 7/8-20 Dual Feed HL features a 6 AN male inlet coupled to a 7/8-20 male thread outlet—the standard fuel bowl connection on most Holley carburetors. The aluminum construction is anodized in blue for corrosion resistance and easy identification within a fuel system. The straight design eliminates unnecessary bends that can restrict flow or create turbulence, while the dual-feed compatibility allows simultaneous fuel delivery to both bowls on four-barrel carburetors, maintaining balanced pressure and consistent jetting response across the engine's RPM range.

This fitting is essential for anyone upgrading fuel delivery systems or installing aftermarket fuel pumps and regulators with braided hose lines. Its compact footprint (1.45 x 1.05 x 2.95 inches) fits easily in tight engine bays, and the 0.04 lb weight adds virtually nothing to your build. Compatible with Holley 4500, 4150, and 3310-series carburetors, it works seamlessly with standard -6 AN fuel line assemblies and is recommended for systems running up to 30 PSI regulator pressure, making it suitable for most street and bracket racing applications.
