P/C #6 to 9/16-24 Holley Carb Fitting

The Russell P/C #6 to 9/16-24 Holley Carb Fitting is a precision hose adapter designed for fuel system connections on carbureted performance engines. This banjo-style fitting bridges the gap between modern -6 AN hose plumbing and classic Holley carburetor inlet ports, making it essential for builders modernizing fuel delivery on vintage or modified engines. Whether you're upgrading from antiquated rubber fuel lines to reliable braided stainless steel or integrating electronic fuel pumps into a classic fuel system, this adapter ensures leak-free, high-pressure connections where OEM fittings fall short.

Machined from aluminum and anodized in black and silver for corrosion resistance, the Russell fitting features a straight banjo design that minimizes turbulence and fuel foaming under load. The 6 AN hose connection uses industry-standard JIC flare threads, while the 9/16-24 inch banjo thread matches Holley's carburetor fuel inlet specification exactly. This configuration eliminates the need for bulky reducers or adapters, reducing potential leak points and simplifying installation. The compact 2.55 x 1.65 x 4.8 inch footprint fits tight engine bays without interference with headers or intake manifolds.

Street rodders, muscle car restorers, and drag racing enthusiasts benefit from this fitting when swapping carburetors or converting to aftermarket fuel delivery systems. It's particularly valuable when pairing a high-flow mechanical or electric fuel pump with a Holley four-barrel, ensuring supply-line capacity matches fuel demand at peak RPM. Installation requires only a wrench and proper thread sealant; the fitting accepts standard -6 AN hose with standard fittings. Weighing just 0.09 lbs, it adds negligible mass while delivering professional-grade reliability under sustained boost or nitrous oxide use.
