6an to 1/2-20 Fuel Pump Fitting - Black

The 6AN to 1/2-20 Fuel Pump Fitting in black anodized aluminum is a critical adapter for high-performance fuel system builds where precision AN connections meet OEM pump threads. Whether you're upgrading a carbureted hot rod, installing a modern EFI fuel system on a classic platform, or building a competition engine with custom fuel delivery, this straight adapter bridges the gap between 6 AN male fuel line fittings and 1/2-20 male pump inlet threads. Mechanics and fabricators rely on this fitting to maintain system integrity while simplifying plumbing in tight engine bays.

Manufactured by EARLS, a trusted name in performance fuel systems, this fitting is machined from aluminum and finished with black anodized coating for corrosion resistance and a clean appearance under the hood. The straight design eliminates unnecessary bends, reducing turbulence and pressure loss—critical factors when running higher fuel pump volumes or targeting consistent fuel pressure across wide RPM ranges. The 6 AN male inlet accepts standard -6 hose with proper fittings, while the 1/2-20 male outlet threads directly into most aftermarket and OEM fuel pump inlets. This compact adapter (1.2 x 0.8 x 3.05 inches) weighs just 0.03 lbs, adding negligible mass while solving a common compatibility challenge in fuel system design.

Engine builders upgrading fuel delivery systems, restorers retrofitting carbureted engines with modern fuel pumps, and fabricators working on custom fuel cells will find this fitting indispensable. It pairs seamlessly with aftermarket fuel regulators, surge tanks, and custom fuel cell setups where AN fittings provide superior leak resistance compared to barbed or push-lock alternatives. Installation is straightforward—hand-tighten initially, then use a wrench on the hex body to seat firmly without over-torquing the aluminum body. Verify your pump inlet thread size and fuel line AN size before ordering to ensure proper fitment in your specific application.
