Carb Fitting w/washer 7/8-20 to -6 Female Blue

The Carb Fitting w/washer 7/8-20 to -6 Female Blue from ALLSTAR PERFORMANCE is a precision carburetor inlet fitting engineered for fuel system plumbing on Holley carburetors and compatible fuel delivery systems. Designed for custom and performance builds, this straight adapter transitions from the carburetor's 7/8-20 male port to a -6 AN female inlet, enabling clean, leak-free fuel line connections. Built for enthusiasts and professional engine builders who demand reliability under high-fuel-flow demand, this fitting eliminates improvised adapters and reduces the risk of fuel system failures that plague stock or poorly matched components.

Machined from aluminum and finished in blue anodizing, the Carb Fitting w/washer 7/8-20 to -6 Female Blue provides corrosion resistance and a clean aesthetic in engine bays. The integrated washer seats properly against the carburetor inlet, distributing clamping force and preventing leaks under vibration and thermal cycling. At 3.5 inches long with a compact 4 x 1.1 x 7.05-inch footprint, this fitting accommodates tight engine compartment layouts without requiring exotic fuel line routing. The straight design minimizes turbulence in fuel delivery, critical for carburetor tuning and fuel atomization on naturally aspirated and forced-induction applications.

This fitting is essential for anyone upgrading carburetor fuel systems, converting to external fuel pumps, or building show-quality engine bays where safety and appearance matter equally. It pairs seamlessly with -6 AN braided hoses and stainless steel fuel line kits, simplifying plumbing on vintage hot rods, street machines, and circle-track engines. Installation requires only a wrench and basic fuel system knowledge; the washer ensures a tight seal without over-torquing, protecting the carburetor's aluminum casting. Compatibility spans Holley 4150, 4160, and similar carburetors with 7/8-20 inlets, making it a universal solution for Chevy, Ford, Mopar, and LS engine platforms.
