-8AN 7/8-20 Carb Fitting

The -8AN 7/8-20 Carb Fitting is a precision inlet adapter engineered for carbureted fuel systems running -8 AN hose plumbing. Designed by Peterson Fluid, this straight fitting bridges -8 AN male hose connections to the 7/8-20 male carburetor inlet port found on 700-series Holley carburetors and compatible fuel bowls. Built for high-performance street and racing engines where fuel delivery reliability and leak-free connections are non-negotiable, this fitting eliminates the need for tape-wrapped NPT threads or jury-rigged adapters that can fail under vibration and heat cycling.

Constructed from red anodized aluminum, the -8AN 7/8-20 Carb Fitting delivers lightweight durability while resisting corrosion in engine bay environments. The integrated 100-micron filter element protects your carburetor inlet from particulate contamination—a critical feature when fuel tanks lack baffles or when fuel system work stirs up debris. The straight configuration minimizes turbulence and pressure drop compared to 90-degree adapters, maintaining consistent fuel delivery across the RPM range. AN-style fittings use industry-standard O-ring face seal (ORFS) technology, ensuring repeatable, vibration-proof connections that won't weep or fail from thermal cycling.

This fitting is ideal for engine builders, restoration specialists, and carburetor tuners upgrading fuel systems on classic hot rods, street machines, and circle-track racing platforms. If you're converting an older gravity-fed or mechanical pump system to modern -8 AN braided hose, or replacing factory cast-iron distribution blocks with modular plumbing, the -8AN 7/8-20 Carb Fitting provides the exact adapter you need for Holley 700 carburetors. Installation requires standard -8 AN hose crimps on one end and a wrench fit to the 7/8-20 male port on the other; no modifications to existing carburetor or fuel lines needed.
