Dual Feed Kits 6AN Fits Holley 7/8-20 Inlet

The Dual Feed Kits 6AN Fits Holley 7/8-20 Inlet from Redhorse Performance is purpose-built for fuel system builders and performance enthusiasts who demand reliability in high-flow carburetor and EFI fuel delivery systems. This dual feed kit addresses the critical need for balanced fuel distribution in Holley carburetors, particularly when running multiple fuel pumps or transitioning to modern fuel management systems. Whether you're upgrading a classic muscle car, building a street rod, or tuning a competition engine, this adapter kit ensures consistent fuel supply pressure and eliminates the risk of carburetor starvation under acceleration.

Engineered with precision ANT (Automotive Nanometer Thread) technology, the 6AN hose adapter interfaces seamlessly with the industry-standard Holley 7/8-20 inlet port found on most Holley 4150, 4160, and similar carburetor models. The dual feed design allows simultaneous fuel input from primary and secondary circuits, maintaining optimal pressure distribution across the float bowls and preventing fuel starvation during hard cornering or extended full-throttle acceleration. Redhorse Performance components are manufactured from billet aluminum and stainless steel, ensuring corrosion resistance and durability in both street and strip applications. The compact 14.2-inch length and 0.63-pound weight minimize installation complexity while providing a clean, professional appearance in engine bays.

This kit is ideal for fuel system upgrades involving carburetor conversion kits, dual fuel pump installations, or carb-to-EFI transitions where fuel pressure regulation and distribution are non-negotiable. Installation requires standard hose clamps and basic hand tools; compatibility extends to any fuel system with 6AN hose sizing and Holley 7/8-20 threaded inlets. Mechanics and engine builders performing carburetor restoration, performance tuning, or fuel system modernization will appreciate the engineering precision and failsafe redundancy built into this adapter, making it an essential component for any serious fuel delivery upgrade.
