Holley Quad Fuel Line Chrome 9-5/16in Center

The Holley Quad Fuel Line Chrome 9-5/16in Center is a premium carburetor fuel delivery component engineered for high-performance street and racing applications. Designed by Racing Power Co-Packaged, this center fuel line serves as the critical manifold connecting your Holley carburetor's fuel bowl outlets to the main fuel rail distribution system. This component is essential for enthusiasts running multi-carburetor setups or upgrading their fuel delivery architecture to handle increased flow demands and consistent pressure regulation across naturally aspirated and boosted platforms.

Constructed with polished chrome plating, this fuel line combines corrosion resistance with the aesthetic appeal demanded by show-quality engine bays and competition vehicles. The 9-5/16-inch center dimension establishes the precise spacing required for proper fuel distribution geometry in quad-carb configurations and fuel manifold assemblies. Chrome-plated steel construction ensures durability under constant fuel exposure and temperature cycling, while the precision-engineered bore diameter maintains laminar flow characteristics critical for stable jetting and consistent fuel atomization. The lightweight design—just 0.77 lbs—minimizes parasitic weight while eliminating harmonic vibration points that can compromise fuel delivery consistency.

This fuel line is ideal for serious carburetor builders, engine builders, and vintage hot rod restorers upgrading fuel systems on competition-spec or street performance engines. Technicians installing multiple Holley carburetors—common in small-block Chevy, big-block applications, and vintage drag racing platforms—rely on properly sized center fuel lines to eliminate lean-out conditions and fuel starvation during wide-open throttle events. Installation requires standard fuel line fittings and hose connections; verify center dimension compatibility with your specific carburetor spacing and fuel manifold layout before ordering. This component pairs seamlessly with Racing Power Co-Packaged fuel rails, manifolds, and carburetor mounting hardware.
