#8 Pro Stock Fuel Line Kit 4150

The #8 Pro Stock Fuel Line Kit 4150 by FRAGOLA is purpose-built for carbureted high-performance engines and racing applications where fuel delivery reliability is non-negotiable. This kit serves serious engine builders and mechanics who understand that fuel system integrity directly impacts combustion consistency, engine response, and overall reliability under demanding conditions. Whether you're assembling a circle-track racer, street performance build, or restoration project running a Holley 4150-series carburetor, this fuel line assembly eliminates guesswork and delivers OEM-quality components in one integrated package.

This kit features braided stainless steel hose construction that resists fuel degradation, vibration wear, and high-temperature cycling—critical factors in engines producing sustained heat. The #8 AN (5/8-inch) male inlet accepts fuel pump discharge without restrictive fittings, while dual 7/8-20 inch male outlets distribute fuel symmetrically to both carburetor fuel bowls, ensuring even delivery and minimizing vapor lock risk. The stainless braid and blue/silver finish not only provide corrosion resistance but also allow visual inspection for leaks or hose deterioration during pre-event checks. This design philosophy—redundancy and visibility—reflects decades of FRAGOLA's fuel system engineering for competitive motorsports.

Racers, engine builders, and restorers targeting Holley 4150 carburetor platforms benefit most from this pre-assembled solution, as it eliminates custom hose runs and potential leak paths introduced by field fabrication. Installation is straightforward: connect the single inlet to your fuel pump discharge, then route the dual outlets to each bowl inlet on the carburetor. The compact dimensions (3.5 x 1.2 x 13.05 inches) facilitate engine bay fitment without compromising underhood clearance. Whether upgrading an aging fuel system or specifying components for a fresh build, this FRAGOLA kit ensures compliance with pro stock fuel delivery standards while delivering the craftsmanship expected in competition-grade fuel systems.
