#6 Holley Fuel Line Kit w/o Gauge Endura

The #6 Holley Fuel Line Kit w/o Gauge Endura is a purpose-built fuel delivery solution for carbureted street and performance engines running Holley 4150-series carburetors. Designed for builders and enthusiasts who demand reliability in high-vibration automotive environments, this kit eliminates guesswork from fuel line routing by providing matched components engineered to work together. Whether you're rebuilding a classic muscle car, fabricating a custom hot rod, or upgrading a vintage street machine, this fuel line assembly addresses a critical systems requirement with proven durability and straightforward installation.

Built by Russell, a trusted name in fuel system engineering, the #6 Holley Fuel Line Kit features braided stainless steel hose construction that resists vibration-induced cracking, fuel weeping, and corrosion—common failure points in traditional rubber hose setups. The kit includes a 3/8-inch NPT female inlet connection that mounts directly to the carburetor fuel bowl, dual 7/8-20 inch male outlets for flexible fuel line adapters, and pre-assembled routing geometry that minimizes kinks and pressure drops. Stainless braiding protects against abrasion when routed near engine bay hot spots, headers, or moving components, while the sealed design maintains pressure integrity across a wide operating temperature range typical of fuel-injected and carbureted platforms alike.

This kit is ideal for Holley 4150 carburetor installations on street rods, circle track vehicles, and restoration projects where original rubber fuel lines have degraded or require modernization. The dual outlet design accommodates fuel return lines on systems using a return-style regulator, a configuration common in high-performance and fuel-pressure-regulated carburetors. Installation requires basic mechanical skill and standard hose clamp or AN fitting tools; the lightweight assembly (0.72 lbs) integrates easily into existing engine bays without adding unwanted bulk or weight penalty.
