The Russell #6 Holley Fuel Line Kit without Gauge is a purpose-built carburetor fuel supply system designed for classic and high-performance engines running Holley 4150-series carburetors. This kit delivers fuel from tank to carburetor via braided stainless steel hose, eliminating weak points in older fuel delivery systems and providing the flow consistency that modern tuning demands. The kit arrives ready to install with all necessary fittings, saving hours of sourcing individual components from different suppliers.
The system features a 3/8-inch NPT female inlet connection at the fuel pump supply point and dual 7/8-20-inch male outlets that feed the primary and secondary fuel bowls of your Holley carburetor. Braided stainless steel construction resists corrosion, vibration damage, and pressure cycling far better than cloth-wrapped rubber hose, making it ideal for high-heat engine bays and vehicles subjected to frequent use. Color-coded hose sections (blue, red, and silver) simplify identification and routing during installation, reducing mistakes on first-time builds or carb swaps. The gauge-free design keeps costs down for builders who already have fuel pressure monitoring elsewhere in their system or plan to add it later.
This kit serves street rod builders, engine rebuilders, carburetor conversions, and restoration projects where original rubber hose has deteriorated or fuel pressure consistency matters. Whether you're converting a carbureted engine to Holley 4150 architecture, upgrading fuel delivery on a vintage rebuild, or assembling a performance carb setup, this complete fuel line solution eliminates guesswork. At 0.68 lbs, the kit is lightweight and compact enough for any engine bay layout.
Russell has long been recognized in the automotive fuel systems market for producing OEM-quality hose and fitting assemblies. This particular kit combines proven components into a matched set, ensuring compatibility between inlet sizing, outlet threads, and hose diameter from the start—a critical detail when fuel pressure or carburetor tuning is on the line.
