Hly Fuel Line Kit #6 Male Inlet

The Holley Fuel Line Kit #6 Male Inlet (XRP731006) is purpose-built for high-performance marine and racing engines running Holley 4150 carburetors. If you've spent years on the water or at the track, you know that fuel delivery reliability directly impacts performance and safety. This fuel line assembly eliminates guesswork by providing a complete, ready-to-install solution that meets the exacting demands of serious boaters and engine builders who refuse to compromise on fuel system integrity.

Built with braided stainless steel construction, the Holley Fuel Line Kit features a #6 AN male inlet connection and dual 7/8-20 inch male outlets—a proven configuration for carb fuel delivery on high-output engines. The braided stainless design resists corrosion from saltwater exposure and vibration damage that plagued older rubber hoses, while the color-coded lines (blue, red, and silver) streamline installation and reduce the risk of cross-plumbing fuel and return circuits. This dual-outlet design allows precise fuel distribution and return flow management, critical for maintaining carburetor bowl levels under acceleration, rough seas, or sustained high-RPM operation.

Anglers, boaters, and marine engine builders rely on this kit when retrofitting or rebuilding Holley 4150 fuel systems. It's ideal for inboard racing engines, high-horsepower outboard conversions, or any application where Holley carb fuel delivery must be bulletproof. Installation is straightforward: connect the #6 AN inlet to your fuel pump output, and route the dual outlets to carburetor fuel and return ports. Verify your carb's inlet and outlet thread sizes match before ordering—this kit is engineered for exact OEM compatibility with Holley 4150 specifications.
