Kaloeou Braided AN6 Dual-Feed Carb Fuel Line for Holley 4150 — Black Anodized Aluminum, Pre-Assembled with AN6 Hoses

This fuel line assembly replaces the factory fuel log with a durable, high-flow aluminum manifold and AN6 stainless-braided hoses designed for street, strip, and track applications. Finished in black anodize and supplied ready-to-install with stanchions and fittings, the unit offers a cleaner look and a more dependable, balanced supply to your Holley 4150 series carburetor. It accommodates a 3/8" NPT female inlet and includes 1/8" NPT ports for fuel pressure monitoring.

How does this dual-feed fuel line improve carburetor fuel delivery?

The Kaloeou dual-feed log feeds both sides of the Holley 4150 bowl simultaneously, promoting even fuel distribution under acceleration and high-RPM loads. Balanced supply reduces the chance of leaning on one side of the carb and helps maintain consistent metering across all cylinders.

• Dual AN6 braided hoses for parallel flow to each bowl side
• 3/8" NPT female inlet for common high-flow fittings
• 1/8" NPT ports for fuel pressure gauge installation
• 9-5/16" center-to-center mounting to match Holley 4150 specifications

Will this fit my Holley Dominator or 4150 carburetor?

This unit is made for Holley 4150-style carburetors featuring 7/8"-20 fuel bowl inlet threads and a 9-5/16" center-to-center spacing. It is not universal — verify that your carb’s inlet thread and spacing match before ordering to ensure a direct bolt-on installation.

• Designed for Holley 4150 series with 7/8"-20 thread
• Matches 9-5/16" center-to-center spec for correct fitment
• Includes stanchions to secure to the carburetor flange
• Check thread specs and model compatibility prior to purchase

What materials and durability features does it offer?

The fuel log body is lightweight, high-density aluminum with a protective black anodized finish to resist corrosion and road wear. Hoses are stainless-steel braided to withstand heat, abrasion, and modern fuel additives while maintaining OEM-level reliability in performance conditions.

• Black anodized aluminum fuel log resists corrosion
• Stainless-braided AN6 hoses for abrasion and heat resistance
• Quality fittings sized for performance fuel systems
• Pre-assembled for reduced installation errors

How easy is installation and what should I watch for?

The kit ships pre-assembled so most installers can bolt it in place with basic hand tools; stanchions and fittings are included to secure the assembly to the carb. If hose ends show minor seepage, a light wrap of PTFE tape or sealing lace is recommended; hoses can be trimmed for custom-length runs.

• Pre-assembled braided dual line for quick bolt-on installation
• Includes stanchions and appropriate fittings for Holley 4150
• Trim hoses if custom length is needed, then reseal ends
• Manufacturer offers one-year support for fitment or usage questions
