xRULLINE AN6 Dual-Feed Braided Fuel Line for Holley 4150
Designed for performance carburetor tuning, the RULLINE AN6 Dual-Feed Braided Fuel Line blends a precision aluminum body with a stainless steel nylon braided hose. This robust setup provides a clean, efficient fuel path to the carburetor, while the 0-160 psi gauge enables on‑the‑spot monitoring during tuning sessions. Built to work with Holley 4150 base carburetors and similar dual‑feed systems, it offers a reliable upgrade over older lines and helps maintain stable fuel pressure across RPM ranges.
The dual‑feed design supports steady fuel supply to multiple intake paths or higher‑demand engines, reducing the risk of lean spots and ensuring a consistent flow. The aluminum body is lightweight yet sturdy, resisting heat and vibration, while the braided hose adds wear resistance and heat tolerance. This combination aims for a long service life under real‑world driving conditions, backed by professional manufacturing and rigorous testing to ensure dependable performance.
