Usage
This reducer excels in automotive fuel systems, especially for LS engine swaps, aftermarket fuel line upgrades, and high‑flow cooling circuits. Its wide temperature range of –40°F to 250°F and maximum working pressure of 1,500 PSI make it suitable for both street and track use. Install it between a larger AN10 fuel rail and a smaller AN6 line to ensure a secure, high‑flow connection without compromising safety.
