BMW M50 Fuel Rail

Upgrade your classic BMW inline-6 with the Nuke Performance High-Flow Fuel Rail for the BMW M50 engine. Designed for serious performance builds, this lightweight rail features oversized internal bores, AN-8 ORB end ports, and an AN-6 ORB side port, allowing for maximum fuel delivery to support high-horsepower applications and modern EFI upgrades.

Compatible with Bosch EV14L 14mm injectors, this fuel rail is also equipped with Nuke’s patented injector safety clips, ensuring a secure, leak-free connection—even under extreme fuel pressure or track abuse.
