BMW S50 Fuel Rail

Upgrade your BMW S50B30US engine with the Nuke Performance High-Flow Fuel Rail, built specifically for the North American S50 US platform. Precision CNC-machined in Sweden, this fuel rail delivers outstanding flow capacity through its oversized internal bore and dual AN-8 ORB main ports, making it the ideal fueling solution for high-performance and E85-powered builds.

Designed for use with Bosch EV14L (14mm) injectors, this rail is also equipped with Nuke’s proprietary injector safety clips, engineered to provide a secure, leakproof seal—even under high pressure or crash conditions. It includes mounting brackets for direct fitment on all BMW S50 US intake manifolds and also works with M50 intake setups.

An additional AN-6 ORB side port allows for flexible plumbing of sensors, returns, or auxiliary systems. Whether you’re running high boost or planning a full E85 conversion, this fuel rail is built to meet the demands of modern motorsports.
