EFI Fuel Rail Kit - GM LS Pro Flo XT

The EFI Fuel Rail Kit – GM LS Pro Flo XT by Edelbrock is purpose-built for enthusiasts upgrading their LS-platform engines to modern electronic fuel injection systems. Whether you're converting a classic muscle car, modernizing a swap project, or optimizing fuel delivery on a naturally aspirated or boosted LS engine, this fuel rail assembly provides the infrastructure needed for consistent, reliable fuel pressure distribution across all eight injectors. Edelbrock's Pro Flo XT platform is trusted by serious engine builders and tuners who demand precision fuel management in high-performance applications.

This fuel rail kit features precision-engineered passages designed to minimize pressure drop and deliver uniform fuel flow to each port, critical for cylinder-to-cylinder consistency and idle quality. The assembly integrates mounting points that align with LS-series cylinder head port locations, eliminating fitment guesswork and ensuring a clean, factory-style installation. Edelbrock's design accounts for the unique geometry of LS engines, with fuel pressure regulation and damping built into the system to reduce noise and stabilize delivery across varying throttle positions and boost conditions. The compact, lightweight construction—weighing just 2.75 lbs—keeps engine bay clutter minimal while maintaining rigidity and thermal stability under sustained operation.

This rail excels in street applications, track cars, and engine swaps where OEM fuel system architecture doesn't exist or must be replaced. Mechanics and fabricators appreciate the plug-and-play design that integrates seamlessly with Edelbrock's Pro Flo XT EFI components, eliminating the need for custom welding or adapter fabrication. Compatible with standard LS1, LS2, LS3, and Gen IV platforms, the kit works equally well with carbureted-to-EFI conversions and complete engine transplants. Installation pairs easily with aftermarket ECUs, and the rail's configuration supports naturally aspirated through high-boost applications when matched with appropriately sized injectors and pump capacity.
