Description

The Radium Engineering Mazda MZR / Ford Duratec Fuel Rail Plumbing is designed so it replaces or upgrades the factory fuel rail with a high-flow rail designed for performance injectors and AN/ORB plumbing. The larger, purpose-built fuel path is useful on modified engines where injector choice, fuel volume, and serviceable external plumbing matter more than the stock rail layout.

For Ford Duratec, it is intended to integrate with the vehicle-specific layout rather than serve as a universal substitute. Injector height, upper/lower O-ring diameter, and plumbing requirements vary by engine. Match the exact application and injector configuration.
