A fuel rail kit built for the Barra six. The standard rail becomes a limitation once the engine is making meaningful power: internal volume and feed size were specified for factory injectors, and a set of large aftermarket injectors on a boosted build can pull rail pressure down at the far cylinders, leaning them out exactly when it hurts most. A larger-bore aftermarket rail steadies pressure across all six and gives you AN feed and return ports to plumb into a properly sized fuel system. Supplied as a kit with mounting hardware. Confirm your injector body length and O-ring size suit the rail before ordering.
