The Racer X Fabrication fuel rail kit for the 2012+ 1.4L Chevy Sonic is a perfect fit for enthusiasts that need additional fueling. The Racer X fuel rail kit allows for common AN fittings to be used instead of being stuck with the OEM fuel line fittings. The AN fittings let you add an external fuel rail pressure regulator and run a return line back to the OEM fuel tank. The fuel rail can be used with the OEM intake manifold or the Racer X Fabrication intake manifold. The fuel rail comes standard with a 6AN to 8AN fitting and an 8AN plug fitting. The fuel rail can also be used with the OEM fuel system by using a standard GM style fuel push on adapter. Fuel rail comes standard in a black anodized finish and our logo laser etched on the side.
