Dress up and open up your ZL1, CTS-V, or ZR-1 with Holley Hi-Flow Fuel rails. The bright dip, black anodized rails come with laser etched EFI logo for long-lasting good looks and are a direct replacement for the rails on the factory blower or any other supercharger that was designed to use OEM rails. For perfect sealing, the 534-285 kit has been machined to accept -8 (3/4-16) ORB ports which use O-ring fittings. But, to utilize your factory fuel line quick-connect, just add P/N 534-211 adapter kit for a quick and easy install. The included brackets are for factory-height injectors (33.60mm).
