Holley EFI Billet Fuel Rail Kit (09-13 Corvette C6 ZR1)

Description

High-Performance Fuel Delivery. The Holley EFI Billet Fuel Rail Kit replaces the OEM fuel rails for LSA and LS9 engines with a high-flow billet aluminum design. It enhances fuel flow capacity, supporting high horsepower applications, and is intended for supercharged engines that use factory-style rails, making it ideal for performance upgrades and engine dress-up.

Construction and Appearance. Made from billet aluminum, the fuel rails feature a bright dip, black anodized finish for durability and corrosion resistance. They are laser-etched with the EFI logo to provide a sharp, long-lasting appearance that complements high-performance engine bays.

Installation. The installation requires no drilling and serves as a direct replacement that maintains OEM-level fitment and function. It is compatible with factory fuel line quick-connects using an optional adapter, ensuring a straightforward installation process.

Application. These fuel rails are specifically designed to fit the 09-13 Corvette C6 ZR1 and are tailored for the OEM blower setup used in this model generation.
