Product SKU: RAD 20-0769-02

This 0.69" big bore fuel rail is CNC machined from billet 6061 aluminum, black anodized, and laser etched for a high quality surface finish. It is a direct replacement for the OEM fuel rail. A plumbing kit is available that provides all the necessary parts to install and plumb the fuel rail with OEM components.

This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM plastic spacers are reused to thermally insulate the fuel rail from the aluminum intake manifold.

This is the basic fuel rail, and only includes the fuel rail. Factory mounting hardware is re-used (consult install instructions for more info). This is ideal for high performance applications where the installer is going to build a custom fuel system. If using the factory regulator and fuel lines, consider purchasing the plumbing kit 20-0769-PK.

Injector Compatibility

Like the OEM fuel rails, the injector bores are 11mm ID so factory injectors are compatible. If using aftermarket injectors, make sure they are compatible with the stock fuel rail and are the same fitment as the OEM fuel injectors (height and O-rings).
