To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

Fuel Injector Compatibility

What's Included? 

This is the basic fuel rail kit, and only includes the fuel rail and the mounting hardware. This is ideal for custom applications where the installer is going to build custom fuel system plumbing.

Product Description

This fuel rail is CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish. It is a direct replacement for the OEM fuel rail. Plumbing kits are available that provide all the necessary parts to install and plumb the fuel rail with OEM components. The kits are compatible with all fuel types including popular alcohol mixtures such as E85. The OEM plastic spacers are reused and washers are included to thermally insulate the fuel rail from the aluminum intake manifold.
