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.
The fuel rail features four threaded ports that are all tapped for 8AN ORB fittings.
If building a custom fuel setup, appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.
