The fuel rail end ports are tapped for 8AN ORB and the center port is tapped for 6AN ORB.

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.

Just fuel rails and mounting brackets. Fittings and adapters sold separately. This option is ideal for users wanting to do their own custom lines and plumbing.

As a compliment, consider purchasing 20-0353 Radium ECU Mount. This prevents the need to cut the OEM steel ECU mount and permits easy access to the RH fuel rail.
