All three fuel rail ports are tapped for 8AN ORB.

8AN ORB Adapter Fittings can be found HERE.
8AN ORB Direct Mount Regulators can be found HERE.
8AN ORB Fuel Pulse Dampers can be found HERE.
Fuel Pressure Gauge Adapters can be found HERE.

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.

Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements.. The rail is CNC machined from solid 6061 aluminum and bright-dip anodized for a high quality surface finish. It is compatible with all fuel types including popular alcohol mixtures such as E85.

Fuel rail and fuel damper
Just installed the oem Evo X fuel rail kit with the FPD-R damper. Excellently made product and it finally fixed my surging idle. My car is pushing 500whp and idle was very touchy. Great product!
