The 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.

Depending on the vehicle's country of origin, this fuel rail kit is compatible with the following Subaru models: 

2002-2014 Impreza WRX (that came with top feed injectors)
2007-2018 Impreza WRX STi (that came with top feed injectors) 
2007-2012 Legacy GT (that came with top feed injectors)
2007-2012 Outback XT (that came with top feed injectors)
2006-2013 Forester XT (that came with top feed injectors)
2005-2006 Saab 9-2X Aero (that came with top feed injectors)
Subaru JDM Ver8-9 EJ207 (when used with this adapter HERE)
Subaru 2.5i EJ253 (when used with this adapter HERE)

Manufactured with a large internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from solid 6061 aluminum, black anodized, and laser etched for a high quality surface finish. All 3 ports on each fuel rail are tapped with -8AN ORB.

For thermal insulation, machined phenolic spacers and washers are included to completely isolate the fuel rail from heat transfer via the TGV housings and mounting bolts.  

Two sets of these press-fit phenolic spacers (8 total) and matching hardware are included to suit different height fuel injectors. All must use 11mm diameter upper O-rings just like the OEM Subaru top feed injectors. The fuel rail kits are compatible with all fuel types including popular alcohol mixtures such as E85.

20-0478 Fuel Rail Plumbing, Subaru EJ 

This engine bay plumbing kit is designed to be used with Radium fuel rails and includes all the necessary fittings, hose and other components to complete the installation and have a complete operating system.  This kit plumbs the fuel rails in series, beginning and ending at the factory hard lines near the LH strut tower.  It is compatible with all factory hard lines, whether SAE quick connect or hose barb connections. An adjustable Radium Direct Mount Regulator (DMR) is included along with a Radium fuel pressure gauge to calibrate the DMR. The 6AN swivel adapter fittings for the fuel rail ports are low profile making them ideal for the tight spaces associated with the EJ motor. Pushlock hose-ends are easy to work with, making installation quick and painless. A variety of hose-ends are provided so the installer can custom tailor the fuel line routing for their specific vehicle.

Unlike standard fuel hose that degrades with alternate fuels, the provided Vapor Shield hose is compatible with gasoline and alcohol blends, including E85. Furthermore, the hose has a special construction that prevents vapor permeation. And unlike PTFE, this fuel hose absorbs unwanted fuel injector pulses and has an improved bend radius. 

-Direct Mount Regulator
-6AN PushLok Hose Ends
