PORTS AND FITTINGS

The fuel rail ports are tapped for 8AN 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.

The Subaru Impreza 2.5i (EJ253) and JDM Ver8/9 (EJ207) STi intake manifolds are great solutions for eliminating the tumble generator valves on modified engines.

These Radium Engineering adapters permit the use of any OEM or aftermarket Subaru top feed fuel rail (such as Radium 20-0479) to be used.

The slotted hole positioning below is specifically for the Subaru EJ253 intake manifold. Moving the adapters outwards allows fuel rail fitment for the Ver 8/9 JDM EJ207 STi intake manifold.
