Radium Engineering Fuel Rail Plumbing Kit (Series) Subaru WRX / STI (EJ20 / EJ25)

Radium Engineering Fuel Rail Plumbing Kit (Series) - Subaru WRX / STI (EJ20 / EJ25)

This Radium Engineering fuel rail plumbing kit (SKU 20-0978) provides all the under-bonnet fuel plumbing for Radium top feed fuel rails on Subaru EJ20 / EJ25 engines, feeding the rails in a series layout. It connects to the factory feed and return hard lines near the left-hand strut tower using SAE quick connects or the older hose barb connections.

An adjustable RA-series Direct Mount Regulator (DMR) is included, along with a 0–100 psi Radium fuel pressure gauge that can be fitted at any 6AN junction before the regulator using the supplied adapter. Low-profile 6AN swivel rail fittings suit the tight EJ engine bay, reusable PushLok hose ends make it easy to add parts such as a flex fuel sensor, and the 6AN hose can be cut and assembled with standard tools.

Note: Suits Radium EJ fuel rails (excluding the 20-0499 dual port injector rail kit). Early models with an engine bay mounted fuel filter should refer to the installation instructions. Series and parallel (20-0984) kits perform equally well – the choice is personal preference. Installation by a professional is recommended.
