Radium Engineering 08-21 Subaru WRX STi (EJ257 Only) RA-Series Fuel Pressure Regulator Kit
2008+ STi Fuel Pressure Regulator Kit by Radium This kit is made for use in the USDM 2008-2017 Subaru WRX STi (EJ257 only) and replaces the OEM fuel pressure regulator and damper assembly.
The factory STi fuel line routing uses a quasi dead-end system that circulates fuel through the regulator, bypassing the engine.
Fuel is only routed to the engine when there is demand.
Features
- Replaces the factory regulator and re-routes fuel to cycle through the rails before reaching the regulator
- Adjustment from 20psi-up with a 1:1 vacuum reference
- Interchangeable orifices allow the user to tune the regulator for any fuel pump flow
- Installs in the same location as the OEM fuel pressure regulator
- Includes vacuum hose and fittings to re-route the vacuum reference line from the #4 cylinder runner to the intake manifold plenum for a more stable vacuum signal
