This kit reverses that: feed enters the rails, flows through them, then meets the regulator before returning to the tank, so the injectors always sit in moving, pressure-controlled fuel. The included vacuum hose and fittings relocate the regulator's reference signal from the #4 cylinder runner to the intake manifold plenum, trading a pulsing single-runner signal for a stable average that the diaphragm can actually track. Adjustment is where the RA-series stands apart: turn the knob and feel each detent click off roughly 1 psi, no wrenches, no jam nut, no set screw. Installation happens in the stock regulator location with the OEM lines, and if you want eyes on your base pressure, the spare 8AN ORB port takes Radium's 90-degree gauge kit. This kit is specific to the USDM EJ257 STI, so 2015-2021 WRX FA20DIT owners need to look elsewhere.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x RA-series direct mount fuel pressure regulator (black)\u003c\/li\u003e\n\u003cli\u003eMounting and adapter hardware for the OEM regulator location\u003c\/li\u003e\n\u003cli\u003eVacuum hose and fittings to re-route the reference line to the intake manifold plenum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2008-2021 Subaru WRX STI (USDM, EJ257 engine only)\u003c\/li\u003e\n\u003cli\u003eNot compatible with 2015-2021 Subaru WRX (FA20DIT)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672688427075,"sku":"20-0965","price":256.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0965-00-30957279871046_18b93f96-e395-43ab-9622-00a564510747.jpg?v=1786717051"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/collections\/WRX_STi_01-05.png?v=1703120699","url":"https:\/\/www.tunedbyshawn.com\/collections\/wrx-sti-01-05.oembed?page=2","provider":"Tuned by Shawn","version":"1.0","type":"link"}
