A collector box with two 355 lph one-way fill valves keeps the pumps fed through hard cornering, while a pressure-relief-valve venturi jet pump pulls fuel across from the passive side of the saddle tank without restricting the return line. Pumps sold separately; pick the configuration built for yours.

Wiring follows the usual Radium pattern: single-pump installs can reuse the OEM pump controller circuit, but high-flow pumps draw real current, so upgraded wiring (one DIY kit per pump) is the recommendation. Two fitment gotchas matter here and both come straight from Radium. First, the 2014-2018 Forester XT and 2015-2021 WRX share the tank but not the fuel unit, so they need the 20-0850 FA20 fuel level sender adapter, sold separately. Second, those same FA20 cars are returnless from the factory; the OEM in-tank regulator is discarded with this conversion, so an aftermarket FPR is required to complete the system. Also note that several compatible AEM pumps lack a check valve; if pressure hold after shutdown matters, Radium's check valve is the fix.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Anodized billet fuel pump hanger in selected pump configuration\u003c\/li\u003e\n\u003cli\u003eCollector box with two 1-way fill valves and PRV venturi jet pump\u003c\/li\u003e\n\u003cli\u003ePre-installed SAE quick connect fittings on all three ports\u003c\/li\u003e\n\u003cli\u003eSubmersible fuel tubing, stainless electrical terminals, and stainless hardware\u003c\/li\u003e\n\u003cli\u003eFuel pumps NOT included, sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2008-2014 Subaru WRX and 2008-2021 Subaru STI\u003c\/li\u003e\n\u003cli\u003e2008-2014 Subaru Impreza and Forester (all)\u003c\/li\u003e\n\u003cli\u003e2005-2009 Subaru Legacy and Outback (all)\u003c\/li\u003e\n\u003cli\u003e2015-2021 Subaru WRX and 2014-2018 Forester XT (require 20-0850 sender adapter and an aftermarket fuel pressure regulator, each sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Walbro GSS342 or AEM 50-1200","offer_id":43672689573955,"sku":"20-0780-00","price":493.95,"currency_code":"USD","in_stock":true},{"title":"Deatschwerks DW400","offer_id":43672689606723,"sku":"20-0781-00","price":512.95,"currency_code":"USD","in_stock":true},{"title":"Walbro F90000267\/274\/285","offer_id":43672689639491,"sku":"20-0782-00","price":512.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-28603885584454_3c7ad8c9-d9cf-4c09-8a25-951082b3f2e2.jpg?v=1786717059","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-fuel-pump-hanger-2015-2021-subaru-wrx-sti-20-078x-xx","provider":"Tuned by Shawn","version":"1.0","type":"link"}
