The FHST's surge architecture keeps a full reservoir at the pump regardless of migration, with the GSS342\/AEM class covering builds through strong bolt-on territory; forced induction and E85 ambitions step up to the 20-1832 Walbro-450\/DW440 version instead. Each installed pump wants a Radium DIY wiring kit so current matches flow, and the platform coverage spans the Z33 350Z and V35 G35 sharing this hanger design.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x FHST fuel hanger surge tank assembly\u003c\/li\u003e\n\u003cli\u003eProvisions and hardware for the supported pumps\u003c\/li\u003e\n\u003cli\u003eFuel pumps NOT included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2003-2006 Nissan 350Z (Z33) and 2003-2006 Infiniti G35 (V35, per Radium's platform coverage)\u003c\/li\u003e\n\u003cli\u003e20-1830: Walbro GSS342 \/ AEM 50-1200 class; 450-class version is 20-1832\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672700551235,"sku":"20-1830","price":712.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0830-00-29454205452358_f49e323e-43c8-4da6-8e4a-979d86bc96f9.jpg?v=1786717230","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-fuel-hanger-surge-tank-walbro-gss42-aem-50-1200-pumps-not-included-2003-2006-nissan-350z-20-0830-00","provider":"Tuned by Shawn","version":"1.0","type":"link"}
