The honest FHST note applies, with the lift pump refilling at its own rate, so sustained max demand from both surge pumps eventually outruns the transfer; the GSS342 class matches street-and-track power targets, with the 450-class variants serving bigger builds. Wiring pairs a Radium DIY kit per pump circuit, and the 20-0736 access cover makes future service a lid-lift.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x FD RX-7 fuel hanger surge tank, GSS342 configuration (20-0450-02)\u003c\/li\u003e\n\u003cli\u003eVerify pump inclusion and wiring contents per the store listing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1992-1995 Mazda RX-7 (FD3S)\u003c\/li\u003e\n\u003cli\u003eCompanions: 20-0736 access cover, 20-0448 filter mount, 13B rails\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672708218947,"sku":"20-0951","price":750.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0450-02-29454189658182_e04fb427-292e-4e60-9370-88c28da083c3.jpg?v=1786717387","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-fuel-hanger-surge-tank-2-surge-pumps-1-lift-pump-walbro-gss342-1992-1995-mazda-rx-7-20-0450-02","provider":"Tuned by Shawn","version":"1.0","type":"link"}
