The \u003cstrong\u003eRadium Engineering Fuel Rails for GM LS9\/LSA Engines\u003c\/strong\u003e are the upgrade-rail answer: two rails CNC machined from 6061 aluminum, black anodized and laser etched, each carrying six 8AN ORB threaded ports for twelve in all. Polished stainless steel brackets attach to the factory rail mounting points with no vehicle modifications, the 14mm ID injector bores match OEM so factory injectors and clips carry over, and everything is compatible with all fuels including E85. Four 8AN ORB plugs are included for the end ports that sit too close to surrounding components to use.\u003c\/p\u003e\n\u003ch3\u003eWhat You'll Feel\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRail volume and port access sized for what a supercharged V8 actually flows\u003c\/li\u003e\n\u003cli\u003eTwelve ports of plumbing freedom: feeds, crossovers, dampers, gauges, sensors\u003c\/li\u003e\n\u003cli\u003eA no-modification install on factory mounting points with stainless brackets\u003c\/li\u003e\n\u003cli\u003eFactory injectors and clips reused in true 14mm OEM-spec bores\u003c\/li\u003e\n\u003cli\u003eE85 confidence across the whole assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2x fuel rails CNC machined from 6061 aluminum, black anodized, laser etched\u003c\/li\u003e\n\u003cli\u003eSix 8AN ORB ports per rail (12 total) for optional adapters and accessories\u003c\/li\u003e\n\u003cli\u003ePolished stainless steel mounting feet attach to factory rail mounting points; no vehicle modifications\u003c\/li\u003e\n\u003cli\u003e14mm ID injector bores compatible with factory injectors, with provisions for the factory injector clips\u003c\/li\u003e\n\u003cli\u003eUpgrade rail: OEM or OEM-equivalent injectors only (matching height and O-ring dimensions)\u003c\/li\u003e\n\u003cli\u003e4x 8AN ORB plugs included for end ports blocked by nearby components; all fuel types including E85\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Details\u003c\/h3\u003e\n\u003cp\u003eRadium classifies this as an upgrade rail, which sets the injector rule: factory injectors reinstall directly, and any upgrade must be OEM-equivalent in height and upper\/lower O-ring dimensions, with flow rates chosen by your tuner and dimensions confirmed by the injector manufacturer, since Radium makes no injector recommendations. The port count is the customization canvas, and Radium's advice is worth following literally: mock the rails up on the engine before purchasing adapter fittings and accessories, because surrounding engine components can interfere with access to some ports and the mock-up tells you which of the twelve are truly available on your particular car. For stock-style plumbing, Radium's separate LS9\/LSA plumbing kit adapts the OEM feed line via SAE quick connect into two 6AN PushLok lines supplying each rail, with plugs for everything unused; sold separately.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2x Black anodized laser etched aluminum fuel rails\u003c\/li\u003e\n\u003cli\u003e4x Fuel rail end fittings, 8AN ORB plugs\u003c\/li\u003e\n\u003cli\u003e4x Stainless steel mounting feet\u003c\/li\u003e\n\u003cli\u003e12x Stainless steel hardware\u003c\/li\u003e\n\u003cli\u003ePlumbing kit (20-0545) and additional adapter fittings sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2009-2013 Chevrolet Corvette ZR1 (LS9)\u003c\/li\u003e\n\u003cli\u003e2012-2015 Chevrolet Camaro ZL1 and 2009-2015 Cadillac CTS-V (LSA)\u003c\/li\u003e\n\u003cli\u003e2013-2017 HSV GTS, Clubsport R8, Maloo R8, GTSR, GTSR Maloo, GTSR W1, Senator Signature; 2014+ Equus Bass 770\u003c\/li\u003e\n\u003cli\u003eMock up rails before buying adapter fittings to verify port access\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672693702723,"sku":"20-0362","price":427.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-29420034424902_9c10a32b-2c88-4a93-be48-0b94a09c7231.jpg?v=1786717113","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-fuel-rails-and-plumbing-kit-2009-2013-chevrolet-corvette-zr1-2012-2015-chevrolet-camaro-zl1-and-2009-2015-cadillac-cts-v-20-0362","provider":"Tuned by Shawn","version":"1.0","type":"link"}
