The rail pairs with the 20-0464 primary conversion to complete the engine, with the combo commonly plumbed through 8AN ORB adapter fittings and an FPD-R damper in the feed. Injector compatibility follows Radium's documentation, O-rings lubricated at install, and the first-start leak check runs before the first boost.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Anodized high flow secondary rail with mounting hardware\u003c\/li\u003e\n\u003cli\u003eInjectors and plumbing fittings NOT included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMazda 20B-REW three-rotor (1990-1995 Mazda\/Eunos Cosmo, swaps)\u003c\/li\u003e\n\u003cli\u003ePairs with the 20-0464 primary conversion rail\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672702615619,"sku":"20-0465","price":227.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0465-28318167433286_2442fe22-f0bb-4307-9e45-f23500c31bbe.jpg?v=1786717278","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-secondary-fuel-rail-mazda-20b-rew-20-0465","provider":"Tuned by Shawn","version":"1.0","type":"link"}
