The 11mm ID injector bores match OEM, so factory or equivalent aftermarket injectors drop in, and the rail mounts on the OEM studs, nuts, and insulating spacers. A provision to reuse the OEM fuel pressure regulator keeps stock-plumbing builds simple, while the ORB ports open the door to Radium's DMR regulator and FPD-R damper. All fuels welcome, E85 included.\u003c\/p\u003e\n\u003ch3\u003eWhat You'll Feel\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFuel volume on tap for every B-series power level, from bolt-on VTEC to boosted E85\u003c\/li\u003e\n\u003cli\u003eA rail that grows with the build: OEM FPR today, Radium DMR direct-mount regulator tomorrow\u003c\/li\u003e\n\u003cli\u003eInstrumentation ready, with the 1\/8\" NPT port hosting a gauge or sensor when the OEM FPR departs\u003c\/li\u003e\n\u003cli\u003eInjector seals that survive, with true 11mm OEM-spec bores\u003c\/li\u003e\n\u003cli\u003eA factory-clean mount on the original studs and insulating spacers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCNC machined 6061 aluminum with large internal bore; anodized and laser etched\u003c\/li\u003e\n\u003cli\u003ePorts tapped for 8AN ORB and 1\/8\" NPT\u003c\/li\u003e\n\u003cli\u003e11mm ID injector bores compatible with factory or OEM-equivalent aftermarket injectors\u003c\/li\u003e\n\u003cli\u003eProvision to reuse the OEM fuel pressure regulator; open 1\/8\" NPT port for sensors or a plug when not used\u003c\/li\u003e\n\u003cli\u003eAccepts the Radium DMR 8AN ORB direct-mount regulator and FPD-R 8AN ORB pulse damper (sold separately)\u003c\/li\u003e\n\u003cli\u003eMounts with OEM studs, nuts, and insulating spacers; all fuel types including E85\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Details\u003c\/h3\u003e\n\u003cp\u003eThe dual-thread port layout is the flexibility play. ORB ports carry the fuel system: feed, return, a direct-mount DMR regulator in the end port, or an FPD-R damper in the top port. The NPT port carries the data, commonly a Radium 0-100 psi gauge, straight or on a 90 degree elbow for visibility. Injector guidance follows Radium's standard line: factory or OEM-equivalent only, with your injector supplier confirming dimensions, since Radium specifies nothing beyond 'OEM equivalent.' This is the rail-only kit with mounting hardware, ideal for custom fuel systems, and extra fittings, hose, and plumbing complete the install; Radium's optional OEM-configuration plumbing kit (sold separately) is the plug-and-play route for stock-style plumbing. Leave clearance around ports destined for regulators, gauges, or dampers.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Anodized, laser etched B-series fuel rail\u003c\/li\u003e\n\u003cli\u003eMounting hardware (reuses OEM studs, nuts, and insulating spacers)\u003c\/li\u003e\n\u003cli\u003eFittings, hose, and plumbing sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHonda DOHC B-Series engines (B16, B18, B20) in Civic, Del Sol, Integra, and swap applications\u003c\/li\u003e\n\u003cli\u003eFactory or OEM-equivalent fuel injectors\u003c\/li\u003e\n\u003cli\u003eAll fuel types including E85\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672693080131,"sku":"20-0370-02","price":142.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0370-02-20-0370-02-fuel-rail-only-12018444468294.jpg?v=1786717098","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-fuel-rail-honda-b-series-20-0370","provider":"Tuned by Shawn","version":"1.0","type":"link"}
