The injector bores are 14mm ID exactly like the factory rail, so OEM injectors carry straight over, and provisions for the OEM injector retaining clips are built in. Three 8AN ORB ports, one at each end and one in the center, open the door to proper AN plumbing.

Radium does not recommend injector brands or flow rates; ask your tuner. No fittings are included, and ORB fittings are required in those ports, chosen to suit your hose and accessories. Leave clearance around the ports if you plan to fit a regulator, gauge, or damper, since those need space. The center port accepts a Radium FPD-R or FPD-XR pulse damper, and a DMR regulator fits either end. For the M54's returnless fuel system, the 20-0807-PK plumbing kit connects this rail to the factory feed line.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBlack anodized laser etched fuel rail\u003c\/li\u003e\n\u003cli\u003eEngine-specific mounting hardware\u003c\/li\u003e\n\u003cli\u003eNOT included: AN fittings, fuel injectors, regulator, gauge, and pulse damper\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW M50, M52, M52TU, M54, M56, S50, and S52 engines\u003c\/li\u003e\n\u003cli\u003eIncludes the North American S50B30US\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNOT compatible with the ITBs found on the non-US S50B30 and S50B32\u003c\/li\u003e\n\u003cli\u003eNOT compatible with OEM M56 coupling-type fuel injectors\u003c\/li\u003e\n\u003cli\u003eAll fittings sold separately\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43700758347843,"sku":"20-0770","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/20-0770.jpg?v=1787353581","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-fuel-rail-bmw-m50-m52-m54-s50-s52-20-0770","provider":"Tuned by Shawn","version":"1.0","type":"link"}
