{"product_id":"mmx-hellcat-billet-aluminum-fuel-rails","title":"MMX Hellcat Billet Aluminum Fuel Rails","description":"The MMX Hellcat Fuel Rails are precision-engineered from 6061 billet aluminum to eliminate restrictive flow points found in OEM fuel systems. R\u0026amp;D testing revealed that factory rails are limited by small injector feed holes and narrow fuel pressure sensor openings, which these billet rails effectively enlarge to support higher performance requirements.\n\nTechnical specifications include a .686-inch internal rail diameter and .350-inch injector feed holes. Please note that these rails require either the MMX high-flow feed line kit or a return-style fuel system to operate properly; purchasing the rails alone requires one of these options to ensure adequate fuel supply. Fitment is compatible with OE 2.4\/2.7 superchargers, Whipple 3.0L superchargers, and the KONG 2650 supercharger.\n\nFor a complete upgrade, the optional MMX feed line kit utilizes the existing 1\/2-inch EFI OEM flex feed line, converting it to a 10AN line with a Y-block transition to 8AN outlets. This optional configuration relocates the fuel rail pressure sensor to the Y-block to further reduce restrictions and includes a plug-and-play electrical extension for a simplified installation.","brand":"Modern Muscle Xtreme","offers":[{"title":"Default Title","offer_id":52689275552056,"sku":"MMX-HLCT-FUEL-RAILS","price":349.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687392869.jpg?v=1784904460","url":"https:\/\/store.motormia.co\/products\/mmx-hellcat-billet-aluminum-fuel-rails","provider":"MOTORMIA","version":"1.0","type":"link"}
