Abstract
A fuel rail is formed by a lost core process. The core is formed of metal, and then over-molded with plastic. The plastic over-molded metal core is immersed in a hot bath of glycolitin oil. The metal core melts, leaving the plastic overmold fuel rail. Attachment features can be formed in the fuel rail to attach fuel injectors by a snap fit connection, a threaded connection, or a twist and lock connection.
