Abstract: An assembly for a fuel injector includes a fluid transportation member having a first portion that defines an internal passageway configured to convey fluid through the first portion, and a second portion in fluid communication with the first portion. The second portion defines at least one conduit configured to communicate fluid from the internal passageway out of the fluid transportation member and a structural reinforcement portion is colocated with the second portion. A housing is configured to receive at least a portion of the fluid transportation member.
