A fuel injector body includes a body that includes an at least partially annular configuration defining a longitudinal axis, a circumferential direction, and a radial direction. A first counterbore and a first cavity extend from the first end toward the second end, and an external interface portion including a sealing surface is disposed axially between the first end and a shoulder. The first cavity defines a bottom surface and a peripheral surface, and the body also includes a leak passage extending from the bottom surface that is in communication with the first cavity.
