Abstract: A fuel flow limiter assembly includes a limiter body forming a central bore, and including a shutoff piston within the central bore having a closing hydraulic surface exposed to a fluid pressure of the fuel inlet, and being movable from an open position, to a closed position based on a fuel pressure drop from a fuel inlet to a fuel outlet in the limiter assembly. A fuel filter is resident in the limiter assembly and supported in a connector coupled to the limiter body. The fuel filter is elongate and projects from the connector into a fuel flow path from the fuel inlet to the fuel outlet.

Abstract: A fuel injector body 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 includes a sealing surface disposed axially between the first end and a shoulder. The first cavity defines a bottom surface and a peripheral surface defining a first cavity diameter, and the sealing surface defines a sealing surface diameter. A ratio of the sealing surface diameter to the first cavity diameter ranges from 0.3 to 4.4.
