Disclosed herein is an armature for a fuel injector. The fuel injector can have a longitudinal axis extending centrally therethrough. The armature can be configured to be positioned adjacent a gap in the fuel injector and configured to move along the longitudinal axis between first and second positions. In this regard, the armature can move in a proximal direction as the armature moves from the first position to the second position. Under these circumstances, fuel is forced out of the gap. The armature can move in the distal direction as the armature moves from the second position to the first position. Under these circumstances, fuel can be drawn into the gap. The armature can include a hydraulic separation feature configured to improve hydraulic separation of the armature such that a travel time between the first and second positions are reduced as the armature comes to rest. The hydraulic separation feature can include at least one of a modified mass, a modified overtravel diameter, and one or more diffusion holes.
