Abstract
A fuel injection pump with precipitate inhibiting features includes a pump body that defines a flushing fluid inlet and a flushing fluid outlet that open into a plunger bore. A plunger is positioned in the plunger bore and is moveable between a retracted position and an advanced position. The plunger has a first end separated from a second end by a side surface. A portion of the side surface and the plunger bore define a flush connection passage that connects the flushing fluid inlet to the flushing fluid outlet over a portion of the plunger's movement between its retracted position and its advanced position.
