Beschreibung
Zusammenfassung:	A diaphragm type fuel pump includes a rod, one end of which is coupled to a diaphragm, a plunger which is slidably fitted with respect to the other end of the rod, and a plunger biasing member which biases the plunger toward the other end of the rod. The other end of the rod has a first pin extending outward radially. A through hole extends through the plunger in a radial direction. The through hole has a size which allows the first pin to move in a longitudinal direction of the rod. The first pin is in contact with one edge of the through hole. A gap is formed between another edge of the through hole and another end surface of the rod. A second pin in parallel to the first pin can be fitted into the gap.
