Bosch FP/K Series Fuel Supply Pump

without comments

This is a single-acting plunger pump usually mounted on the side of the main injection pump and driven off the pump camshaft. The pump can be equipped with a preliminary filter enclosed in a sediment bowl and also a hand primer as shown in Figure above. The hand primer is used to purge (bleed) air from the system if it has run dry or if the fuel filters have been changed.
