A pump, such as a rotary vane pump, roller cell pump, or gear pump for delivering diesel fuel, with a pump housing and a pumping unit that is arranged in the pump housing and driven for rotation via the drive shaft of a motor. The pump housing has an intake and an outlet, and the pump further has a hand pump unit that is integrally joined to the pump housing and delivers the fuel into the intake of the pump housing and thus into the flow path of the pumping unit.
