Abstract
A fuel injection pump has a drive shaft. A cam rotates together with the drive shaft. A plurality of plungers, slidably supported by a pump housing and driven by the cam, reciprocate in accordance with rotation of the cam to pressurize the fuel introduced in a fuel pressurizing chamber. The pressurized fuel is fed to an accumulator via a fuel feed passage formed in the pump housing. A pipe joint portion is integrally formed with the pump housing and is directly connected to a piping member of the accumulator.
