Abstract

A piston fuel pump for an internal combustion engine includes: a pump cylinder; and a pump piston which is movably accommodated in the pump cylinder. The pump piston is guided radially with the aid of at least a first and at least a second guide section which are spaced axially apart from each other, the first guide section being situated in a pump cylinder of the piston fuel pump, and the second guide section being situated radially outwardly in the area of the end section facing the drive. The piston fuel pump has a supporting and sealing unit for the pump piston on the first guide section, which includes a guidance area for the radial guidance of the pump piston in the pump cylinder and a sealing area having a sealing lip.
