Abstract
A piston fuel pump for an internal combustion engine includes a pump cylinder, a pump piston, and a seal. The pump piston is configured to be moved axially in the pump cylinder, wherein a working chamber is delimited by the pump piston. The seal is disposed on the pump piston and seals off the working chamber from a low-pressure region. The seal seals off an end section of the pump piston adjacent to the working chamber from the working chamber.
