A piston fuel pump for an internal combustion engine includes a pump cylinder and a pump piston that is configured to be axially displaced in the pump cylinder. A working chamber is defined by the pump piston. A seal is provided on the pump cylinder, which seals the working chamber counter to a low pressure region. The seal is applied directly to the pump piston by an injection molding method.

Piston fuel pump for an internal combustion engine

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.
