    Patent number: 11441523
    Abstract: A fuel pump includes a pump holder having a sidewall extending from a first end to a second end which is closed off by an end wall, the pump holder having a fuel inlet. An upper plate located within the sidewall has an upper plate flow channel. A lower plate located within the sidewall has a lower plate flow channel and an outlet chamber is formed between the lower plate and the end wall. An outlet passage extends from the lower plate flow channel to a lower surface of the lower plate.
