    Yes and no
    theres a tandem pump on the side of the head (which also supplies vac for brakes ) this supplies low pressure fuel to the head via a fuel porting the injectors are in the the port or fuel way thats machined into the head
    then the injectors them selves are the high pressure pumps and injectors in one .

    You can turn ignition on and off repeatedly to kick the electric fuel pump in to pressure fuel around the filter as well as cranking .

    Yeah should of remembered this as you can hear the spirting through when ignition on huh, did you prime it as such with the bleed screw on top of filter casing if thats the correct wording, in my head it is lol.
