    Attached are pics of the oil pump, all plunger o rings are intact and there was no blockage inside the holes. The only thing i found was some light corrosion on the lower lip of the large disk that can be cleaned up. O ring will be replaced with a viton.

    I would replace the pump, the hose to #6 and blow out all the fittings for the injection system
    Leave no stone unturned.
    Thank You Leon Pugh

    Add to that a new check-valve/fitting for the reed plate on #6, make 110% certain there is nothing lodged in that passage.

    Looks like there's probably something restricting the passage downstream of the pump. Tiny little brass shard will do it.
