    there is a oring inside of the top cover of the pump and that is whats leaking. You have to remove the two nuts in the center of the top cover and remove the top cover. Then u can remove the trottle contral linage that is on top of the pump it is held on with a little nut and the trottle shaft can be taped out the bottom of the housing

    You can do it without removing the pump. But it is much easier to see what you are doing with the pump off, and much easier to knock crap off the intake manifold or somewhere else into the injection pump with it installed on the tractor. Removing the pump is simple and installing it properly is as well.
    We have too much gun control.
    What we need is more idiot control.
