As far as I recall we can't buy a new stanadyne injection pump any longer. They are only rebuilt but make sure you get a good re builder. normally your pump becomes a core and they send you another rebuilt pump. Just make sure you take the parts off the pump you need to fit your new pump. These pumps have several pieces that will need to be taken off and installed on the new pump or you will probably never find those parts in a wrecked rig.
