Personally, I would not put an electric pump on a diesel. One of the big advantages of a diesel is that it can run without electricity. Not so, if you put that kind of pump on it. Around here, a pick and pull would sell that part for about $5.
I think you would have to hook up a cable to the mechanical shut off lever above the IP to get a manual shut off. My 409d which has nothing else vaccum on it, uses vacuum to operate the shut off. You'd have to use a diesel ignition switch to do it, but it might be easier to do that rather than cable up the manual shut off lever.
