It sounds like there is some air being sucked into the injection pump along with the diesel. The hand priming pump often develops a leak, as do hardened rubber fuel lines. I rigged up a 12 volt fuel pump on mine to ensure that bugger all air gets into the system, it works well! I have seen a diesel blow clouds of blue smoke when the injector lines were put back on wrong,it's really easy to muck up on the pump end, the engine still ran though, just not very well. I can check out my injector pipe position on the pump if you don't have another to copy off!
