Bending, and possibly kinking, an injector hard line might not be the best of ideas. Will it work, if you don't kink the line? Yes, it will work to make the engine run. However...
However, doing so will affect the effective timing of the engine, for that one cylinder. That one cylinder will fire slightly early. The timing is controlled very precisely by the injector pump. I believe that all the injector hard lines are the same length, though I haven't actually measured them. If one line is shorter than the others then the fuel put into that line will enter the cylinder slightly earlier, relatively speaking, than the other cylinders. This will affect that one cylinder, making it act slightly differently.
That, anyway, is my understanding. How drastically this will affect the running of the engine, I don't really know.
