I've got my fuel pump taken apart and when it came apart it flew apart because of the springs in it. And I can't fogure out how to put it back together. There's two screw type pieces that have notches in them that control the fuel flow. Idk which way to put it back in

I assume you are talking about your injector pump? if so, you need to take it to a diesel shop now, each delivery nozzle is calibrated to inject exactly the same amount of fuel, if one was flung out, you will never get it spot on without the right gear or tools :( For the average home tinkerer, only go in as deep as the delivery nozzles that the tube lines screw on to, any deeper and you are in too deep.
Sorry that i can't be of more help, but these parts are a little too complex.
