Roosamaster/Stanadyne pump is self-bleeding when all is right. So, it has no bleeder screw. But, as they get older and worn, it gets tougher to get the pump rid itself of air at slow cranking speed.
If the pump has been off, you can save a lot of wear and tear on the starter motor by priming it before installing. Easy to do with a hand-held oil squirt-can filled with diesel fuel.
When on the tractor, best you can do is - bleed at the inlet to the pump and make sure all air comes out. Then crack the injector lines loose at the injectors and crank until they dribble. Hooking an extra battery to it (in parallel) to increase cranking speed will make it bleed MUCH faster. If you can up cranking voltage even by one volt (9 to 10 volts), it will make a huge difference in cranking RPM and how fast that pump bleeds itself out.
