How to test a coil and a fuel pump

My 51 is running really nice now with new points and condenser. However, the high speed shudder continues as before. When the car is warm, under heavy/moderate acceleration, it sputters and almost dies unless I back off on the accelerator. Then it smooths out and runs just fine. The two suspects are the coil and the fuel pump. How do I test each of them, short of replacing them? Or any other suggestions?
