Filling Bowl on a 1970 340 engine

Hi, I was wondering if anyone knew of a way to fill the carb bowl on a 1970 340? I just got the engine back into the car, and I want to make sure that it runs. I am working on new fuel lines; I want to make sure I had everything correct unless I have to pull it back out. A picture would be great. I am a visual learner.
