No danger in pulling the fuel line. I've been doing it for 30 years, and still have all my fingers, scar free no less! Keep in mind that the prop is mounted forward of the carb, and just don't stick anything you value in that area. Simple enough.
I must regretfully confirm that advice. Never suffered any harm from pulling fuel lines or other activities behind the prop. Sadly I have not had such happy results from fiddling with spinners or anything else in front of the prop.
