You'll be lucky if the plastic fuel inlet comes out without breaking. They're just pressed into the carb, but the plastic is very brittle.
I've posted links a few times, try a search for 5/16" fuel inlet or fuel inlet elbow. Harley, Arctic Cat, and others use the same inlet. Edit: I looked at some of the posts but the links I checked are no good.
This is what you need if the plastic one breaks.
