How do I connect my new gas lines to the carburetor and primer bulb?

I am replacing the primer bulb and all fuel lines. all of the fuel lines were totally deteriorated so I don't know how the fuel lines come from the fuel tank to the carburetor. the unit is a Eager beaver 282 model 40012805, ser# 12-093268 the primer bulb has two stems for tubing -is the short stem a air vent? if I could see a schmetic ,it sure would help
thanks for your help
