first time i tried to start it fuel went all through the brand new lines but after running for a minute it just stoped sucking fuel from the tank. changed the line that goes from the carb to the cranckcase didnt make a difference. it must be sucking air from somewere. any body got any ideas of whats happening here?

all gas lines and filters are brand new just replaced them. also cleaned the gas tank. it will start sucking but then it only goes up the line so far.
