Engine Won't Start......

Just tonight on the freeway my baby died on me and wouldn't start again. Just with a few minutes of trouble shooting i found the problem. I unplugged the hose from the carb and turned it over and no gas is coming out of the fuel line. Before I go work on it tomorrow i need some quick input. Am i looking at a new fuel pump?? Or sending unit in the tank?? Or something else i haven't thought of?? any input is appreciated.
