Fuel issue...

Hey y'all, so I finally got my new idler arm, and installed it. I put the front end back together, went to turn it over and... Notta. Car cranks and cranks but doesn't catch. I filled the float bowl in the carb, turned it over, and whammo! It starts right up, and runs until the float bowl was
Empty. I think the fuel pump is shot, but I just bought that pump... I did try cranking it over with the nasty fuel in the tank when I first installed the pump. What do you guys think? Pump, or something else?
