I have to "crank and pump" for a good 6-8 seconds when my truck is cold, especially if it's been a few days. On mine, anyway, I'm pretty sure the fuel is draining back toward the pump slowly as the truck sits, and the first several times I pump the gas I'm not getting any into the carb. But I don't have any backfire or smell raw gas... so perhaps it's a combo of my probable issue and the well plugs leaking on your truck.
