1996 Dodge Caravan SE

Well, I just bought my dodge caravan and soon discovered that I coud smelll gasoline. When I looked underneath, there was a couple of drips but they slowed down and they eventually stopped. I can still smell the strong smell of gas but every time I've checked, I havent been seeing gas. However, THIS GREATLY CONCERNS ME. Will simply putting another metal clamp on the hose make the problem go away or is this problem stemming from something else? The leak seems to be right where the hose joins the tank.
