Can't stop leak on new radiator hose.

I recently put new radiator hoses on my my Jeep. The top one keeps leaking at the thermostat housing neck. The antifreeze runs out of the hose almost as if the neck was not there. It seems to only leak in the mornings when it's cold. In the afternoon it does not leak. I thought my compression clamp was bad so I replaced it with type you tighten up with a nut driver or screw driver. Could my new hose be bad? I can't crank my clamp any tighter. My old one never leaked, I wanted to replace my hoses since I had to replace my radiator. Has this ever happened to anyone else? What would you recommend to fix this issue?
