Diesel Air Leak

I am having an issue with my diesel 2018 Ranger. There appears to be an air leak in my fuel system. When it sits overnight it will not start, the diesel fuel has bleed out of the fuel lines. Once I gravity feed the lines it runs great and the fuel pump keeps it running. I am not seeing any fuel leaks. So somewhere there has to be a very small hole that is allowing air into the line and that is enabling the lines to drain back into the tank.

I have replaced all the hose clamps and tonight will replace all the fuel lines. Does anyone know of a component in the fuel system that is prone to this?
