How to keep fuel up to the curb after shut off.

When I start my Cuda, After very many cranking attempts, It finally starts. After turning it off and it sits cold for a while, the gas has already dropped down through line and the same process begins again. Is there some sort of advice or device about how to keep the gas from exiting down the line and keep this issue from happening again? Is there an in-line stop ball check that would keep the fuel from backing down the line?

Any advice is greatly appreciated!
