Fuel Leak

fuel leak on 1997 z71. Temperature out side -30. Truck starts, runs, and drives normal but smell of gas. Reason for leak? How to stop leak? Location of leak?

That's the fuel pressure regulator with the vacuum hose attached to it. Have you observed fuel leaking while it's running? Any chance it's spraying/leaking where the FPR attaches? I'm not that familiar with your model years rail system. If the two lines above the FPR are leaking and they "plug-in" to the rail there are seals that need to be replaced

FPR shouldnt take more than 5 min to swap out. Even if its cold its an easy job.

Yes it does leak where the two hoses attach vertically in to the fuel rail tube. The first morning that it was noticed a sizable amount of fuel was on the snow. Now just as the picture shows. The pressure in the line does leave the smell linger in the air for some time.
