I had this happen 2 years ago after I changed my fuel lines in the
fall. I don't drive mine much in the snow. So when spring came, I
drove all the way to Las Vegas from Salt Lake City. Stayed with my
folks there and the next morning as I was 10 minutes enroute, the same
thing happened as you.  I smelled gas!!!!!  Yikes!!  Immediately
stopped on the exit, opened up the engine compartment as saw wet gas
pooled. Whoa!!  Not Good as I knew from this list.  I .knew I had used
the correct hose and clamps though

So I tightened (snugged) up the clamps and its been fine ever since.
Truly scary though knowing how fast they can become engulfed in fire
as shown on numerous YouTube vids. Glad you caught it fast.  Tighten
them up and keep an eagle eye on them until you're confident they
aren't leaking anymore.  Check to make sure its correct hose too.  As
mentioned here,  I think the cold/warm/cold temperature cycles of
winter/spring had some effect on the sealing of the new hose and
clamps. So check your clamps shortly after you install new ones just
to make sure.
