what is causing a fuel leak near the back axle after driving in the heat? on 1997 Cadillac Seville SLS

Occurs after driving awhile in the heat and gas runs out onto the ground after parking and engine is running?

Get it to a shop. Could be several things none of which can be diagnosed without visual inspection.If the fuel stops dripping shortly after you shut-off the engine it's probably a damaged fuel line, either way get checked before it go boom-boom.
