Well, scratch this one for now, upon closer inspection I found two rubber hoses joined together with a 'center' piece of metal and two clamps. The hose joint was spewing fuel upwards, and making it appear that it was cascading down from the gas tank. Middle hose, the one that passes behind the lower one, the joint is behind the lower hose, you can see only one of the clamps.
Notice how clean the area above the gas tank is...that's probably from gasoline being squirted on it for a prolonged period of time. I only use my convertible sparingly these days, so I didn't really notice the smell until recently. Hopefully I can repair this without too much fuss. In the meantime I have disconnected the battery, jacked the car up and put a bucket under it, going to just let it leak and let the pressure off the fuel line for a day, then tackle it tomorrow.
