I have the same problem on my 95 XE. But I see where its leaking from...up front on the engine.
If you have the hood up, and are looking at the engine, you will see just under the Distributor Cover a small rubber connector tube that seems to be "bridging" across an engine flex point. It has two hose clamps on each side. When the car is not on, I can see wetness there that is definitely gas. (finger test)
With the truck on, I can see the occasional drop of fuel fall off this tube.
Hope this helps with the Search. I will post back once I replace the tube with new piping. Looks to be 1/4" tubing, about 4 inches or so long.
