Bad fuel leak
 

1994 mercury grand marquis
I rebuilt the engine and dropped it back in. I just started it up today and I idled it for a bit and it sounded alright turned it off and turned it on a few times. Then all of a sudden it wouldn't start (it turned but no longer started up) then I hear a very rapid dripping (more like a pouring) of liquid. I look under and put my hand out to catch the liquid and its gas. The gas is pouring from somewhere around the transmission cause the way its dripping is right in the back of the engine and dripping from the center of the transmission.. This worries me allot. I do not think that the dripping is coming from the engine itself but from a fuel line. I cant seem to narrow down exactly where though. Ill have to take a look at it tomorrow because it got too dark out. any ideas?
