With that big of a puddle, are you sure you don't have a seam leak from the tank itself, or a bad gas line on the top of the tank ? That's a lot of gas.......

pull hose off fuel pressure regulator and make sure diaphram is not ruptured/ pulling gas in through the vac line

Even if it did have a stuck injector with enough fuel to come out the tailpipe it would have hydrolocked that cyl or got caught up in the cats..or flooded over to the pass side from hpipe or even muffler before that. How the heck would it get over the axle?! Head hurts ouch. I agree with gas line broke or the seem in the tank has failed.
