Default 2001 FLTHCUI Fuel Leak

I cannot for the life of me find this leak. Everything was working just fine on my 50 mile ride home, I stopped and filled up the tank and by the time I got home (2 blocks) I was leaking fuel all over the garage floor. No, I didn't overfill. The fuel was dripping out at a pretty quick rate.

I checked every line I could find, but cannot find anything that's leaking.
It appears to be on the left side somewhere. It drips off the crossmember just below the oil tank.
What am I missing?

Are you positive you aren't seeing fuel coming from the overflow line? A buddy of mine gets fuel on the ground for a couple of miles after every fill up. He insists on squeezing as much as he can into the tank, but just doesn't get it that he's just putting it on the ground. This would be made worse if it's a really hot day and the fuel is expanding in the tank.

Maybe from the quick disconnect where the fuel line leaves the bottom of the tank. The fuel may be dripping and running down the primary and dripping on the ground.

I'll double check, but I have never seen this much fuel leak out of there before, especially after siphoning 2 gallons out of the tank...

It's originating from somewhere closer to the engine, following its way back on the frame and then dripping off the crossmember.

Cross over line at the front of the tank?
