I didn't notice an o-ring when I reinstalled the pump, it's a rubber o-ring, correct? It's possible I damaged it or it fell off but I can't be sure. I'll take a look once my tank is lower on gas, I just filled up.

Where does the leak appear to be happening. Middle of the are or near the fuel tank door?

Jack and support the back of the car. Pull the driverside tire. Remove the plastic wheel well and inspect the filler tube and the hoses to the tank.
Look at the tank, does it appear fluid ran down the filler tube and dripped off the tank, only dripped off the tank..

These are your indicators. No smoke machine is needed, a few basic tools and some decent eye sight is all.
I filled up yesterday and looked on the ground and there was a lot of gas under the middle of the car. I'm going to check out the fill neck like you said because I guess that's also possible.
