Okay, so I recently acquired an '05 Hyundai Sonata GLS. It's got this massively annoying issue where I can't put more than 1/4 of a gallon of gas in it without it making the damn pump kick itself off. What gives? Is there something busted in the tank causing splashback?

Spiders in your vent line?
(Most likely not, but I want you thinking of spiders first, because SPIDERS)

Have you tried refueling with the nozzle pulled out just a little bit? My mom's Civic had a similar issue sometimes, but that seems to fix it.

I had a similar issue in my 04 Nissan Sentra SE-R. Mine was the vent control valve which is a little flap, essentially, that will close when the tank gets full causing the pump to stop. They usually get stuck in the open position which will allow the pumping of gas but won't stop the pump once full causing spillage. Or it gets stuck in the closed position, like yours and mine, which makes the pump think the tank is full and will continuously shut off. Took mine to the dealer to fix and it was ~$390.

Fuel track breather vent/tube is probably blocked (possibly by spiders). It is just a one way pathway for fumes to escape (tube or pipe with one way valves from the tank to atmosphere).
If that's not it you have a fuel neck problem, start by replacing the vent line, then if it's not fixed her the filler neck looked at (if it breaks you could experience fiery death).

My '01 Elantra was doing the same thing. The vapor evap canister needs to be replaced. I was told that gas can get in there if you top off the tank when filling up, and over time, deteriorate the canister.
Cost me about $600 to get it fixed. The part alone was $180.

Tried filling it as far out as the nozzle would go without pouring gas all over the side of the car. No dice.

Sounds like a venting problem. Others have given great advice about the vent tube and evap can. For a "just to get by" fix, try filling slower, only squeezing the pump handle part way to slow down the flow.

Where do you live now, and where did the car just come from? My old car did that too me when I drove from the coast up into the mountains in an afternoon. The rapid change in air pressure made the anti-siphoning valve stick shut and caused the same symptoms. After a day or two the pressure equalized and it worked fine again.
