I use a gravity feed. You absolutely must do a thorough cleaning after doing pork. At worst it takes 1/2 an hour.
There’s great videos on how to do it.
You may also want to add a drip pan on the hot side. That seems to help even my heat and prevent grease fires.
Sorry for your troubles but FWIW this may be the funniest series of responses to a thread I’ve seen all year
