I missed the memo about replacing my fuel filter every 30k, so it's been more like 100k since it's been replaced. Anyway, the car is a 2001 Buick Regal, and the fuel filter nut (not the quick connect, but the side closest to the front of the car) is stripped and rusted, and looks very similar to this
I've tried spraying White Lithium Grease on it to loosen it up, I'm going to have to get a 16mm wrench since it's stripped (It was a 17mm nut), but I'd really like to avoid towing it to the shop (won't run, fuel system issue) if possible.
