Most expensive and painful fuel filter change EVER...
So I'm changing my fuel filter on my csvt, I unplugged the fuse, ran the car till it died, got under the car and unplugged the filter and WOOSH, 40psi of fuel in my face. I rolled over to get out from under the car in a rush, and in doing so exposed my right ear to the line of sight of fuel, pouring half a gallon of fuel in my ear (with a couple splashes in my eye). Ran inside, flushed it out and called the paramedics.. They rushed over, flushed it out with some salt water for about 10-15 minutes and had a nice little chat with me while laughing at my ass for somehow managing to pour fuel in my ear.
Fuel filter: $6
Paramedics: $200
Learning how to change your own fuel filter: Priceless.
Lesson of the day: Unplug your gas cap when you replace your fuel filter.

Flame away....
