Biodiesel -- my first filter change

The other day I went to a gas station (Valley Oil in Mountain View, CA) that sells pure Biodiesel, well B99, so virtually pure Biodiesel. Anyway, a little more expensive than the B20 from Rotten Robbie but it's environmentally even better. Now, when you switch to Biodiesel fuel filter clogging after a few tanks of Biodiesel is pretty common. So I went ahead and changed. Thanks to the Cincinnati TDI Club it was super simple. They posted a video online on how to change the fuel filter. Took a mere 15 minutes and everything was done. Car runs great and I am still doing something good for the environment.
