Anyone running homebrew biodiesel?

[bigjake6]

I was thinking about running biodiesel in my 2001 7.3 SD. I have access to plenty of veggie oil and a buddy who has been running hisown bio set up for 3 years now. I'm pretty sure I'll need to replace my fuel filter drain valve o-rings like JP did (awesome write-up JP) to prevent leaks. I'm told viton holds up well to biodiesel.

I was just wondering if anyone on the board, locally, was doing this.
