Hello All,

I just found this site & I think it's Great!! I'll probably be bothering you with a bunch of questions soon! I have an 82 240D that I'm running biodiesel in & love it.
Anyhow, my question is what is the micron rating of the secondary fuel filter? I'm looking to replace it with a Racor heated filter for cold weather & effiency(sp?). The Racor comes in a 10 or 2 micron rating & I'm just wondering which one I should use.

Thanks!
