My bio diesel fuel has a brownish gunk in it and it is plugging my primary filter. It is not bacteria problem (black specs in filter) I have been using Biocide.
Anyone have any ideas what could be causing this problem and what to do about it?
I haven't changed how I produce my bio diesel and this is the first time I have had this problem. I drive a few miles and the filter becomes cloged with this mes.
Any help will be appreciated.
