I have a 79 M.B. 300sd that I am getting ready to convert.
Was thinking that until I have the filtering method down, maybe I should just have a setup where I replace the cubee's in the trunk of the car rather than putting in a permanent fuel tank........ any advice?

Also,
How do you know how many microns the filters are? Do they say on the box? And how far down should the WVO be filtered? 1 micron?

Thanks for any and all advice!
