anything smaller than 1 micron i dont think would be a problem. the diesel fuel doesnt even get filtered that fine.
That's true. The stock filter is either 2 micron or 5 micron, I don't recall which right off. So no, regular diesel doesn't get filtered that fine. It also isn't guaranteed to contain a ton of crap in that size range.
My personal feeling is I'd not do it. There is no way I could burn enough diesel at retail to pay for the cost of replacing the entire fuel system even if the used motor oil and filters were free. By my calculations, at $3.80 a gallon, your break even point is about 67,000 miles.
