Viking with a Hammer
I just pulled this sample out of the second filter on a 300 Kw John Deere today. (new HPP, common rail engine) I got at least 2 quarts of fuel out of the filters like this. Pretty safe bet it made it's way to the engine. If you had this in your diesel truck, you'd be making a "I hate brand X truck, lemon." thread on a forum somewhere right now. That JD engines filters, are way bigger and better than ours. (6090)
Hopefully the filter clogged with algae and rust chunks before this made it to the HPP and injectors. Looking at $14,000 repairs easy, if that's the case. And no warranty from this point forward. This is southern Michigan.
First bad batch of off road diesel in the N Mid West that I've seen in a decade. Possible leaky fuel tank, or water soaked fuel tank with a rusted top.
