Not quite as bad as winmutt's the other day (actually, nowhere close).....but still.
Finally got the 240d inspected and ready to be my daily driver yesterday (PO had antique tags on it - it needed lots of work to pass PA inspection). I've been driving it, ummm, not quite so legally for the past couple months - maybe 500, 600 miles total (2 or 3 fill-ups with regular diesel).....just to keep it running and test-drives and such.
In that time, I've plugged maybe 4 or 5 prefilters and changed my spin-on once.....as it's sputtered out on me on several occasions (the maiden voyage upon purchase, actually - fun times).
I've changed all the rubber fuel lines, drained the tank, replaced the tank strainer (suprisingly clean), treated with two bottles of startron, etc.
So this morning, excited to finally make the work commute (60 miles roundtrip) legally and post in the "old diesel daily driver thread" - I foolishly left my toolbox in my garage. Halfway to work, started losing power and had to pull over alongside a very busy highway. Fortunately, had a spare prefilter in the glovebox with a hose clamp. Unfortunately, no phillips screwdriver, only a flatblade. Lesson as always? I'm an idiot. So as semi's are flying past my head......I'm trying to chisel off my prefilter thru the braided rubber hose with the screwdriver. Finally get it replaced, late for work, covered in dirt and diesel fuel.
So my longwinded question is this... what does this gunk look like to you? I think my tank is clean, it's new fuel (and dino) and I've treated for algae/fungus/whatever. Where would it be coming from? I never blew my lines out with air, as I suppose I should have.....but would that much gunk (to clog 4-5 prefilters) live in the metal fuel lines?
Should I just continue treatments with startron tank cleaner? The gunk doesn't really look black like other photos I've seen on here. Changing filters every 200 miles seems a bit extreme too, especially since I'm not running bio
