[AT] [External] Diesel Fuel Question

You would think the filter would take care of things that could be harmful. But myself I'm not sure I would. Is it worth the few $$ of fuel "if" something else should happen? For me I'd say no.

Myself I would use the fuel for other purposes. Parts cleaning solvent. Mix 50/50 with used motor oil makes a good brush pile starter or to use the 50/50 mix on wood trailer decking (although be careful as it can be slick after a rain).

But that's just my .02.

Subject: [External] [AT] Diesel Fuel Question

I recently discovered I have a diesel fuel leak, and while trying to find time for diagnosis and repair, I started parking the tractor over a big drip-pan.  The pan collected roughly a gallon over the course of ... well, I can't say precisely but around a week or two.  That fuel dripped thru the normal grime found on engines, so it's pretty dirty.  (And I since discovered that turning off the fuel petcock effectively controls the leak)

I have filtered it multiple times.  First thru paper towel; clogged three or four getting that done.  Next thru coffee filters, again, it took 4 to finish the job.  Finally thru a Covid mask (regular surgical type not N95).  That one never clogged and captured very minimal additional material.

What I have now is therefore free of particulate big enough to catch in coffee filters and surgical masks.  It remains discolored; if fresh diesel was the color of Budweiser, this stuff looks like a nice brown ale.

What says the list?  Burn it?  Will the tractor's fuel filter take out everything big enough to cause problems with the pump or injectors?  (Seems like that should be a design criteria for that filter, no?)  If I do burn it, I will dilute it about 5:1 with fresh fuel.

If I don't burn it, it will eventually be carted away to our local Hazardous Waste Day held annually about 25 miles from here - I manage to remember and get over there only about once every 3-5 years.
