Dumb mistake

I keep two diesel jugs in my truck bed:

The “good one” is for topping off the tank.

The other one is the fire starter.

Looks like you have a new Fire Starter jug.

If I offered to sell you an insurance policy that would cover your injector pump and injectors unconditionally for $20 would you buy it?

If you would then dump the 5 gallons of diesel fuel.

Im with the majority. Why take a chance for $20 bux or so of fuel.

Question is how to dispose of it.

If you feel lucky, use the fuel, but if you are wrong…big bucks.

The fuel isn't "damaged" but is is likely contaminated with water. The unknown is how much. Most diesels have fuel/water separating filters and a warning light on the dash for water in the fuel. That's all because diesel engines do not like having water in their fuel system. You could run the fuel and hope your filter catches it. It probably will. Or, if it doesn't it might damage a very expensive part(s) of your fuel system costing thousands of dollars to replace.
I don't think I'd run it.

Dump it for sure

Pour it into a clean 5 gallon bucket. Let it set for a day. Siphon 4-1/2 gallons of fuel off the top.

For me, peace of mind, is worth much more than 20 bucks!

Just dump it properly, start over, cheap lesson learned.

For $15-20 worth of diesel, I wouldn't want to mess with it.

If you really feel the need, used to have a water separating funnel on the boat. If you know someone who has one, you could run it back and forth between a couple jugs (but to buy one would be more than the fuel is worth).
