Buddy put 2.5 gal DEF in fuel tank

[Canuck Stroker]

My neighbor dumped 2.5 gallons of DPF in his fuel tank this morning and drove it 3-4 miles before truck started to act up.
He got home and shut it down. No warning lights, but it ran like it was getting zero fuel or making boost.
I grabbed a bucket and went under to drain water separator, and it drained a white milkshake looking fluid. Filled a 2 gallon bucket after an hour of cycling key switch etc.

Finally got clear diesel to pour from separator and fired truck up... Do you think he will be fine? I know Ford will not cover this under warranty. Says so right in the manual!!

I would drain the entire tank and rinse it out with more diesel, if it was My truck.

The water seperator is designed for getting water out not urea...

This topic has been covered before too.

Thanks Big L,

I tried a search of DEF in fuel and got nothing back. If you know a link I would love to read more.

I wonder is this going to show fuel warning, codes?? Even if you got it fixed in time, can the Ford peoples claim on this. After all it did act up? I believe few tanks of diesel for flushing is cheaper than the fuel system replacement.

This is odd, yesterday I was reading a DEF in fuel story, and now I can't find it.

This is thread has alot of info, if you have an hour or so to read Ford won't fix my fuel system I know it's not the same thing, but alot of similar info.

DEF is prepared by dissolving solid high purity urea in deionized water to create a 32.5% solution in water. Knowing that, I'd completely drain the tank, put in a few gallons of diesel and cycle it through the system to get rid of the old fuel and then drain it also. After that, change the fuel filters. This would be the least I'd do. And really, I'd probably do the couple of gallon/filter flush a few times. The fuel system is just too expensive.

Easy to tell (see figures 10-13 in the attached file), probably already too late for the OP's neighbour's truck as the damage has already been done as the truck has been started and ran.
