3pm today, had one towed in that the customer pumped 5 gallons of DEF into the fuel tank. He said that he didn't turn on the key, but I found DEF in the bottom fuel filter housing. Oh, well, I'll find out more Monday.

We're told to replace everything that the DEF touches. If you don't turn on the key, its not too bad. Lord help him if it's been started ($10,000).

For those of us who've never touched a wrench to anything newer than a 7.3...what's DEF?

DEF-----Diesel exhaust fluid. Urea that's injected into the exhaust pre-diesel particulate filter. It chemically breaks down NOX. Its extremely corrosive.

Ah...yeah, OK.

Sounds like an error you really want to avoid making.

I'm curious, what ever became of this one?
