Will DEF harm a CUT?

[Topzide]

Instructions say to open DEF nozzle door then press the yellow DEF button to dispense it.

I thought that was the case as you couldn't possibly have 1 nozzle for both! DEF in diesel is bad! Diesel in DEF is bad!

You didn't get anything mixed with your diesel that you dispensed.

Agree looks like dispenses both but on all the DEF equipment that I have been around the DEF nozzle is smaller in diameter.

If dispenses both through same nozzle I would buy my diesel elsewhere.

If the pump looks like this the DEF hose is separate.
